In 1883, Theodor Wilhelm Engelmann, a German scientist, wrote his essay "color and assimilation" (Ger.: "Farbe und Assimilation") describing the state of the art in photosynthesis research, his recent findings, and further assumptions based upon his presented results. Nearly 140 years later, many of his assumptions were proven correct.

Theodor Wilhelm Engelmann (14 November 1843 - 20 May 1909) was a German botanist, physiologist, ... Engelmann performed three significant experiments involving photosynthesis: In 1881, he observed the movement of bacteria towards the chloroplasts in a strand of Spirogyra algae. Engelmann hypothesized that the bacteria were moving in response ...
Contribution to the History of Photosynthesis: Theodor Wilhelm
In 1881, Theodor Wilhelm Engelmann designed an experiment for the simultaneous study of the light requirements and biochemistry of photosynthesis. He used the green alga Spirogyra, which has long chloroplast in each cell, as test organism. He placed the alga first in a drop of water which contained aerophilic (oxygen-requiring) bacterium to ...

Contributions of Theodor Wilhelm Engelmann on phototaxis, chemotaxis
Theodor Wilhelm Engelmann (1843-1909), who had a creative life in music, muscle physiology, and microbiology, developed a sensitive method for tracing the photosynthetic oxygen production of unicellular plants by means of bacterial aerotaxis (chemotaxis). He discovered the absorption spectrum of bacteriopurpurin (bacteriochlorophyll a) and the scotophobic response, photokinesis, and ...
Pictorial demonstrations of photosynthesis
Abstract. Theodor Engelmann's experiments in 1882 provided the first recorded visual demonstration of light wavelengths that are absorbed by photosynthetic pigments. Later, starch images in intact leaves were used to demonstrate photosynthesis in green plants. Similarly, light-induced chloroplast movements can form images in leaves as a ...

In plants and bacteria, one of the most important discoveries is photosynthesis. Theodor Wilhelm Engelmann played a key role in the discovery (Drews, 2005). The third example for the milestones in ...
Some pioneers of photosynthesis
A century later, Theodor Wilhelm Engelmann (1843-1909), a German physiologist (Figure 3), demonstrated the role of the colour of light in an experiment with filamentous algae (spirogynous type) illuminated with coloured spots, then with a prism, in which aerobic bacteria* serve as an indicator of oxygen production. Bacteria density was highest ...

Nearly 140 years later, many of his assumptions were proven correct.
Scientists have finally discovered how photosynthesis starts
