Maria Augusta von Trapp (née Kutschera; 26 January 1905 -- 28 March 1987), also known as Baroness von Trapp, was the stepmother and matriarch of the Trapp Family Singers. She wrote The Story of the Trapp Family Singers which was published in 1949. The story served as the inspiration for the 1956 West German film The Trapp Family, which in turn inspired the Broadway musical The Sound of Music (1959) and the 1965 film of the same name.
