Mann's diaries reveal his struggles with his homosexuality, which found reflection in his works, most prominently through the obsession of the elderly Aschenbach for the 14-year-old Polish boy Tadzio in the novella Death in Venice (Der Tod in Venedig, 1912).[28]
Anthony Heilbut's biography Thomas Mann: Eros and Literature (1997) uncovered the centrality of Mann's sexuality to his oeuvre. Gilbert Adair's work The Real Tadzio (2001) describes how, in the summer of 1911, Mann had stayed at the Grand Hôtel des Bains on the Venice Lido with his wife and brother, when he became enraptured by the angelic figure of Władysław (Władzio) Moes, a 10-year-old Polish boy (the real Tadzio). Mann's diary records his attraction to his own 13-year-old son, "Eissi" – Klaus Mann: "Klaus to whom recently I feel very drawn" (22 June). In the background conversations about man-to-man eroticism take place; a long letter is written to Carl Maria Weber on this topic, while the diary reveals: "In love with Klaus during these days" (5 June). "Eissi, who enchants me right now" (11 July). "Delight over Eissi, who in his bath is terribly handsome. Find it very natural that I am in love with my son ... Eissi lay reading in bed with his brown torso naked, which disconcerted me" (25 July). "I heard noise in the boys' room and surprised Eissi completely naked in front of Golo's bed acting foolish. Strong impression of his premasculine, gleaming body. Disquiet" (17 October 1920).[29]

The attraction that he felt for Ehrenberg, which is corroborated by notebook entries, caused Mann difficulty and discomfort and may have been an obstacle to his marrying an English woman, Mary Smith, whom he met in 1901.[30] In 1950, Mann met the 19-year-old waiter Franz Westermeier, confiding to his diary "Once again this, once again love".[31] In 1975, when Mann's diaries were published, creating a national sensation in Germany, the retired Westermeier was tracked down in the United States: he was flattered to learn he had been the object of Mann's obsession, but also shocked at its depth.[32]
Although Mann had always denied his novels had autobiographical components, the unsealing of his diaries revealing how consumed his life had been with unrequited and sublimated passion resulted in a reappraisal of his work.[32][33] Thomas's son Klaus Mann dealt openly from the beginning with his own homosexuality in his literary work and open lifestyle, referring critically to his father's "sublimation" in his diary. On the other hand, Thomas's daughter Erika Mann and his son Golo Mann came out only later in their lives.
