Vladimir Horowitz The Last Romantic

Vladimir Horowitz was the youngest of four children of Samuil Horowitz and Sophia Bodik, who were assimilated Jews. Samuil was a well-to-do electrical engineer and a distributor of electric motors for German manufacturers. Horowitz's grandfather Joachim was a merchant (and an arts-supporter), belonging to the 1st Guild. This status gave exemption from having to reside in the Pale of Settlement. Horowitz was born in 1903, but in order to make him appear too young for military service so as not to risk damaging his hands, his father took a year off his son's age by claiming he was born in 1904. The 1904 date appeared in many reference works during the pianist's lifetime.

In 1933, in a civil ceremony, Horowitz married Toscanini's daughter Wanda. Although Horowitz was Jewish and Wanda Catholic, this was not an issue, as neither was observant. As Wanda knew no Russian and Horowitz knew very little Italian, their primary language became French. They had one child, Sonia Toscanini Horowitz (1934–1975). It has never been determined whether her death, from a drug overdose, was accidental or a suicide.

Despite his marriage, there were persistent rumors of Horowitz's homosexuality.Arthur Rubinstein said of Horowitz that "Everyone knew and accepted him as a homosexual." David Dubal wrote that in his years with Horowitz, there was no evidence that the octogenarian was sexually active, but that "there was no doubt he was powerfully attracted to the male body and was most likely often sexually frustrated throughout his life." Dubal observed that Horowitz sublimated a strong instinctual sexuality into a powerful erotic undercurrent which was communicated in his piano playing. Horowitz, who denied being homosexual, once joked "There are three kinds of pianists: Jewish pianists, homosexual pianists, and bad pianists."

In the 1940s, Horowitz began seeing a psychiatrist. According to sources, this was an attempt to alter his sexual orientation. In the 1960s and again in the 1970s, the pianist underwent electroshock treatment for depression.

In 1982, Horowitz began using prescribed anti-depressant medications; there are reports that he was drinking alcohol as well. Consequently, his playing underwent a perceptible decline during this period. The pianist’s 1983 performances in the United States and Japan were marred by memory lapses and a loss of physical control. (At the latter, one Japanese critic likened Horowitz to a "precious antique vase that is cracked.") He stopped playing in public for the next two years.
