riverboat in 1910, 1912, and 1914. The programs included many new works. After the 1917 Russian Revolution, he accepted a position as conductor of the newly named State Philharmonic Orchestra of Petrograd (1917–1920). In 1920, he left Soviet Russia for Berlin and Paris. In Paris he organized the Concerts Koussevitzky (1921–1929), presenting new works by Prokofiev, Stravinsky, and Maurice Ravel. In 1924 he took a post in the United States, replacing Pierre Monteux as conductor of the Boston Symphony Orchestra. However, he continued to return to Paris in the summers to conduct his Concerts Koussevitzky until 1929. In 1941 he and his wife became United States citizens. In America Koussevitzky's appointment as conductor of the Boston Symphony Orchestra (BSO) was the beginning of a golden era for the ensemble that would continue until 1949. Over that 25-year period, he built the ensemble's reputation into that of a leading American orchestra. Together with Gertrude Robinson Smith he played a central role in developing the orchestra's internationally acclaimed summer concert and educational programs at Tanglewood where today the 5,700-seat main performance venue bears his name. In the early 1940s, he discovered a young tenor named Alfred Cocozza (who would later be known as Mario Lanza), and provided him with a scholarship to attend Tanglewood. With the Boston Symphony he made numerous recordings, most of which were well regarded by critics. His students and protégés included Leonard Bernstein, Eleazar de Carvalho, Samuel Adler, and Sarah Caldwell. Bernstein once received a pair of cufflinks from Koussevitzky as a gift, and thereafter wore them at every concert he conducted. Personal life Koussevitzky's second wife Natalie died in 1942, and he created the Koussevitzky Music Foundations in her honor. In late 1947, he married Olga Naumova (1901–1978), Natalie's niece. Naumova had lived with the couple and acted as their secretary for 18 years. Olga Naumova was the daughter of the distinguished politician and civil servant Aleksandr Naumov (1868, Simbirsk – 1950, Nice, France) who served as Minister of Agriculture in the Russian Imperial Cabinet. She has been described as quiet, and soft-spoken, and Leonard Bernstein and Aaron Copland counted her among their close friends. His nephew Faviy Adolfovich Koussevitzky, known professionally as Fabien Sevitzky, was music director of the Indianapolis Symphony Orchestra from 1937 until 1955. Sevitzky changed his surname in order to mitigate accusations of nepotism against him. Koussevitzky died in Boston in 1951 and
