Bernhard is the grandson of the distinguished Bohemian architect Leo Kammel (1885-1948). Between 1980 and 1995, Kammel studied architecture, theology and forestry in Vienna before going on to work for architectural firms, as a designer and as a forester. In the late 1970s, he published a number of short stories and reportage features in a range of print media while still attending high school and continued writing plays, lyrics and essays further on. In 2005, he founded his film production company and since then has made several films that have been invited to compete at A-list festivals and have also won awards. Currently, Kammel remains secluded in his conclave in the Alps for pursuing creative work such as writing novels and lyrics.
