Original sentence: Although some historians continue to view him as heterosexual, others — such as Rictor Norton and Alexander Poznansky — conclude that some of Tchaikovsky's closest relationships were homosexual (citing his servant Aleksei Sofronov and his nephew, Vladimir "Bob" Davydov).Evidence that Tchaikovsky was homosexual is drawn from his letters and diaries, as well as the letters of his brother, Modest, who was also homosexual.However, von Meck's second daughter Alexandra—who had literally shocked her father to death by revealing to him that her sibling Milochka was actually not his child—told her mother about Tchaikovsky's homosexuality at the outset of her relationship with him.In 1850, his father was appointed director of the St Petersburg Technological Institute.Like his brother, Modest was also homosexual, although he too married.Meck's claim of financial ruin is disregarded by some who believe that she ended her patronage of Tchaikovsky because she supposedly discovered the composer's homosexuality.Tchaikovsky's homosexuality, as well as its importance to his life and music, has long been recognized, though any proof of it was suppressed during the Soviet era
