The life and legacy of p.c ray : an indian scientist who helped build a nation.
PC Ray's contribution to the field of Science was a step towards nation-building. He was also a scholar who championed educational reforms, promoted employment through industry, and rallied for political advancement. Jashaswi Ghosh reflects on the legacy of an ancestor.
In a world engulfed by the COVID-19 pandemic, when the leaders of several countries have called for national self-sufficiency, I am prodded to reflect upon the immortal philosophy and works of my paternal Great Great Grand Uncle, Acharya Sir Prafulla Chandra Ray [P.C Ray] . Anointed the father of chemistry in India, Prafulla Chandra Ray was a strong advocate of making India industrially self-sufficient – a cause to which he dedicated his entire life.
P.C Ray was born on August 02, 1864 to a Zamindari family, in the village of Raruli-Kathpara, in the then Jessore district, which was a part of the Bengal Presidency of British India (current day Bangladesh). His family was a part of the affluent landed aristocracy and were the erstwhile Dewans of the Krishnanagar and Jessore Districts of the Bengal Presidency under the British East India Company.
Being born to educated and culturally refined parents (Harish Chandra and Bhubonmohini Devi), Prafulla Chandra Ray was encouraged into a life of learning and self-development. After an initial education at Raruli and Calcutta (in the later years), the Acharya wonthe Gilchrist scholarship offered by the University of Edinburgh and went on to pursue further education in Britain. After completing his B.Sc. and subsequently D.Sc. degree from the University of Edinburgh, Prafulla Chandra Ray was awarded the ‘Hope Prize’ for the thesis he had submitted for his D.Sc. degree which enabled him to continue his research for another year 1 .
After his return from England, the Acharya pursued his calling as a teacher, and researcher while spreading knowledge about chemistry in India. His utmost pursuit was to develop and encourage a scientific bent of mind in his students, which would free them from the prejudices that commonly infested the minds of Indians at the time. He encouraged the youth to have a free and rational thought process.
The Acharya was an immensely gifted scholar; he discovered several ground-breaking chemical compounds (eg: mercurous nitrite), published more than hundred and fifty research papers in famous science journals (eg: Journal of the Chemical Society of London); authoring many books on chemical sciences (eg: Life and Experience of a Bengali Chemist).
Amidst his other scholarly work, he also documented the history of Chemistry in India (ancient to medieval times).
His work was fuelled and guided by an inherently nationalistic spirit . He realized that for India to break the shackles of the overbearing colonial rule, the country needed to build a strong and independent scientific research base – something that was sorely lacking. This research base would then be the foundation on which the country could augment industrialization and thus ensure self-dependence and self-sustenance.
In Europe, industry and scientific pursuits have gone hand in hand · · · one helping the other · · ·the gigantic progress in industry achieved in Europe and America is a history of the triumph of researches in the laboratory. These thoughts were weighing heavy on me at the very threshold of my career at Presidency College. How to utilize the thousand and one raw products which Nature in her bounty has scattered in Bengal? How to bring bread to the mouths of the ill-fed… P. C Ray
It is important to understand the economical and political backdrop of the country which catalysed and triggered his above stated thoughts. The markets of India at that time were infested with goods which were manufactured in Britain using raw materials which had been supplied from India. These raw materials were sourced at a very cheap rate and the manufactured / finished goods which reached the markets of the country were heavily overpriced! This systematic drainage of wealth from India had seeded a bitter resentment and dissatisfaction amongst the larger Indian crowd fuelling movements favouring swadeshi goods and the boycott of British goods.
The Acharya, fuelled by the same sentiment took a step to facilitate the industrialisation of India and create jobs by founding the Bengal Chemical & Pharmaceutical Works, in 1901. The Bengal Chemical & Pharmaceutical Works was a success and with the help of several other scientists and nationalistic leaders it grew in size and multiple factories were established in different parts of Bengal and India.
If any one of you have used common household sanitisation products such as phenyl or naphthalene balls, you have been touched upon by the legacy of the Acharya!
