Alfred Kühn

Alfred Richard Wilhelm Kühn (22 April 1885 – 22 November 1968) was a German zoologist and geneticist. A student of August Weismann, he was one of the pioneers of developmental biology. At a period when biology was largely descriptive, he collaborated with zoologists, botanists, organic chemists, and physicists conducting interdisciplinary studies, examining sensory biology (colour vision), behaviour, and biochemistry through experiments on organisms.
