Hats Off To The Hammond

July 3, 2017

He invented an automatic transmission system for cars, one type of 3-D glasses. a synchronous clock motor and infrared devices. But those of us who love rock and pop music love him for the invention that he gave his name to. We're paying tribute to Laurens Hammond, the creator of the Hammond organ.

This pioneer, born on 11 January 1895 in Evanston, Illinois, already had numerous inventions under his belt by the time he perfected the musical instrument that would go on to adorn so many great records. He had won his degree in mechanical engineering from Cornell University during World War I, and worked privately on a number of brilliant technological advances, including a silent clock that encased the spring motor in a soundproof box.

Hammond’s automatic transmission system was turned down by Renault, but he went on to develop the synchronous motor that would be the basis of both his clock and organ discoveries. By his early 30s, he’d formed his own Hammond Clock Company, which later became the Hammond Instrument Company and then, in 1953, the Hammond Organ Company.


Even by the 1930s, Hammond had a fascination for the sounds coming from the phonograph turntables in his laboratory, and started to explore the idea of producing musical tones by electric synthesis. By 1934, with John M. Hanert, he’d come up with the design for what became the Hammond organ, a machine with 91 small tonewheel generators, rotated by that synchronous motor of his.

The harmonic drawbars above the keyboard created the chance to mix millions of different tones. The organ was first manufactured in 1935, and millions of keyboard players — especially of his celebrated B-3 — have been in Mr. Hammond’s debt ever since. He died on 3 July 1973, at the age of 78. Here’s our playlist of some of the great tracks in music history, from Jimmy Smith to the Spencer Davis Group and from Deep Purple to the Allman Brothers Band,  to put his fantastic invention in the spotlight.

    I hauled a B-3 around for a number of years in the 70s & 80s.. great instrument, even went through a flood in 1972. I rebuilt it and hauled it around a few more years. I now use a Hammond SK1-88, it sounds great, but there was something about sitting behind that huge B-3 and letting it wail… Thank You Laurens!

    True all of the above – but what about the track Liquidator? That is one of the greatest Hammond tracks of all time.

    Great playlist demonstrating versatility of the instrument and the incredible talents across all genres! Long live the Hammond.

    Nice summary article, but I must object to the picture at the top. None of these great players, especially Jimmy Smith, would have been caught dead playing the model pictured! It’s not as if pictures of a real B-3 are hard to find!
