Oral History Information
Don Leslie, the inventor of the very successful Leslie Speaker, was pleased with the concept of the product that was a simple idea but a tricky design. As a child, Don was fascinated by the large pipe organs and how the sound traveled all around the listener. He had the goal of bringing that experience into the home. His speaker, which has a rotating sound-cone, uses the Doppler effect to create its unique sound. The speaker became popular when used with the Hammond B-3 organ and both seemed to be created for each other, even though they were not originally.
