Nikolai Vavilov
Nikolai Ivanovich Vavilov ForMemRS was a prominent Russian and Soviet botanist and geneticist best known for having identified the centres of origin of cultivated plants. He devoted his life to the study and improvement of wheat, corn, and other cereal crops that sustain the global population.
Vavilov was born into a merchant family in Moscow, the older brother of renowned physicist Sergey Ivanovich Vavilov. The son of a Moscow merchant whod grown up in a poor rural village plagued by recurring crop failures and food rationing, Vavilov was obsessed from an early age with ending famine in both his native Russia and the world. He graduated from the Moscow Agricultural Institute in 1910 with a dissertation on snails as pests. From 1911 to 1912, he worked at the Bureau for Applied Botany and at the Bureau of Mycology and Phytopathology. From 1913 to 1914 he travelled in Europe and studied plant immunity, in collaboration with the British biologist William Bateson, who helped establish the science of genetics.
