Leopold Godowsky (13 February 1870 – 21 November 1938) was a Polish-American virtuoso pianist, composer, and teacher.
 He was one of the most highly regarded performers of his time – known for his theories concerning the application of relaxed weight and economy of motion within pianistic technic – principles later propagated by Godowsky's pupils, such as Heinrich Neuhaus.
Garland Lorenzo Wilson (June 13, 1909 – May 31, 1954) was an American jazz pianist born in Martinsburg, West Virginia, perhaps best known for his work with Nina Mae McKinney.

Marty Napoleon (June 2, 1921 – April 27, 2015) was an American jazz pianist born in Brooklyn, New York, perhaps best known for having replaced Earl Hines in Louis Armstrong's All Stars in 1952.
 In 1946 he worked with Gene Krupa and went on to work with his uncle Phil Napoleon, a trumpeter, in Phil's Original Memphis Five.
 In the 1950s he also worked with his brother Teddy Napoleon, a pianist, and from 1966 to 1971 he performed with Armstrong again.
Baron Hans Guido von Bülow (January 8, 1830February 12, 1894) was a German conductor, virtuoso pianist, and composer of the Romantic era.
 One of the most famous conductors of the 19th century, his activity was critical for establishing the successes of several major composers of the time, especially Richard Wagner and Johannes Brahms.
 Alongside Carl Tausig, Bülow was perhaps the most prominent of the early students of Hungarian virtuoso pianist, conductor and composer Franz Liszt – therein performed the first public performance of Liszt's Sonata in B minor in 1857.
 He became acquainted with, fell in love and eventually married Liszt's daughter Cosima, who later left him for Wagner.
 Noted for his interpretation of the works of Ludwig van Beethoven, he was one of the earliest European musicians to tour the United States.

 She performed as a concert pianist from 1886–1896, and then worked as a piano and voice teacher.

The Virtuoso Pianist ("Le Pianiste virtuose") by Charles-Louis Hanon, is a compilation of sixty exercises meant to train the pianist in speed, precision, agility, and strength of all of the fingers and flexibility in the wrists.
 First published in Boulogne, in 1873, "The Virtuoso Pianist" is Hanon's most well-known work, and is still widely used by piano instructors and pupils.
 However, the applicability of these nineteenth-century exercises has been questioned by some piano instructors today.
Sidney Foster (May 23, 1917 — February 7, 1977), born Sidney Earl Finkelstein, was an American virtuoso pianist and teacher.
 He studied with Isabelle Vengerova and David Saperton at the Curtis Institute of Music in Philadelphia, and in 1940 became the first winner of the Edgar M. Leventritt Award.
 He was described as "an interesting, original pianist, the master of tonal shading and an artist."
Christian Leotta (born 1980 in Catania, Italy) is an award-winning Italian virtuoso pianist.

The Piano Concerto No. 3 in E flat major, Op.
 29 by Camille Saint-Saëns, was composed in 1869.
 The concerto is written in 3 movements.
 When the concerto was first performed by Saint-Saëns himself at the Leipzig Gewandhaus in 1869 it was not well received, possibly because of its harmonic experimentation.
 Saint-Saëns's third concerto is not as often performed as his famous second concerto, or the fourth or fifth concertos, but it is still an important addition to the piano concerto repertoire.
 It was dedicated to Élie-Miriam Delaborde, a pianist who is believed to have been the natural son of Charles-Valentin Alkan.
Alexander Glazunov composed his Piano Concerto No. 1 in F minor, Opus, 92, in 1911, during his tenure as director of the St. Petersburg Conservatory.
