Wynton Learson Marsalis (born October 18, 1961) is an American trumpeter, composer, and music instructor, who is currently the artistic director of Jazz at Lincoln Center. He has been active in promoting classical and jazz music, often to young audiences. Marsalis has won nine Grammy Awards, and his oratorioBlood on the Fields was the first jazz composition to win the Pulitzer Prize for Music. Marsalis is the only musician to have won a Grammy Award in both jazz and classical categories in the same year.

Marsalis was born in New Orleans, Louisiana, on October 18, 1961, and grew up in the suburb of Kenner. He is the second of six sons born to Dolores Ferdinand Marsalis and Ellis Marsalis Jr., a pianist and music teacher. He was named after jazz pianist Wynton Kelly. Branford Marsalis is his older brother and Jason Marsalis and Delfeayo Marsalis are younger. All three are jazz musicians. While sitting at a table with trumpeters Al Hirt, Miles Davis, and Clark Terry, his father jokingly suggested that he might as well get Wynton a trumpet, too. Hirt volunteered to give him one, so at the age of six Marsalis received his first trumpet.
