Duke Ellington was a pioneering American jazz pianist, composer, and bandleader whose career spanned from the 1920s until his passing in 1974. Born in Washington, D.C., he rose to fame in New York City, leading his acclaimed orchestra at venues like the Cotton Club and helping to define big band jazz. Ellington created or co-wrote more than a thousand compositions, many of which became jazz standards, and was renowned for his innovative orchestration and expressive style. His long partnership with composer Billy Strayhorn produced some of his most celebrated works, including extended suites and classic recordings. Throughout his life, Ellington toured internationally, recorded extensively, and contributed music to film and stage. Celebrated for his versatility and vision, he described his work as "beyond category," influencing generations of musicians and earning a posthumous Pulitzer Prize for music in 1999.
