Career
Munk was president of the Expert Committee of the Union of German Philatelic Societies, and an international philatelic juror before World War Two. He signed the roll personally at the Brighton congress in 1933. Munk left Germany before the outbreak of war and continued his philatelic work in Switzerland where he did important research on early Swiss stamps.
A report in the Australian Stamp Monthly, 1 November 1937, states that sources in Germany believed that he was effectively in exile as a "non-Aryan".
