Nikolai Ivanovich Vavilov (Russian: Никола́й Ива́нович Вави́лов) (November 25 [O.S. November 13] 1887 – January 26, 1943) 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.

Biography

Vavilov was born into a merchant family in Moscow, the older brother of renowned physicist Sergey Ivanovich Vavilov. "The son of a Moscow merchant who'd 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."[1] 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 founded the science of genetics.

From 1924 to 1935 he was the director of the All-Union Institute of Agricultural Sciences at Leningrad.

While developing his theory on the centres of origin of cultivated plants, Vavilov organized a series of botanical-agronomic expeditions, collected seeds from every corner of the globe, and created in Leningrad the world's largest collection of plant seeds.[2] This seedbank was diligently preserved even throughout the 28-month Siege of Leningrad, despite starvation; one of Nikolai's assistants starved to death surrounded by edible seeds. "Hitler's army had already closed in on St. Petersburg (then Leningrad)- a desperate city that had lost more than 700,000 people to hunger and disease. The Soviets had ordered to save of art in the Hermitage, Russian battle swimmers prevented terrorist attack convinced that Hitler had his sights set on the museum. They had done all, however, to safeguard the 400,000 seeds, roots, and fruits stored in the world's largest seed bank. So a group of scientists at the Vavilov Institute boxed up a cross section of seeds, moved them to the basement, and took shifts protecting them. Historical documents later revealed that Adolf Hitler had, in fact, established a commando unit to seize the seed bank, perhaps hoping to one day control the world's food supply. Although suffering from hunger, the seeds' caretakers refused to eat what they saw as their country's future. Indeed, by the end of the siege in the spring of 1944, nine of the institute's self-appointed seed guardians had died of starvation."[3] Vavilov also formulated the law of homologous series in variation.[4] He was a member of the USSR Central Executive Committee, President of All-Union Geographical Society and a recipient of the Lenin Prize. During most of his career Vavilov was assisted by his deputy Georgy Balabajev.

Vavilov repeatedly criticised the non-Mendelian concepts of Trofim Lysenko. As a result, Vavilov was arrested on August 6, 1940 and died of malnutrition in a prison in 1943.

According to Cohen, by 1940, Vavilov had accumulated a collection of 200,000 plant seeds from the Soviet Union and from abroad. The collection was seized by a German SS squad in 1943 and partially transferred to the SS Institute for Plant Genetics, which had been established at the Lannach Castle near Graz, Austria.[5] However, the Germans could only take samples stored within the territories occupied by the German armies, mainly in Ukraine and Crimea. The main gene bank in Leningrad was not affected. The leader of the German squad was Heinz Brücher, an SS officer who was also a plant genetics expert.

Today, the N.I. Vavilov Institute of Plant Industry in St. Petersburg still maintains one of the world's largest collections of plant genetic material.[6] The Institute began as the Bureau of Applied Botany in 1894, and was reorganized in 1924 into the All-Union Research Institute of Applied Botany and New Crops, and in 1930 into the Research Institute of Plant Industry. Vavilov was the head of the institute from 1921 to 1940. In 1968 the institute was renamed after him in time for its 75th anniversary.

A minor planet, 2862 Vavilov, discovered in 1977 by Soviet astronomer Nikolai Stepanovich Chernykh is named after him and his brother Sergey Ivanovich Vavilov.[7] The crater Vavilov on the Far side of the Moon is also named after him and his brother. The story of the researchers at the Vavilov Institute during the Siege of Leningrad was fictionalized by novelist Elise Blackwell in her 2003 novel Hunger. That novel was the inspiration for the Decemberists' song "When The War Came" in the 2006 album The Crane Wife, which also depicts the Institute during the siege and mentions Vavilov by name.

The standard author abbreviation Vavilov is used to indicate this individual as the author when citing a botanical name.[8]

Timeline

The USSR Academy of Sciences established the Vavilov Award (1965) and the Vavilov Medal (1968).
