In his early years, Bob Hanf received drawing lessons from the legendary George Breitner. While studying in Delft he became friends with writers Hendrik Marsman and Simon Vestdijk. Hanf studied violin with Louis Zimmerman and played under the baton of conductor Martin Spanjaard. He later turned to composing. His varied oeuvre of unpublished works was discovered just a few years ago, rescued from oblivion.