Though multiple accolades were showered on him throughout his life (the most noteworthy being Companion of the Order of the Indian Empire in 1912 and the title of Knight Bachelor in 1919), he led a very simple and almost frugal life which he dedicated to the service of his Motherland!
Ray spent the last few years of his life in a laboratory room converted to a small apartment within the University College of Science at Calcutta University. This apartment now houses the P. C. Ray Museum. PC Ray imagined a nation’s growth to be the result of industrial, social, scientific and educational reform and he wholeheartedly contributed towards these. The moniker ‘Acharya’ is thus, apt for him – he who leads by example.

Dinsa Sachan re-tells the story of the inorganic chemist who put Indian chemistry on the map
When he wasn’t teaching or immersed in research, Prafulla Chandra Ray sometimes sauntered into college hostels and gave his favourite students a pep talk or drew them into a discussion about social issues concerning India, which was suffering under British rule at the time. It may seem like an odd pastime for a chemistry professor, but Ray’s work and public life were shaped by the politically charged times he lived in.
Ray, now regarded as one of the researchers who helped usher in an era of modern science in India, sailed back to his homeland in 1888 after acquiring a doctorate in chemistry from the University of Edinburgh. Around this time, important events leading up to India’s independence in 1947 were just beginning to take place. Even as Ray’s academic career at the Presidency College in Calcutta (now Presidency University in Kolkata) took off, he kept pondering how to exploit his scientific expertise for the greater good. ‘The history of the gigantic progress of industry achieved in Europe and America is a history of the triumph of researches in the laboratory,’ Ray reflected in Life and Experiences of a Bengali Chemist , his two-part autobiography.
The discovery of mercurous nitrite opened a new chapter in my life
When Ray founded Bengal Chemical and Pharmaceutical Works Limited (BCPW), the country’s first drugmaker, in the early 1890s, he hoped it would set a precedent for the youngsters of his home province. ‘In Bengal the one thing needful was not so much the establishment of Technological Institutes as the initiative, the dash, the pluck, the resourcefulness in our youths that go to the making of a businessman or an entrepreneur or a captain of industry,’ Ray lamented in his book. ‘The college-bred youth has been found to be a hopeless failure; there is no driving power in him; at best he can only shine as a tool or as an automaton.’
Ray’s firm, which is now a state-run entity, rolled out a slew of patent medicines, such as Aitken’s Tonic Syrup, Syrup of Hypophosphite of Lime and Tonic Glycerophosphate, to compete with British imports on drugstore shelves. Historians consider BCPW an important example of a movement called Swadeshi (a Hindi word that roughly translates to indigenous), that was launched in 1905 in response to the British government’s decision to partition Bengal into two provinces, widely seen as a divisive political act. As people spilled out on the streets to oppose the move, they also refused to buy British-made goods. The movement, which championed economic self-sufficiency, spurred an entire generation of entrepreneurs to make products locally. And using local raw materials had been top of Ray’s mind when he ventured into manufacturing pharmaceuticals. ‘To a large extent, for him, the matter of being a scientist and also being an entrepreneur was about bringing a strong new country into being,’ according to Benjamin Zachariah , a historian at the University of Trier in Germany .
Ray’s company may have been floated many years before the Swadeshi movement officially kicked off, but Zachariah and others believe that Ray was a pioneer of the movement. ‘But for him, Swadeshi was not this kind of trying to build an abstract indigenous Indian culture; he was interested in science,’ he says, adding that Ray tried not to get too involved in the country’s mainstream politics as he depended on the government for his paycheck.
While he juggled BCPW responsibilities along with university duties, Ray was indefatigable: ‘When work is coupled with a keen sense of enjoyment it does not tell upon your health; the very idea of locally manufacturing pharmaceutical preparations, which hitherto had to be imported, acted like a tonic.’ With the help of Ayurvedic experts, he even produced some traditional medicines. ‘[He] tried to see scientifically which of these were efficacious, and which were just superstition,’ says Zachariah. ’ Contrary to the way it’s done today, where a claim is made that the ancient Indians knew better than anybody else, he always made the claim that there’s a lot in the ancient Indian tradition which is just rubbish.’
