马里斯·杨松斯，Mariss Ivars Georgs Jansons (14 January 1943 – 30 November/1 December 2019[a][1][2]) was a Latvian conductor. During his lifetime, Jansons was often cited as one of the world's top living conductors.[3][4][5][6] He was best known for his interpretations of Mahler, Strauss and Russian composers such as Tchaikovsky, Rachmaninoff and Shostakovich.[3] Born in Riga, Latvia, Jansons moved to Leningrad (now Saint Petersburg) in 1956, where he studied conducting, and he received further training in Austria. He achieved prominence with the Oslo Philharmonic, where he served as music director from 1979 to 2000. He also directed the Pittsburgh Symphony Orchestra from 1997 to 2004, the Bavarian Radio Symphony Orchestra from 2003 until his death, and the Royal Concertgebouw Orchestra from 2004 to 2015.
