During the 900-day Siege of Leningrad in World War II, a group of Soviet botanists at the Vavilov Institute of Plant Industry faced an impossible choice. They were guarding the world's largest seed bank-tons of rice, wheat, and potatoes that represented the genetic future of global agriculture. Outside, people were resorting to cannibalism. Inside, the scientists were dying of hunger. They could have eaten the collection and survived. Instead, they chose to starve to death, one by one, protecting the boxes of grain from rats, cold, and thieves. This is the heart-wrenching true story of Nikolay Vavilov's disciples, who valued the future of humanity over their own present survival. A tale of scientific martyrdom that puts modern ethical dilemmas to shame.
