Jan Garrigue Masaryk (14 September 1886 – 10 March 1948) was a Czech diplomat and politician who served as the Foreign Minister of Czechoslovakia from 1940 to 1948. American journalist John Gunther described Masaryk as "a brave, honest, turbulent, and impulsive man".
In September 1938 the Sudetenland was occupied by German forces and Masaryk resigned as ambassador to Great Britain in protest, although he remained in London. Other government members including Beneš also resigned. In March 1939 Germany occupied the remaining parts of the Czech provinces of Bohemia and Moravia, and a puppet Slovak state was established in Slovakia. When a Czechoslovak government-in-exile was established in Britain in 1940, Masaryk was appointed Foreign Minister. During the war he regularly made broadcasts over the BBC to occupied Czechoslovakia.
He continued as Foreign Minister after the war and the communist takeover. On 10 March 1948 Masaryk was found dead, dressed only in his pajamas, in the courtyard of the Foreign Ministry (the Černín Palace in Prague) below his bathroom window. It was declared at various times to be suicide, an accident, and, most recently, as murder.Jan Masaryk in Wikipedia
