Donald Leslie, inventor and manufacturer of the Leslie speaker, died of natural causes at his home in Altadena. He was 93.
Leslie invented the speaker to make the compact electric Hammond organ sound like a large pipe organ. Leslie's invention was two rotations horns enhancing both treble and bass registers.
Leslie and the late Laurens Hammond were among the original inductees into the American Music Conference Hall of Fame in 2003.
