Sergei Chetverikov

Sergei Sergeevich Chetverikov (Сергей Сергеевич Четвериков, 6 May 1880 – 2 July 1959) was one of the early contributors to the development of the field of genetics. His research showed how early genetic theories applied to natural populations, and has therefore contributed towards the modern synthesis of evolutionary theory.

Between the two World Wars, Soviet biological research managed to connect genetics with field research on natural populations. Chetverikov lead a team at the Nikolai Koltsov Institute of Experimental Biology in Moscow, and in 1926 produced what should have been one of the landmark papers of the modern synthesis. However, published only in Russian, it was largely ignored in the English-speaking world (though J.B.S. Haldane possessed a translation).

Chetverikov influenced several Russian geneticists who later came to work in the West, such as Theodosius Dobzhansky and Timofeev-Ressovsky, both of whom continued to work in a similar style. The significance of Chetverikov's work came to light much later, by which time the evolutionary synthesis was virtually complete.

He was arrested by OGPU in 1929 and sent to exile to Yekaterinburg for five years. He later moved to Nizhny Novgorod and organized the Department of Genetics at Gorky University. He was dismissed from his post at the behest of Lysenko in 1948.