Ray’s interest in traditional drugs stemmed from an authentic curiosity about the origins of chemistry. A little nudge from the eminent French chemist and science historian Pierre-Eugène-Marcellin Berthelot was sufficient for Ray to write A History of Hindu Chemistry . For the two-part treatise, Ray researched original Sanskrit and Pali texts to trace the evolution of the chemical sciences, as well as alchemy, through India’s earliest periods. It also, Zachariah says, translated scientific concepts in ancient Indian tradition into modern scientific vocabulary. Discussing ancient Indians’ metallurgical prowess, for example, Ray noted no rust had formed on the centuries-old Iron Pillar that continues to attract tourists in New Delhi.
Terming it a ‘classic’ in a 2014 Indian Journal of History of Science essay, Dhruv Raina , historian and philosopher of science at the Jawaharlal Nehru University in New Delhi, notes that the work equips ’practising Indian chemists with an anchor for their own historical and cultural bearings’. ’It’s one of the first disciplinary histories of science written by an Indian in English,’ explains Raina. The book also identified the socio-cultural reasons that derailed India’s early scientific progress. For example, as the society began to re-organise around caste, the higher castes began to steer clear of artistic as well scientific jobs: ‘The very touch of a corpse, according to Manu, is enough to bring contamination to the sacred person of Brahmin,’ Ray wrote in A History of Hindu Chemistry . ‘Thus we find that shortly after the time of Vagbhata, the handling of a lancet was discouraged and anatomy and surgery fell into disuse and became to all intents and purposes lost sciences to the Hindus.’ There is noticeable remorse and anger in his voice when he writes, ‘Her soil was rendered morally unfit for the birth of a Boyle, a Descartes or a Newton and her very name was all but expunged from the map of the scientific world.’
But Ray’s genius wasn’t just restricted to public engagement – it glowed equally brightly inside the lab. While the inorganic chemist racked up more than 150 papers in international publications through his career, Ray is celebrated for uncovering the chemical intricacies of nitrites , particularly mercurous nitrite that showed up as ‘yellow needles resembling prismatic sulfur’ while he was actually trying to prepare another compound using mercury and nitric acid as part of routine lab work during those days.
Ray bemoaned the absolute absence of mercurous nitrite from any reference literature on chemistry at the time in his 1896 paper in the Journal of the Asiatic Society of Bengal , where he revealed his discovery and described a method for preparing the elusive compound and the analysis that helped him identify it. ‘The discovery of mercurous nitrite opened a new chapter in my life,’ he remarked in the autobiography. Ray was elated because his international contemporaries noticed his work: ‘The appreciative and congratulatory letters from eminent chemists like Roscoe, Divers, Berthelot, Victor Meyer, Volhard and others not only filled me with inspiration but stimulated me to further activity.’
He had a very keen sense of his own public duty
Indeed, Ray and his group continued to tease apart the traits of mercurous nitrite over the next few years, also expanding their investigation to ammonium and alkylammonium nitrites. ‘In general, it got established that as a class nitrites are far more stable than chemists had supposed so far,’ wrote Animesh Chakravorty , an emeritus professor of chemistry at the Indian Association for the Cultivation of Science, in the Indian Journal of History of Science .
Ray may have stumbled across mercurous nitrite by chance, but Rajarshi Ghosh, associate professor of chemistry at the University of Burdwan in West Bengal, India, told Chemistry World it is the ‘brilliance of PC Ray that he didn’t ignore’ that yellow substance, something an ordinary researcher may have easily dismissed: ‘He had a very sharp chemical eye.’
The finding, however, remained controversial for some time. Other researchers couldn’t replicate it, and the compound’s structure remained a mystery. A few years ago, a group of Indian researchers, including Chakravorty, determined its structure using x-ray crystallography.
Throughout his career, Ray cultivated an army of young, brilliant chemists, who took on leadership roles in the scientific community. ‘He initiated a process of the institutionalisation of chemistry research [in India],’ says Raina.’
