Wilhelm Friedrich Kühne was a German #physiologist known for his researches on #vision and the chemical changes occurring in the #retina under the influence of light.
His original work falls into two main groups—the physiology of #muscle and #nerve, which occupied the earlier years of his life, and the chemistry of #digestion, which he began to investigate while at Berlin with Virchow.
He was proposed the word #ENZYME meaning "in #yeast" (1878), and he isolated #TRYPSIN from pancreatic juice.
He demonstrated usefulness of cytophysiological investigations for solving problems of general physiology.
He devised an "artificial eye," discovered the light sensitive "visual purple" in the retina and was first to perceive migrating pigments in the living retina (1877-78).
