Leonard Rose (July 27, 1918 – November 16, 1984) was an American cellist and pedagogue.

Rose was born in Washington, D.C.; his parents were immigrants from Kiev, Ukraine. Rose took lessons from Walter Grossman, Frank Miller and Felix Salmond and after completing his studies at Philadelphia's Curtis Institute of Music at age 20, he joined Arturo Toscanini's NBC Symphony Orchestra, and almost immediately became associate principal. At 21 he was principal cellist of the Cleveland Orchestra and at 26 was the principal of the New York Philharmonic.

He made many recordings as a soloist after 1951, including concertos with conductors such as Leonard Bernstein, Eugene Ormandy, George Szell and Bruno Walter among others. Rose also joined with Isaac Stern and Eugene Istomin in a celebrated piano trio.

Rose's legacy as a teacher remains to this day: his students from the Juilliard School, Curtis Institute and Ivan Galamian's Meadowmount Summer School fill the sections of many American orchestras, notably those of the Boston Symphony Orchestra, Cleveland Orchestra, Philadelphia Orchestra, and the New York Philharmonic. His pupils include Lori Singer, Raymond Davis, Desmond Hoebig, Peter Stumpf, Fred Sherry, Christopher von Baeyer, Myung-wha Chung, Thomas Demenga, Stephen Kates, Lynn Harrell, Yehuda Hanani, Hans Jørgen Jensen, Eric Kim, Bruce Uchimura, Donald Whitton, Yo-Yo Ma, Ronald Leonard, Steven Pologe, Sara Sant'Ambrogio, Matt Haimovitz, Richard Hirschl, and John Sant’Ambrogio. He played an Amati cello dated 1662, played today by Gary Hoffman. Rose died in White Plains, New York, of leukemia.

Glenn Herbert Gould (September 25, 1932 – October 4, 1982) was a Canadian pianist who became one of the best-known and most celebrated classical pianists of the 20th century. He was particularly renowned as an interpreter of the keyboard music of Johann Sebastian Bach. His playing was distinguished by remarkable technical proficiency and capacity to articulate the polyphonic texture of Bach’s music.

Gould rejected most of the standard Romantic piano literature and, after his adolescence, avoided Liszt, Schumann, and Chopin. Although his recordings were dominated by Bach, Gould's oeuvre was diverse, including works by Beethoven, Mozart, Haydn, Brahms, pre-Baroque composers such as Jan Sweelinck, and such 20th-century composers as Paul Hindemith and Arnold Schoenberg. Gould was well known for various eccentricities, from his unorthodox musical interpretations and mannerisms at the keyboard to aspects of his lifestyle and personal behavior. He stopped giving concerts at the age of 31 to concentrate on studio recording and other projects.

Isaac Stern (Ukrainian: Исаак Стерн, Russian: Айзек Стерн; July 21, 1920 – September 22, 2001) was a Ukrainian-born violinist and conductor. He was renowned for his recordings and for discovering new musical talent.

Isaac Stern was born into a Jewish family in Kremenets, Ukraine. He was fourteen months old when his family moved to San Francisco. He received his first music lessons from his mother, then in 1928 enrolled at the San Francisco Conservatory of Music, where he studied until 1931 before going on to study privately with Louis Persinger. He returned to the San Francisco Conservatory to study for five years with Naoum Blinder, to whom he said he owed the most. At his public début on February 18, 1936, aged 15, he played Saint-Saëns' Violin Concerto No. 3 in B minor with the San Francisco Symphony under the direction of Pierre Monteux. Reflecting on his background, Stern once memorably quipped that cultural exchanges between the US and Soviet Russia were simple affairs: "They send us their Jews from Odessa, and we send them our Jews from Odessa."

Leonid Hambro (June 26, 1920, Chicago – October 23, 2006, New York City) was an American concert pianist and composer.

He was the son of immigrant Russian Jews; his father was a pianist accompanying silent films.

He studied at the Juilliard School, and won First Prize at the National Naumburg Competition in 1946. He was the musical sidekick of Victor Borge for ten years, from 1961 to 1970 although he would occasionally perform with Borge throughout the remainder of Borge's career. In 1970 he became the Head of the Piano Department of the California Institute of the Arts, at Valencia, California, and Assistant Dean of the School of Music, holding these posts until 1992.

Leonid Hambro was Artist in Residence of the Aspen Institute and the official pianist of radio WQXR, New York. He played with the P. D. Q. Bach performances and the Hoffnung Musical Spoof Concerts. He published with Jascha Zayde The Complete Pianist (Ludlow Music Inc., New York). He also composed the piano piece Happy Birthday Dear Ludwig, a set of five variations on "Happy Birthday to You" in the style of many famous Beethoven pieces such as Minuet in G, Sonata Pathétique, Moonlight Sonata, Für Elise, and the Fifth Symphony.
