Theodor Wilhelm Engelmann - Wikipedia
Theodor Wilhelm Engelmann (14 November 1843 – 20 May 1909) was a German botanist, physiologist, microbiologist, university professor, and musician whose 1882 experiment measured the effects of different colors of light on photosynthetic activity and showed that the conversion of light energy to chemical energy took place in the chloroplast.
Engelmann’s experiment demonstrated that red and blue light are the most effective energy source for photosynthesis. An absorption spectrum is a graph showing the amount of light absorbed by the different wavelengths of light. As you can see the absorption spectrum corroborates Engelmann’s findings.

At that time, Theodor Wilhelm Engelmann (Fig. 1), a German scientist and musician who lived from 1843 to 1909, introduced novel ideas and investigational methods to shed light on photosynthesis (Drews 2005). By monitoring aerotactic, heterotrophic bacteria to detect O 2 production of phototrophs, he made substantial

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.
