After graduating in 1957, Hrabě moved to Prague and studied Czech language and History at the Faculty of Pedagogy.
Upon his discharge he took a variety of jobs as a laborer, librarian, writer for the literary magazine Tváře ('Faces'), until finally working as a teacher from 1964.
Hrabě was influenced by poets such as František Gellner, Allen Ginsberg, Vladimir Mayakovsky and François Villon.
Hrabě died of accidental carbon monoxide poisoning while asleep in his apartment in the Malá Strana district of Prague at the age of twenty-four.
His untimely death robbed Czech literature of one of the most important poets of his generation.
