Electric organ hammond

The Hammond electric organ revolutionized popular music with its unique sound and innovative technology since the 1930s.

About this subject

The Hammond electric organ, invented by Laurens Hammond in 1934, is an electromechanical musical instrument iconic in jazz, blues, rock, and gospel. Unlike pipe organs, the Hammond generates sound through tonewheels that produce electrical signals, later amplified by a Leslie speaker, which creates the signature vibrato and rotating effect. The B-3 model, released in 1955, is the most famous, used by artists such as Jimmy Smith, Booker T. Jones, and Keith Emerson. The Hammond revolutionized music by offering relative portability and expressive features like drawbars, allowing real-time harmonic mixing. Production of classic models ceased in the 1970s, but the sound remains influential, frequently emulated by modern synthesizers and software. Interestingly, Laurens Hammond also invented the first electronic chess game and missile guidance systems. The company still produces digital organs and workstations, yet the legacy of the original analog sound endures.
