"Edward Kennedy "Duke" Ellington (April 29, 1899 - May 24, 1974) was an American jazz pianist, composer, and leader of his eponymous jazz orchestra from 1924 through the rest of his life. Music critic Ralph J. Gleason called him "America's most important composer".

Born and raised in Washington, D.C., Ellington was based in New York City from the mid-1920s and gained a national profile through his orchestra's appearances at the Cotton Club in Harlem. A master at writing miniatures for the three-minute 78 rpm recording format, Ellington wrote or collaborated on more than one thousand compositions; his extensive body of work is the largest recorded personal jazz legacy, and many of his pieces have become standards. He also recorded songs written by his bandsmen, such as Juan Tizol's "Caravan", which brought a Spanish tinge to big band jazz.

At the end of the 1930s, Ellington began a nearly thirty-five-year collaboration with composer-arranger-pianist Billy Strayhorn, whom he called his writing and arranging companion. With Strayhorn, he composed multiple extended compositions, or suites, as well as many short pieces. For a few years at the beginning of Strayhorn's involvement, Ellington's orchestra featured bassist Jimmy Blanton and tenor saxophonist Ben Webster, and reached what many claim to be a creative peak for the group. Some years later, following a low-profile period, an appearance by Ellington and his orchestra at the Newport Jazz Festival in July 1956 led to a major revival and regular world tours. Ellington recorded for most American record companies of his era, performed in and scored several films, and composed a handful of stage musicals.

Although a pivotal figure in the history of jazz, in the opinion of Gunther Schuller and Barry Kernfeld, "the most significant composer of the genre", Ellington himself embraced the phrase "beyond category", considering it a liberating principle, and referring to his music as part of the more general category of American music. Ellington was known for his inventive use of the orchestra, or big band, as well as for his eloquence and charisma. He was awarded a posthumous Pulitzer Prize Special Award for music in 1999."

Johnny Hodges was one of Duke Ellington's defining soloists, celebrated for his sensuous alto saxophone sound, lyrical phrasing, and commanding presence on ballads and blues, helping shape the unmistakable color of the Ellington reed section.

Otto "Toby" Hardwick was an early Ellington associate and a member of the Washingtonians circle, contributing alto saxophone and clarinet to several phases of the orchestra's development while remaining closely tied to Ellington's formative years.

Ben Webster brought a powerful new tenor saxophone voice to Ellington's orchestra, combining a robust, driving attack with a deeply romantic ballad style that became central to the celebrated Blanton-Webster era.

Harry Carney was Ellington's essential baritone saxophonist for more than four decades, anchoring the reed section with a rich, resonant sound and becoming one of the most influential baritone saxophone voices in jazz.

Barney Bigard was a New Orleans-born clarinetist whose fluid tone and Creole-inflected phrasing became a key element of Ellington's orchestra, particularly in the band's clarinet features and early-to-mid-period orchestral colors.

Rex Stewart was a cornetist known for his expressive half-valve effects, wit, and rhythmic bite, bringing a highly individual brass voice to Ellington after earlier work with groups including Fletcher Henderson's orchestra.

Ray Nance joined Ellington in 1940 as a multi-instrumentalist and vocalist, adding trumpet, violin, and singing to the orchestra and later becoming closely associated with several of the band's most memorable performances.

Wallace Jones was a trumpeter with Duke Ellington's orchestra from the late 1930s into the mid-1940s, contributing to the brass section during one of the band's most admired and heavily documented periods.

Joe "Tricky Sam" Nanton was one of Ellington's most distinctive trombonists, renowned for his plunger-muted "wah-wah" and "ya-ya" effects, which helped define the orchestra's earlier jungle sound and remained vital to its expressive language.

"Juan Vicente Tizol Martínez, commonly known as Juan Tizol, was a significant Puerto Rican musician and composer who made a lasting impact on the jazz scene in the United States during the 20th century. Born near San Juan, Puerto Rico, he was influenced by a rich musical environment, thanks in part to his uncle, a well-known musician who introduced him to various instruments. Tizol immigrated to the U.S. in 1920, eventually becoming a key member of Duke Ellington's orchestra, where he served as a copyist and contributed to the band's innovative sound. He is celebrated for his ability to fuse jazz with Latin music, pioneering the genre of Latin jazz and creating popular compositions like "Caravan," which features distinct Middle Eastern influences. Throughout his career, Tizol's works not only showcased his exceptional musicianship but also helped to elevate Latin American cultural sensibilities in the predominantly African American jazz scene of the time. He continued to perform and compose until his retirement in the 1960s, leaving behind a legacy of significant contributions to both jazz and Latin music. Tizol's influence remains evident in the music world, particularly through his enduring compositions that continue to resonate with audiences today."

Lawrence Brown was a technically polished and lyrically expressive trombonist whose elegant phrasing gave Ellington's trombone section a contrasting voice alongside the more growling, plunger-driven style of Joe Nanton.

Fred Guy was a long-serving Ellington rhythm guitarist and former banjoist who joined the band in its early Washingtonians period, helping sustain the orchestra's rhythm-section foundation through the swing era.

Jimmy Blanton transformed the role of the jazz bass during his brief time with Ellington, bringing unprecedented melodic freedom, rhythmic flexibility, and soloistic imagination to the instrument.

Sonny Greer was Ellington's longtime drummer and one of the orchestra's original associates, known for his colorful percussion setup, theatrical touch, and deep understanding of Ellington's ensemble drama.

Ivie Anderson was Ellington's first major full-time vocalist, prized for her warm tone, blues feeling, and effortless swing, and she remained one of the orchestra's signature vocal presences throughout the 1930s and early 1940s.

Herb Jeffries was a baritone vocalist and actor whose work with Ellington included the hit "Flamingo," bringing a smooth, relaxed vocal style to the orchestra during the early 1940s.
