Alexander Ilyich Siloti (also Ziloti, Russian: Алекса́ндр Ильи́ч Зило́ти, Aleksandr Iljič Ziloti, Ukrainian: Олександр Ілліч Зілоті; 9 October 1863 – 8 December 1945) was a Russian pianist, conductor and composer. His daughter, Kyriena Siloti, was also a noted pianist and teacher in New York and Boston until her death in 1989, aged 94.
Alexander Siloti was born on his father's estate near Kharkiv, Ukraine (then part of Imperial Russia). He studied piano at the Moscow Conservatory with Nikolai Zverev from 1871, then from 1875 under Nikolai Rubinstein, brother of the more famous Anton Rubinstein; from that year he also studied counterpoint under Sergei Taneyev, harmony under Pyotr Ilyich Tchaikovsky, and theory under Nikolai Hubert. He graduated with the Gold Medal in Piano in 1881. Siloti went to Weimar, Germany to further his studies with Franz Liszt, co-founding the Liszt-Verein in Leipzig, and making his professional debut on 19 November 1883. Returning to Russia in 1887, Siloti taught at the Moscow Conservatory, where his students included Alexander Goldenweiser, Leonid Maximov, and his first cousin Sergei Rachmaninoff. During this period he also began work as editor for Tchaikovsky, particularly on the First and Second piano concertos.
