Dimitri Mitropoulos (; – 2 November 1960) was a Greek conductor, pianist, and composer. Life and career Mitropoulos was born in Athens, the son of Yannis and Angelikē Mitropoulos. His father owned a leather goods shop in downtown Athens. He was musically precocious, demonstrating his abilities at an early age. From the ages of eleven to fourteen, when Mitropoulos was in secondary school, he would host and preside over informal musical gatherings at his house every Saturday afternoon. His earliest acknowledged composition – a sonata for violin and piano, now lost – dates from this period. He studied music at the Athens Conservatoire as well as in Brussels and Berlin, with Ferruccio Busoni among his teachers. In 1921 he conducted the inaugural music of the Bavarian Socialist Republic. From 1921 to 1925 he assisted Erich Kleiber at the Berlin State Opera and then took a number of posts in Greece.

From 1937 to 1949 he served as principal conductor of the Minneapolis Symphony Orchestra (forerunner of today's Minnesota Orchestra). In 1949 Mitropoulos began his association with the New York Philharmonic. He was initially co-conductor with Leopold Stokowski and became the sole music director in 1951. Mitropoulos recorded extensively with the Philharmonic for Columbia Records and sought to reach new audiences in the city through appearances on television and by conducting a week of performances at the Roxy Theatre, a popular movie theatre.

In January 1960, he guest conducted the Philharmonic in a performance of Mahler's Fifth Symphony, which was recorded.
