Discussion of Pyotr Ilyich Tchaikovsky (May 7, 1840 – November 6, 1893)'s personal life, especially his sexuality, has perhaps been the most extensive of any composer in the 19th century and certainly of any Russian composer of his time. It has also at times caused considerable confusion, from Soviet efforts to expunge all references to same-sex attraction and portray him as a heterosexual, to efforts at armchair analysis by Western biographers. Biographers have generally agreed that Tchaikovsky was homosexual. He sought the company of other men in his circle for extended periods, "associating openly and establishing professional connections with them."  His first love was reportedly Sergey Kireyev, a younger fellow student at the Imperial School of Jurisprudence. According to Modest Tchaikovsky, this was Pyotr Ilyich's "strongest, longest and purest love". The degree to which the composer might have felt comfortable with his sexual nature has, however, remained open to debate. It is still unknown whether Tchaikovsky, according to musicologist and biographer David Brown, "felt tainted within himself, defiled by something from which he finally realized he could never escape" or whether, according to Alexander Poznansky, he experienced "no unbearable guilt" over his sexual nature and "eventually came to see his sexual peculiarities as an insurmountable and even natural part of his personality ... without experiencing any serious psychological damage." Relevant portions of his brother Modest's autobiography, where he tells of the composer's sexual orientation, have been published, as have letters previously suppressed by Soviet censors in which Tchaikovsky openly writes of it. Such censorship has persisted in the current Russian government, resulting in many officials, including the current culture minister Vladimir Medinsky, to outright deny his homosexuality.
Tchaikovsky lived as a bachelor for most of his life. In 1868 he met Belgian soprano Désirée Artôt. They became infatuated with each other and were engaged to be married but due to Artôt's refusal to give up the stage or settle in Russia, the relationship ended. Tchaikovsky later claimed she was the only woman he ever loved. In 1877, at the age of 37, he wed a former student, Antonina Miliukova. The marriage was a disaster. Mismatched psychologically and sexually, the couple lived together for only two and a half months before Tchaikovsky left, overwrought emotionally and suffering from an acute writer's block. Tchaikovsky's family remained supportive of him during this crisis and throughout his life. He was also aided by Nadezhda von Meck, the widow of a railway magnate who had begun contact with him not long before the marriage. As well as an important friend and emotional support, she became his patroness for the next 13 years, which allowed him to focus exclusively on composition. Tchaikovsky's marital debacle may have forced him to face the full truth about his sexuality; he never blamed Antonina for the failure of their marriage.
Vladimir Davydov (December 14 [O.S. December 2] 1871 – December 27 [O.S. December 14] 1906) was the second son of Lev and Alexandra Davydov, and nephew of Tchaikovsky, who called him "Bob". Although Tchaikovsky was infatuated with him, and although both were homosexual, there is no evidence that their relationship ever became sexual in nature.