Ray deeply cared about the next generation and wrote his autobiography with them in mind. ‘This volume is affectionately inscribed in the hope that its perusal may in some measure stimulate them to activities,’ his dedication note stated. ‘There’s a lot of writing where he basically trying to insult people enough so that they realise that they’re just lazy, and they’re not doing anything, and then explaining to them what their own potential was, so that they would actually know what to aim,’ says Zachariah. Many of Ray’s mentees, including the Indian soil scientist Nil Ratan Dhar and astrophysicist Meghnad Saha , did groundbreaking work in their fields.
To help spruce up the chemistry department at the University College of Science, where he went to work after leaving Presidency College in 1916, Ray pledged his entire teaching income for almost 15 years. ‘He had a very keen sense of his own public duty,’ says Zachariah. ‘He felt he had a relatively privileged life. And that, therefore, he had to do to give back something to education, to the less privileged and to an abstraction called the country.’
Had Ray lived just three years longer, he would have been able to experience India as a free, independent country.

His manifold achievements in the fields of scientific research, pharmaceuticals as well as entrepreneurship, earned him the sobriquet ‘Father of pharmaceuticals in India’.
Born to Harish Chandra Ray, a wealthy landlord, and Bhubanmohini Devi in Raruli-Katipara village in Bangladesh on August 2, 1861, Prafulla Chandra Ray attended a school founded by his family till he was 9. After that, the family moved to Calcutta where he and his elder brother enrolled at the Hare School. In 1874, Ray had a bout of illness that forced him to take a break from studies.
With hindsight, he looked back at that tough period in life as a blessing in disguise as it enabled him to read extensively. He absorbed himself in biographies, articles on science, modern English and Bengali literature, history, geography, Greek, Latin, French and Sanskrit. He completed matriculation from Albert School in 1879 and enrolled in Vidyasagar College but since it did not offer science courses, he attended lectures in physics and chemistry at the Presidency College. Prompted by a keen interest in chemistry, he set up a laboratory at home to conduct experiments.
In 1882, he won the Gilchrist Scholarship to pursue a bachelor’s degree in science from the Edinburgh University. He received his doctorate degree in 1877. Besides science, he had also academic interests in literature, history and political science.
Ray began working at the Presidency College in 1889. He also discovered a chemical compound that was named mercurous nitrite. He was an active member of the Brahmo Samaj. Many institutions honoured his name such as the Prafulla Chandra College in Calcutta, and the Bagerhat PC College in Bangladesh.The British conferred on him with the Companion of the Order of the Indian Empire in 1911. He was also received honorary doctorates from the Durham and Dhaka universities.
A bachelor, he dedicated himself to scientific work and for the uplift of the downtrodden. In 1901, he set up the Bengal Chemicals and Pharmaceuticals Works Ltd with an initial capital of ~ 700 and the company grew manifold during his lifetime. In 1916, he left his job at Presidency College and took up the post of Palit Professor at the Rajabazar Science College. He also conducted research on platinum, iridium and sulphides of organic substances. He published over a hundred papers on Chemistry, its history and practical applications, many of which were published in the Journal of Indian Chemical Society. He was also deeply interest in ancient scientific texts and read ancient Sanskrit manuscripts in this connection. The result was a two-volume work titled A History of Hindu Chemistry from the Earliest Times to the Middle of Sixteenth Century which was published in 1902.
PHILANTHROPY
Ray was instrumental in organising relief work during the severe floods in Bengal in 1923. A rationalist who campaigned for social reforms, he opposed the caste system.His autobiography was titled Life and Experience of a Bengali Chemist. He instituted the Nagarjuna Prize for chemistry and the Ashutosh Mukherjee Award for biology.When Ray passed away in Calcutta on June 16, 1944, the mourners included thousands of his students.

Prafulla Chandra Ray (1861-1944) was an Indian scientist, professor, industrialist and philanthropist. He is known as the “father of Indian chemistry.” He established India’s first pharmaceutical company, ‘Bengal Chemical and Pharmaceuticals.’ He discovered the compound Mercurous Nitrite. Prafulla Chandra Ray also established the first modern Indian Research School in Chemistry.
