Ian Ernest Gilmore "Gil" Evans (born Green; May 13, 1912 – March 20, 1988) was a Canadian jazz pianist, arranger, composer and bandleader.
 He is widely recognized as one of the greatest orchestrators in jazz, playing an important role in the development of cool jazz, modal jazz, free jazz and jazz fusion.
 He is best known for his acclaimed collaborations with Miles Davis.
Daniel Lee Knight (born September 26, 1953, Ottumwa, Iowa), is a jazz pianist, composer, educator, and author.
 His early piano education was in the classical tradition; his first piano teacher, Tillie Maither, was a former student of Ignace Jan Paderewski.
 His interest in jazz began at an early age, and by age seven he was already transcribing the works of Dave Brubeck, Erroll Garner and Duke Ellington.
 In 1958, on seeing NBC Television's "The Subject Is Jazz", the first ever television series on the subject of jazz, and whose Musical Director was jazz pianist Billy Taylor, he knew he had to become a jazz pianist, too.
Dave Flippo (born David William Flippo on March 1, 1958 in Pittsburgh, Pennsylvania), is a jazz pianist, composer, vocalist, teacher and bandleader based in the Chicago area.
 He is the leader of the Chicago-based modern jazz quintet FLIPPOMUSIC (originally FLIPPOMUSIC GLOBALJAZZ), an ensemble whose unique "globaljazz" approach to jazz and large body of original compositions has given it a special place in the Chicago jazz scene.
 Flippo is also a past member of slam poet Marc Smith’s Pong Unit Band.
Benny Morton (January 31, 1907 – December 28, 1985), born in New York City, was a jazz trombonist most associated with the swing genre.
 He was praised by fellow trombonist Bill Watrous among others.
 One of his first jobs was working with Clarence Holiday, and he appeared with Clarence's daughter Billie Holiday towards the end of her life on The Sound of Jazz.
 Morton was a member of pianist Teddy Wilson's Sextet throughout the early 1940s.
 In the 1960s he was part of the Jazz Giants band: "Wild" Bill Davison (cornet), Herb Hall (clarinet and alto), Claude Hopkins (piano), Arvell Shaw (bass) and Buzzy Drootin (drums).
 They toured the U.S. and frequently in Canada where they did some recording for Sackville Records.
 Towards the end of the 60's he played with an offshoot of the Jazz Giants under the leadership of Drootin, called Buzzy's Jazz Family, with Herman Autrey replacing Davison, Buzzy's nephew Sonny Drootin replacing Hopkins, and Eddie Gibbs replacing Shaw.
 That stated he is probably best known for his work with Count Basie and Fletcher Henderson.
Theodore Shaw Wilson (November 24, 1912 – July 31, 1986) was an American jazz pianist.
 Described by critic Scott Yanow as "the definitive swing pianist", Wilson's sophisticated and elegant style was featured on the records of many of the biggest names in jazz, including Louis Armstrong, Lena Horne, Benny Goodman, Billie Holiday, and Ella Fitzgerald.
 With Goodman, he was one of the first black musicians to appear prominently with white musicians.
 In addition to his extensive work as a sideman, Wilson also led his own groups and recording sessions from the late 1920s to the 1980s.
William James "Count" Basie (August 21, 1904 – April 26, 1984) was an American jazz pianist, organist, bandleader, and composer.
 His mother taught him to play the piano and he started performing in his teens.
 Dropping out of school, he learned to operate lights for vaudeville and to improvise accompaniment for silent films at a local movie theater in his home town of Red Bank, New Jersey.
 By age 16, he increasingly played jazz piano at parties, resorts and other venues.
 In 1924, he went to Harlem, where his performing career expanded; he toured with groups to the major jazz cities of Chicago, St. Louis and Kansas City.
 In 1929 he joined Bennie Moten's band in Kansas City, and played with them until Moten's death in 1935.
Peter Apfelbaum (born August 21, 1960) is an American avant-garde jazz pianist, tenor saxophonist, drummer and composer born in Berkeley, California.
 He first emerged on the jazz scene in the late 1970s, performing with Carla Bley from 1978–1982 and touring with Warren Smith and Karl Berger.
 Around this time Apfelbaum also studied and worked with musicians involved with the Creative Music Studio in Woodstock, New York.
 He graduated from Berkeley High School in 1978 in a class that included jazz pianist Benny Green.
William Ward Pinkett, Jr. (April 29, 1906—March 15, 1937) was an American jazz trumpeter remembered for playing two notable solos in recordings by jazz pianist and bandleader Jelly Roll Morton.
 His promising musical career was cut short by alcoholism and illness.
Douglas Clare Fischer (October 22, 1928 – January 26, 2012) was an American keyboardist, composer, arranger, and bandleader.
 After graduating from Michigan State University (from which, five decades later, he would receive an honorary doctorate), he became the pianist and arranger for the vocal group the Hi-Lo's in the late 1950s.
 Fischer went on to work with Donald Byrd and Dizzy Gillespie, and became known for his Latin and bossa nova recordings in the 1960s.
 He composed the Latin jazz standard "Morning", and the jazz standard "Pensativa".
 Consistently cited by jazz pianist and composer Herbie Hancock as a major influence ("I wouldn't be me without Clare Fischer"), he was nominated for eleven Grammy Awards during his lifetime, winning for his landmark album, "2+2" (1981), the first of Fischer's records to incorporate the vocal ensemble writing developed during his Hi-Lo's days into his already sizable Latin jazz discography; it was also the first recorded installment in Fischer's three-decade-long collaboration with his son Brent.
 Fischer was also a posthumous Grammy winner for "¡Ritmo!"
 (2012) and for "Music for Strings, Percussion and the Rest" (2013).
