He was an only child to parents Sophia Voinarsky and Grigory Dobzhansky (a mathematics teacher). Dobzhansky was a religious man, a Russian Orthodox Christian, although he rejected beliefs such as the existence of a personal God. In 1910, at the age of 10, his family moved to Kiev, Ukraine where they fought through hunger because of WW1 and the Bolshevik revolution.