Table of Contents
Prafulla Chandra Ray was born on Friday, 2 August 1861 ( age 82 years; at the time of death ), in Bengal Presidency, British India (now in the Khulna District, Khulna Division, Bangladesh). His early education started in his village school. He then went to Kolkata, where he studied at Hare School. In 1878, he was admitted to Metropolitan College (now, Vidyasagar College) as an F.A. student. He then pursued a B.A. course at the University of Calcutta. While studying at Metropolitan College, he studied physics and chemistry at Presidency College. In 1885, he received a B.Sc degree from the University of Edinburgh, United Kingdom.
Prafulla Chandra Ray was the son of Harish Chandra Ray and Bhubanmohini Devi. His father was a landlord, and his mother was a well-educated woman. Prafulla Chandra Ray had six siblings – four brothers, and two sisters.
Prafulla Chandra Ray never got married.

Nitrite chemistry, mercurous nitrite.
In 1895, Prafulla Chandra discovered the mercurous nitrite. The preparation of mercurous nitrite was an accidental discovery. He wanted to prepare water-soluble mercurous nitrate as an intermediate for the synthesis of calomel. Accordingly, dilute aqueous nitric acid was reacted with excess mercury. This resulted in the formation of yellow crystalline mercurous nitrate.

A remarkable contribution of Prafulla Chandra Ray was the synthesis of ammonium nitrite in the pure form via double displacement between ammonium chloride and silver nitrite. The success with the preparation of ammonium nitrite led Prafulla Chandra to develop the chemistry of alkylammonium nitrites. He prepared a family of such compounds by double displacement of alkylamine hydrochlorides and silver nitrite.

Acharya Prafulla Chandra Ray lived a life of extreme self-denial and became a symbol of plain living.
Only three months junior to Rabindra Nath Tagore, Acharya Prafulla Chandra Ray was born on August 2, 1861, in the village Raruli-Katipara in Khulna (now in Bangladesh) and died on June 16, 1944. Remarkably enough, Mahatma Gandhi was a few months junior to him – still Prafulla Chandra was a follower of Gandhiji’s ideology. In fact, Prafulla Chandra had started a campaign to propagate Khadi in the nook and corner of Bengal. A true patriot as he was, Prafulla Chandra never failed to help the revolutionaries of the country because he had full faith in their devotion and dedication to the country. His patriotism had started from the very grass roots of the country. His dress, his food, his behaviour and his everything was Indian. For teaching science, he preferred mother tongue to English language. For breakfast or lunch, he used to prefer puffed rice (in Bengali we call it Muri). His disciples used to recollect his words, why go for foreign things when alternatives are available indigenously.
The decade of 1860-69 in the nineteenth century was very important in India’s history. Thus, Animesh Chakraborty, a well-known inorganic chemist, wrote: “It was the best of times – the second half of the nineteenth century. The decade of 1860 – 69 alone saw the birth of Rabindranath Tagore, Motilal Nehru, Swami Vivekananda, Madan Mohan Malaviya, Asutosh Mookerjee, Lala Lajpat Rai, Srinivas Sastri and Mohandas Karamchand Gandhi. And of Prafulla Chandra Ray. A season of light and hope was descending on a languishing India.”
He lived a life of extreme self-denial. He became a symbol of plain living. Mahatma Gandhi said: “It is difficult to believe that the man in simple Indian dress wearing simple manners could possibly be the great scientist and professor.” He lived in a single room of University College of Science, Calcutta University. Its furniture consisted of an iron bedstead, a small table, a smaller chair and an almirah with shelves full of books, most of which are English classics. Prafulla Chandra was unmarried.
His father Harish Chandra Ray was a zamindar (landlord), who was closely associated with the cultural and intellectual leaders of those days in Bengal. For his liberal views Harish Chandra was branded a Mlechcha (foreign heretic) by his fellow villagers. Ray’s mother, Bhubanmohini Devi, was also an accomplished lady of enlightened views.
