Heir to the Russian aristocracy of the 19th century, this renowned biologist fell into madness at the height of his scientific career. Interned in Germany, he threw himself body and soul into the creation of thousands of pages covered in gouache, charcoal or watercolour; thus opening, like a window in his cell, an escape into an infinite universe, a metaphysical escape. His fantastic works, when they are not abstract, are populated with ghostly characters: hybrid monsters, multicoloured insects, characters with disproportionate eyes, or small beings with the appearance of mutants.
His work, which captivated Daniel Cordier and Jean Dubuffet, is represented in important collections across the world, and thanks to a gift by Cordier, is in the permanent collection of the Paris Pompidou Center.
