The Hammond organ is an electric organ, invented by Laurens Hammond and John M. Hanert [1] and first manufactured in 1935. [2] Various models were produced, which originally used tonewheels to generate sound via additive synthesis , where component waveform ratios are mixed by sliding switches called drawbars and imitate the pipe organ's registers.
The Hammond Organ Company produced an estimated two million instruments in its lifetime; these have been described as "probably the most successful electronic organs ever made". [40] A key ingredient to the Hammond organ's success was the use of dealerships and a sense of community.
The Hammond clock model "Como" The Hammond Clock Company was founded in 1928 to produce and market clocks that were equipped with Hammond's new motor. The Hammond clock factory manufactured more than 100 different clock models, some simple and cheap, others made from expensive materials such as marble and onyx. [4]
The Hammond organ is an electric organ invented by Laurens Hammond and John M. Hanert [6] and first manufactured in 1935. [7] Multiple models have been produced, most of which use sliding drawbars to vary sounds.
After Hammond pioneered the electronic organ in the 1930s, other manufacturers began to market their own versions of the instrument. By the end of the 1950s, familiar brand names of home organs in addition to Hammond included Conn, Kimball, Lowrey, and others, while companies such as Allen and Rodgers manufactured large electronic organs designed for church and other public settings.
Simplified diagram of how a tonewheel works Goldschmidt tone wheel (1910), used as an early beat frequency oscillator. A tonewheel or tone wheel is a simple electromechanical apparatus used for generating electric musical notes in electromechanical organ instruments such as the Hammond organ and in telephony to generate audible signals such as ringing tone.
The organ pairs baseball with the tones of the past and present. And it was first heard over 80 years ago at Wrigley Field on Chicago's north side. On April 26, 1941 Ray Nelson entertained fans ...
Thanks to Hammond's prior manufacturing and engineering experience, the tonewheel generator was extremely well-engineered by the time the "Hammond Organ" finally went into production in 1935. Tonewheel organs are still in regular use in the twenty-first century, which is a testament to the quality of the design and execution of the product.