Ray’s early education was in his village school, founded by his father. However, he made very little progress in this school as he used to be frequently absent from the school. In 1870 his father permanently shifted to Calcutta mainly for proper education of his children. Describing his first impression of Calcutta, Ray, in his autobiography wrote: “In August 1870, I came to Calcutta for the first time. I spent the month of August in Calcutta, to my great joy, almost every day seeing new sights. I caught glimpses of a new world. A panorama of gorgeous vistas was opened to me. The new water-works had just been completed and the town enjoyed the blessings of a liberal supply of filtered drinking water; the orthodox Hindus still hesitated to make use of it as being impure; but the superior quality of water carried its own recommendation, by slow degrees, reason and convenience triumphed over prejudice, and its use became almost universal. The construction of underground drains had just been taken in hand.”
In 1871, Ray and elder brother Nalinikanta were admitted into the Hare School, founded by David Hare, and then located in one storey building. The school was shifted to its present location in 1872. While studying in Hare School, he suffered from a severe attack of dysentery, which hampered his health throughout his life. Later, he studied at Albert School, Calcutta.
In 1879 he passed the Entrance Examination of Calcutta University and entered the Metropolitan Institution. PC Ray developed his interest in science after reading the autobiography of Benjamin Franklin and his famous “kite experiment”. At that time, the Metropolitan Institution had no science classes or laboratories and Prafulla Chandra attended classes of physics and chemistry at the Presidency College, Calcutta. Here he was specially attracted by the chemistry courses of Professor Alexander Pedler. It was Pedler who first awakened his interest in natural science. While taking the science course for the BA degree, he was awarded in 1882 one of the two Gilchrist Prize Scholarships after an all India competitive examination. Without completing the course for his degree, Prafulla Chandra proceeded to the United Kingdom for further study and entered the Edinburgh University. In Chemistry, he was a pupil of Professor Alexander Crum Brown, FRS noted for his philosophical outlook and engaging personality. He obtained the B.Sc. degree in 1886 and the D.Sc. degree in 1887. He was awarded the Hope Prize. While being a student of Edinburgh University he was elected vice-president of Edinburgh University Chemical Society in 1888.
Prafulla Chandra returned to India in 1889 and joined Presidency College, Calcutta as Assistant Professor of Chemistry. Though at that time, the Chemistry Department of Presidency College did not boast of any well-equipped world standard laboratory, but a lot of original chemical experimentation occurred there. In 1896, he published a paper on preparation of a new stable chemical compound Mercurous Nitrite. This work made way for a large number of investigative papers on nitrites and hypernitrites of different metals, and on nitrites of ammonia and organic amines. He started a new Indian School of Chemistry in 1924. Ray retired from the Presidency College in 1916 and joined the Calcutta University College of Science (popularly known as Rajabazar Science College) as its first Palit Professor of Chemistry.
On the completion of his 60th year in 1921, he made a free gift of his entire salary to the Calcutta University from that date onward, to be spent for furtherance of chemical research, and the development of the Department of Chemistry in the University College of Science.
The first volume of Acharya Prafulla Chandra Ray’s celebrated work, The History of Hindu Chemistry, was published in 1902. The second volume was published in 1908. It was Marcellin Pierre Eugene Berthelot (1827 – 1907), who inspired Ray to undertake this monumental work. In the preface to the edition Ray wrote: “…I was brought into communication with M. Berthelot some five years ago – a circumstance which has proved to be a turning point, if I may so say, in my career as a student of the history of chemistry. The illustrious French savant, the Doyen of the chemical world, who has done more than any other persons to clear up the sources and trace the progress of chemical science in the West, expressed a strong desire to know all about the contribution of the Hindus, even went the length of making a personal appeal to me to help him with information on the subject. In response to his sacred call I submitted to him, in 1898, a short monograph on Indian alchemy; it was based chiefly on Rasendra Samgraha, a work which I have since then found to be a minor importance and not calculated to throw much light on the vexed question as to the origin of the Hindu Chemistry. M. Berthelot not only did me the honour of reviewing it at length but very kindly presented me with a complete set of his monumental work, in three volumes, on the chemistry of the Middle Ages, dealing chiefly with the Arabian and Syrian contributions on the subject, the very existence of which I was not till then aware of. On perusing the contents of these works I was filled with the ambition of supplementing them with one on Hindu chemistry.”
