Nikolai Vavilov, an outstanding scientist of the 20th century, strove to end hunger in the world, but he died of starvation in prison in 1943. He was a pioneer of domestic genetics—he tirelessly studied plants and carried out complex expeditions to the most remote corners of the planet. However, his work became a victim of the politicization of science in Stalin’s time, and he couldn’t withstand the cynical pressure of Trofim Lysenko. The purge of geneticists dealt a huge blow to Russian science. Peter Pringle, reconstructing the story of Vavilov’s hunger death, used archival documents, personal correspondence, expedition reports, family letters, and eyewitness recollections. His account of the scientist’s life vividly shows his passionate devotion to science and his dream right up to the end.
