Warren Marrison

Canadian engineer and inventor of the quartz clock

Warren A. Marrison (21 May – 27 March )[2] was a Canadian engineer and inventor.

Warren marrison s biography wikipedia He received numerous patents for his work with quartz oscillators and was granted over 70 patents during his life. In , Warren Marrison, a year-old engineer at Bell Laboratories in New York, began work on a new frequency reference. The telecommunications revolution that occurred at the turn of the 20th Century was invariably accompanied by new technologies created to support the burgeoning industry sector. Day, Lance; McNeil, Ian

Marrison was the co-inventor of the first Quartz clock in [3]

Early life and education

Marrison was born in Inverary, Frontenac county, Ontario.[2] He studied at Queen's University in Kingston, Ontario, where he was part of a new program in engineering physics. He graduated in with a bachelor's degree in physics engineering;[4] his studies were interrupted by World War I when he served in the Royal Flying Corps as a radio technician.[2]

Beginning in , he studied at Harvard University, ultimately receiving a master's degree.[2] He worked at first for Western Electric in New York City, but moved to Bell Laboratories in New York beginning in [2]

Quartz clock

At Bell Labs in New York, Marrison was working on frequency standards using quartz as a reference.

It was in that he developed the first quartz clock while working with J.W. Horton. The clock used a block of crystal, stimulated by electricity, to produce pulses at a frequency of 50, cycles per second.[5] A submultiple controlled frequency generator then divided this down to a usable, regular pulse that drove a synchronous motor.[5] While this first version of the clock was crude; Morrison produced a more refined version in [2] A New York Times headline in October reported "Electrified Quartz Crystal Displaces Clock Pendulum".[6]

Legacy and awards

The invention would lead AT&T, the subsequent owners of Bell Labs, to develop a timepiece division called Frequency Control Products.[7] This would eventually become the company Vectron International.[7]

In Marrison was awarded a Gold Medal from the British Horological Institute.[8] In the Clockmakers Company awarded him the Tompion Medal.[2]

In Marrison was inducted into the Inventor's Hall of Fame.[9]
