Georg Ludwig Ritter von Trapp (4 April 1880 – 30 May 1947) was an officer in the Austro-Hungarian Navy who later became the patriarch of the Trapp Family Singers. Trapp was the most successful Austro-Hungarian submarine commander of World War I, sinking 11 Allied merchant ships totaling 47,653 GRT and two Allied warships displacing a total of 12,641 tons. His first wife Agathe Whitehead died of scarlet fever in 1922, leaving behind seven children. Trapp hired Maria Augusta Kutschera to tutor one of his daughters and married Maria in 1927. When he lost most of his wealth in the Great Depression, the family turned to singing as a way of earning a livelihood. Trapp declined a commission in the German Navy after the Anschluss and settled in the United States.
