Sir John Phillip William Dankworth, known in his early career as Johnny Dankworth, was an English jazz composer, saxophonist and clarinetist. He was the husband of jazz singer Cleo Laine.
Born in Woodford, Essex, he grew up, within a family of musicians, in Walthamstow in its suburb of Highams Park and attended Sir George Monoux Grammar School in Walthamstow. He had violin and piano lessons before settling eventually on the clarinet at the age of 16, after hearing a record of the Benny Goodman Quartet. Soon afterwards, inspired by Johnny Hodges, he learned to play the alto saxophone.
After studying at London’s Royal Academy of Music (where his jazz interests were frowned upon) and then national service in the army, he began a career on the British jazz scene. In 1949 he attended the Paris Jazz Festival and played with Charlie Parker. Parker's comments about Dankworth led to the engagement of the young British jazzman for a short tour of Sweden with the soprano-saxophonist Sidney Bechet. Dankworth was voted Musician of the Year in 1949.
