Ivan Ivanovich Sollertinsky (3 December 1902 in Vitebsk – 11 February 1944 in Novosibirsk) (Cyrillic: Ива́н Ива́нович Соллерти́нский) was a Soviet polymath. He specialized in fields including linguistics, theatre, literature, history, and philology, but was most known for his work in the musical field as a critic and musicologist. He was a professor at the Leningrad Conservatory, as well as an artistic director of the Leningrad Philharmonic, and a prominent orator. In these capacities, he was an active promoter of Mahler's music in the Soviet Union. Sollertinsky was also interested in ballet and often wrote essays on the subject during the 1930s, along with teaching ballet history at the Leningrad Choreographic Institute. According to contemporaries – most famously Irakly Andronikov – he had a phenomenal memory, and supposedly spoke 26 languages and 100 dialects. However, Nicolai Malko claimed that Sollertinsky was able to speak 32 languages, some of which were also considered dialects.

Biography

Sollertinsky's father, Ivan Ivanovich Sollertinsky, came from a family of Russian Orthodox priests and served as a presiding judge, a privy councillor and a senator. His mother was Ekaterina Iosifovna Bobashinskaya, whose family belonged to a noble szlachta branch of the House of Sas.

Early in life he met Mikhail Bakhtin and took part in his philosophical meetings. After moving from Vitebsk to Leningrad, Sollertinsky graduated from the Leningrad University with a degree in Romano-Germanic philology, specializing in Spanish language and literature, particularly the works of Cervantes. In 1927 he became close friends with Dmitri Shostakovich, and is credited with introducing him to the works of Mahler, which had a profound impact on his composition style. Shostakovich's letters to Sollertinsky, written from 1927-1944, reveal many aspects of the composer's personality seen in few other sources, along with sharp opinions and crippling vulnerabilities.

Sollertinsky supported Shostakovich's opera, Lady Macbeth of the Mtsensk District, writing that it was an "enormous contribution to Soviet musical culture" in his 1934 review of it in Rabochii i Teatr (English: "Workers and Theatre"). In the wake of Shostakovich's first denunciation in 1936, Sollertinsky was called "the troubadour of formalism" by Pravda. Criticism of Lady Macbeth grew after its denunciation, resulting in mounting pressure on Sollertinsky to recant his previous statements, as he was largely blamed for influencing Shostakovich's "formalist" musical style by introducing him to the works of western composers. According to Isaac Glikman, a mutual friend of both Sollertinsky and Shostakovich, Sollertinsky did not denounce Lady Macbeth until Shostakovich told him to, out of concern for his safety. Once he retracted his previous positive statements on Lady Macbeth, Sollertinsky claimed that he would instead study the folklore of the Caucasus region and the Georgian language, perhaps to appeal to Stalin, a native of Georgia. While the denunciation did not deter Shostakovich and Sollertinsky's friendship, they did abandon plans to collaborate on a ballet adaptation of Don Quixote in 1936. On the night of February 10, 1944, Sollertinsky, feeling unwell, stayed at the house of the conductor A.P. Novikov. He died in his sleep at the age of 41 and was buried at the Zayeltsovskoye Cemetery. His funeral was attended by his students, colleagues, and admirers of his work.
