Hubert Masarik

Dr. Hubert Masarik (1896-1982) was a Czechoslovakian civil servant and diplomat. In 1938, he was a counselor with his country's Foreign Ministry. He and Dr. Vojtech Mastny were the two representatives Czechoslovakia sent to the Munich Conference in 1938. However, both men were directed to a hotel room by the Gestapo and detained while Neville Chamberlain, Edouard Daladier, and Adolf Hitler arranged for the Sudetenland region of Czechoslovakia to be surrendered to Germany.

Masarik published his memoirs after World War II.

Hubert Masarik in Hitler's War
Hubert Masarik and Vojtech Mastny were both waiting to hear the outcome of the Munich Conference when Konrad Henlein was assassinated. When it became clear that Adolf Hitler intended to use the assassination as a casus belli, British Prime Minister Neville Chamberlain suggested that Mastny and Masarik might be willing to give more concessions on behalf of their country. Hitler would not even consider further concessions.
