Oscar Nathan Strauss [sic] (1870-1954) was a highly-productive Viennese composer of operettas, orchestral music, film scores and songs. His most famous work, The Chocolate Soldier (1908), was ostensibly filmed by MGM, but little of Straus’s music was used.
Straus spent a few years working in America from 1930, during which time he contributed music to A Lady’s Morals and, perhaps more memorably, to two Lubitsch musicals, The Smiling Lieutenant (1931) and One Hour with You (1932).
Late in life, Straus provided the scores for two masterpieces by Max Ophuls, La ronde (1950) and Madame de… (1953).
