Leonid Iovich Gaidai was born on January 30, 1923 in Svobodny, Amur Oblast where he is commemorated by a statue. His father Iov Isidorovich Gaidai came from a Ukrainian family of serfs of the Poltava Governorate. At the age of 22 he was sentenced to several years of katorga for revolutionary activity and sent to the Far East to work at the railway. Leonid's mother Maria Ivanovna Lubimova was born in the Ryazan Oblast to Russian parents. She met Iov through her brother Egor, also a katorga worker who sent her a photo of his friend along with a marriage proposal. After Gaidai's term expired, they settled down in the Amur Oblast where Gaidai continued working at the railway building site.