In his Presidential address to the Indian National Social Conference in 1917, Prafulla Chandra made a passionate appeal for removal of the caste system from the Hindu society. Ray was an ardent advocate of the use of the mother tongue as medium of instruction in schools and colleges. In recognition of his contribution towards the advancement and enrichment of Bengali language, he was elected the president of Bangiya Sahitya Parishad (1931-34). He realised that advancement of Indian and its people can happen only by economic advancement through development of new industries on scientific lines. He showed the way by investing his own money into forming Bengal Chemical and Pharmaceutical Works in 1893. This company culminated into the pioneer of chemical industry in India. Employment generation among Indians was another motto for establishing such an industry. In 1902, it became a limited company and grew up under his guidance.
Prafulla Chandra gave away most of his earnings in charity. According to one estimate, he spent nine-tenths of his income on charity. In 1922 he made an endowment of Rs. 10,000 for an annual prize in chemistry, named after the great Indian alchemist Nagarjuna. He also made an endowment of Rs. 10,000 in 1936 for a research prize in zoology and botany named after Asutosh Mookerjee. He supported many poor students. At the time of his retirement, Ray donated Rs. 1,80,000 to the Calcutta University for the extension and development of the Chemistry Department.
Prafulla Chandra is remembered for his part in the Bengal famine of 1922. A correspondent for Manchester Guardian wrote: “In these circumstances, a professor of Chemistry, Sir PC Ray, stepped forward and called upon his countrymen to make good the Government’s omission. His call was answered with enthusiasm. The public of Bengal, in one month gave three lakhs of rupees.” In 1923, Northern Bengal suffered a flood which made millions of people homeless and hungry. Prafulla Chandra organised Bengal Relief Committee, which collected nearly 2.5 million rupees in cash and kind and distributed it in the affected area in an organised manner.
Before I conclude this article, let me quote from the lecture of Rabindranath Tagore which he delivered while presiding over Acharya Prafulla Chandra Ray’s 70th birthday celebration: “It is stated in the Upanishads that The One said, ‘I shall be Many’. The beginning of Creation is a move towards self-immolation. Prafulla Chandra has become many in his pupils and made his heart alive in the hearts of many. And that would not have been at all possible had he not unreservedly made a gift of himself. Decrepitude will never wear the glory of this power in Prafulla Chandra as teacher out. It will extend further in time through the ever growing intelligence of youthful hearts; by steady perseverance countrymen, they will win new treasures of knowledge.”

Scientist of the day - prafulla chandra ray.
Prafulla Chandra Ray, an Indian chemist, was born Aug. 2, 1861. Ray is often referred to as the father of chemistry in India. Showing great promise in his studies as a young man in Bengal, he was awarded a fellowship to the University of Edinburgh in 1882, where he received his BS and then his PhD in 1887. In a day when organic chemistry was all the rage, he chose to pursue inorganic chemistry, becoming an expert in mineral salts, such as sulfates and nitrites. He returned to India in 1888 and the next year received a position at the Presidency College in Calcutta. He was unable to obtain a position in the imperial service because he was Indian, an affront to which he took public offense. Ray was an ardent Bengali nationalist for his entire life, and unfortunately did not live quite long enough to see that dream become reality.
First page of Chandra Ray’s paper on nitrites of mercury, in which he announced his discovery of mercurous nitrite, Journal of the Chemical Society of London , 1897 (Linda Hall Library)
In 1896, he announced a major discovery of a new compound, mercurous nitrite. It is hard to believe that in a millennia of alchemical and chemical investigations, no one had discovered this particular compound, which was quite stable once one figured out how to make it. He published the discovery in several papers, including one in the Journal of the Chemical Society of London in 1897 which we have in our collections ( second image ). The discovery spawned a novel field of research, allowing Ray to establish a new school of chemistry in India and attract a considerable number of students. In 1916, he joined the faculty of Calcutta University College of Science, where he established another chemical school. He retired in 1936 and died in 1944.

