Eric Allan Dolphy Jr. was an American jazz alto saxophonist, bass clarinetist and flautist. On a few occasions, he also played the clarinet and piccolo. Dolphy was one of several multi-instrumentalists to gain prominence in the same era. His use of the bass clarinet helped to establish the instrument within jazz. Dolphy extended the vocabulary and boundaries of the alto saxophone, and was among the earliest significant jazz flute soloists.
