Nikolai Ivanovich Vavilov  (25 November 1887 – 26 January 1943) was a Russian botanist and geneticist.
He is best known for showing how and where crop plants evolved.
He devoted his life to agriculture: the study and improvement of wheat, corn, and other cereal crops.

By 1940, Vavilov had accumulated a collection of 200,000 plant seeds from the Soviet Union and from abroad.
He was widely admired, but his life came to a terrible end.
Vavilov repeatedly criticised a powerful but poor scientist, Trofim Lysenko.
As a result, Vavilov was arrested, and died of starvation in a prison in 1943.
Today Vavilov's name stands high.
The Vavilov Institute of Plant Industry in St. Petersburg is named after him.
It maintains one of the world's largest collections of plant genetic material.
