Theodosius Dobzhansky (1900–1975)

Born 1900 CE, died 1975 CE.

Theodosius Grigorievich Dobzhansky (Russian: Феодосий Григорьевич Добржанский; Ukrainian: Теодосій Григорович Добржанський; January 25, 1900 – December 18, 1975) was a Russian-born American geneticist and evolutionary biologist. He was a central figure in the field of evolutionary biology for his work in shaping the modern synthesis and also popular for his support and promotion of theistic evolution as a practicing Christian. Born in the Russian Empire, Dobzhansky immigrated to the United States in 1927 at the age of 27. His 1937 work Genetics and the Origin of Species became a major influence on the modern synthesis. He was awarded the U.S. National Medal of Science in 1964 and the Franklin Medal in 1973. He is famous for his essay "Nothing in Biology Makes Sense Except in the Light of Evolution."
