How Did Kir Bulychyov Die?

Kir Bulychev was a pen name of Igor Vsevolodovich Mozheiko, a Soviet Russian science fiction writer, critic, translator and historian. His magnum opus is a children's science fiction series Alisa Seleznyova, although most of his books are adult-oriented. His books were adapted for film, TV, and animation over 20 times – more than any other Russian science fiction author – and Bulychev himself wrote scripts for early adaptations.
