Selig Hecht

Selig Hecht (1892 to 1947) was an American physiologist who studied photochemistry in photoreceptor cells. Hecht was born in Austria, and immigrated to the USA at an early age. His studies and talents led to Columbia University making him professor of biophysics in 1928.

Hecht began his study into light sensitivity with clams (Mya arenaria) and insects. His specialty was photochemistry, the kinetics of the reactions initiated by light in the receptors.