Ray was noteworthy for his passion for Indian independence and for his philanthropy. He lived extremely frugally, needed little money, and beginning in 1921, he donated his entire salary back to the Calcutta Department of Chemistry for research and student support. His humility and life style were as much a model for his students and contemporaries as was his expertise in inorganic chemistry. He also had an intense interest in the history of chemistry, and in 1902-08, he published A History of Chemistry in Ancient and Medieval India ; we have a later edition in the Library, retitled A History of Hindu Chemistry (1956). We hope to acquire the first edition at some point.

According to the Times of India in 2011 , the Royal Society of Chemistry awarded a Chemical Landmark Plaque to Ray in 2011, the first plaque ever given to a chemist outside of Europe. This story has been picked up by all the Wikipedia-style biographies, but there is something odd about it, since Landmark Plaques are given to places, not people, and there is no mention of this on the RSC website . We hope something about the story is true, since Ray certainly deserves more attention from the West. In India, he is a scientific hero, as he should be, and he was honored with a special exhibition at the Science Centre in Kolkata in 2011. We show here some photographs of that event ( fourth image ).

In India, Ray is always referred to as Acharya Prafulla Chandra Ray, Acharya being an honorary title meaning “one who leads by example.” It would be nice if we had a title for exemplary lifestyle in the West.

Amongst the histories of science produced in early twentieth century India, the History of Hindu Chemistry, authored by the `founder’ of the school of chemistry in modern India, P. C. Ray, has acquired the status of a classic. This paper explores, as part of a more detailed study, the nineteenth century histories and historiography of chemistry as presented in the works of Thomson, Hoefer and Kopp, that shaped the writing of Ray’s History. More specifically, it seeks to identify the historiographic elements and contexts of nineteenth century chemistry that Ray drew upon and subsequently improvised in order to insert the history of Indian alchemy and chemistry within the mainstream narrative of the histories of science of the late nineteenth and early twentieth century.

This paper takes a close look at the chemist Nilratan Dhar's memoirs published as Reflections on Chemical Education in 1974 and tries to understand how Dhar's renditions of his life and career bore the imprints of his teacher and mentor Acharya Prafulla Chandra Ray. It argues that Dhar drew upon Ray's historicizing impulse to tell us not only a story of his own life but also a larger history of chemical research under colonial conditions on the one hand and the Great Wars on the other.

After coming to Calcutta (Presently known as Kolkata) he was admitted to Hare School In 1879 he passed the Entrance Examination. Thereafter, he was admitted to the Metropolitan College. He was a truly brilliant student and got the Gilchrist Scholarship. After getting the scholarship he started for London. He got his B. Sc. Degree from the well known Edinburge university work on Chemistry. Later, he became to be known as a good scientist. He also got the D. Sc. title from the same university. He then started for Calcutta (Presently known as Kolkata).
After returning to Kolkata he started his career as a professor at the Presidency College. He also began his research here. He in fact started true research in Chemistry in our country. After strenuous research he invented Mercurous Nitrate. Accordingly, he became well-known as a great scientist. He also enriched Chemistry in many other manners. He (Later) became the Principal of Science College in 1913. He continued Ws research work there.
He also encouraged entrepreneurship. He always inspired others to start small scale industries and cottage industries. He himself got established the well-known, ‘Bengal Chemical and Pharmaceutical Works’. He wanted the Bengali people to become self-sufficient and hated slavery. He felt that the Bengalees must be strong-willed, confident and enthusiastic, so that they could become free not only the fetters of British rule but also from the shockless of unemployment. Thus the country would also get truly progressed and developed.
He also wrote some books. Some of his books are ‘History of Hindu Chemistry’, ‘Banglar Anna-Samasya’ and Ayurveder Prachinate’ etc. This books contained thoughtful essays. It is evident that he studied other subject besides Chemistry and had profound knowledge about the society, Economics and the people. He also felt for the sufferings of the impoverished people. He thought about the problems of starvation. He tried to find out the solution to eradicate starvation from the country.
He always wanted to help the helpless people. He established a ‘Relief Society’ to support the victims of famine and flood of North Bengal. So those people were immensely benefited.
