(b Paris, 22 Nov 1913; d Paris, 13 March 2002). French baritone. He studied in Paris and made his début at the Opéra-Comique in 1941 as Pelléas, which became his most famous role. He recorded it with Roger Désormière in 1942 and sang it frequently in Europe and America, including the Theater an der Wien, Vienna (1946), the Holland Festival, Amsterdam (1948), Covent Garden and the Metropolitan (1949). At the Opéra-Comique he also sang much operetta, to which his small but keenly projected voice was well suited; his roles there included Valérien in Reynaldo Hahn's Malvina (1945) and the title role in Gabriel Pierné's Fragonard (1946). At the Opéra he appeared as Ali in Jean-Philippe Rameau's Les Indes galantes (1952), and at Aix-en-Provence he sang Cithaeron in Rameau's Platée (1956). He was also a notable Danilo in Die lustige Witwe, a role he sang over 1500 times. Jansen appeared in a number of films, and provided the singing voice for several others.
