Werner Ritter von Trapp (21 December 1915 – 11 October 2007) was the second-oldest son of Georg Ritter von Trapp and Agathe Whitehead. He was a member of the Trapp Family Singers, whose lives were the inspiration for the play and movie The Sound of Music. He was portrayed as the character "Kurt".
The Trapps fled Austria after the German annexation of Austria, fearing reprisals resulting from declining to sing at Hitler's birthday party and Georg von Trapp's refusal to accept a commission in the German Navy. They went to the United States in 1938, settled in Vermont in 1942, and performed throughout the country. Georg Ritter von Trapp died in 1947 and the family eventually ceased performing.
^ ab"Maria Von Trapp's Stepson Dead at 91". Associated Press in Washington Post. 15 October 2007. Retrieved 5 January 2009. "Werner von Trapp, a member of the family made famous by the stage musical and the 1965 movie 'The Sound of Music,' died Thursday at his home in Waitsfield, Vt. He was 91. ... In the movie "The Sound of Music," Werner von Trapp was depicted by the character named Kurt."
^"Hitler's birthday party" was a national celebration in observance of Hitler's 50th birthday (April 20, 1939), and it consisted of a number of events held throughout the German Reich. The presence or absence of one singing group, more or less, is not likely to have triggered any reprisal.
^In 1938, Georg von Trapp was 58-years old, had recently lost all his money in a bank failure, and had not been inside a submarine since the end of the First World War. It seems doubtful that the German Navy, in 1938, would have been interested in pursuing such a person.
