According to the organisers of a 2009 Hrabal exhibition in Brno, his biological father was probably Bohumil Blecha (1893–1970), a teacher's son a year older than Marie, who was her friend from the neighbourhood. Marie's parents opposed the idea of their daughter marrying Blecha, as he was about to serve in the Austro-Hungarian Army.[2] World War I started four months after Hrabal's birth, and Blecha was sent to the Italian front, before being invalided out of service.[3] Blecha's daughter, Drahomíra Blechová-Kalvodová, says her father told her when she was 18 that Hrabal was her half-brother. Bohumil and his biological father never met formally, according to Blechová-Kalvodová.[3] Hrabal and Blechová-Kalvodová met twice; a dedication in a picture from 1994 says: "To sister Drahomíra, Hrabal!"[3]
