Sergei Vasilievich Rachmaninoff (April, 1873 – March 1943) was a Russian composer, pianist, and conductor, one of the last great champions of the Romantic style of European classical music.  "Sergei Rachmaninoff" was the spelling the composer himself used while living in the West throughout the latter half of his life. However, transliterations of his name include Sergey or Serge, and Rachmaninov, Rachmaninow, Rakhmaninov or Rakhmaninoff.

Rachmaninoff is regarded as one of the most influential pianists of the 20th century. He had legendary technical facilities and rhythmic drive, and his large hands were able to cover the interval of a thirteenth on the keyboard (a hand span of approximately twelve inches).  He also had the ability to play complex compositions upon first hearing. Many recordings were made by the Victor Talking Machine Company recording label of Rachmaninoff performing his own music, as well as works from the standard repertory.
