life and work
Gustav Senn was a student of the German botanist Georg Albrecht Klebs . He worked as a professor of botany at the University of Basel . He was a co-founder of the adult education center in Basel .
Senn was the first to study the light-induced movement and arrangement of chloroplasts. He carried out physiological studies on chloroplast migration in response to external stimuli. He determined light paths in cells by measuring the refractive indices and the optical density of the cell compartments. He demonstrated that chloroplasts migrate into the most favorable area for them in terms of light intensity. To this end, he published his groundbreaking work in 1908, Die Gestalten- und Lageverwechsel der Pflanzenchromatophoren .
After the publication of this book, Senn withdrew from studying chloroplasts. He turned to the exploration of the Greek philosopher Theophrastus .
Gustav Senn was accepted into the German Academy of Sciences Leopoldina in 1937 .
