Life and early career

Horowitz was born on October 1, 1903, in Kiev, then in the Russian Empire (now Ukraine). According to Nicolas Slonimsky, Horowitz was born in Berdichev, a city near Zhitomir in the Volhynian Governorate. However, his birth certificate unequivocally states that Kiev was his birthplace.

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

His uncle Alexander was a pupil and close friend of Alexander Scriabin. When Horowitz was 10, it was arranged for him to play for Scriabin, who told his parents that he was extremely talented.

Horowitz received piano instruction from an early age, initially from his mother, who was herself a pianist. In 1912 he entered the Kiev Conservatory, where he was taught by Vladimir Puchalsky, Sergei Tarnowsky, and Felix Blumenfeld. His first solo recital was in Kharkov in 1920.

Horowitz soon began to tour Russia and the Soviet Union, where he was often paid with bread, butter and chocolate rather than money, due to the economic hardship caused by the Russian Civil War. During the 1922–23 season, he performed 23 concerts of eleven different programs in Petrograd alone. Despite his early success as a pianist, he maintained that he wanted to be a composer and undertook a career as a pianist only to help his family, who had lost their possessions in the Russian Revolution.

In December 1925, Horowitz emigrated to Germany, ostensibly to study with Artur Schnabel in Berlin but secretly intending not to return. He stuffed American dollars and British pound notes into his shoes to finance his initial concerts.
