In 1926, Nikolai Vavilov founded the world's first modern seedbank, and amassed a collection which today contains over 90% unique varieties of plant, contained in no other collection in existence. For his opposition to Lysenkoism he died in prison, and several of his colleagues famously starved to death instead of eating their specimens during the Siege of Leningrad.

The collection cannot be moved in time because it is a working seedbank of living plants.
