Willard Boyle

Willard Sterling Boyle,  (August 19, 1924 – May 7, 2011) was a Canadian physicist and co-inventor of the charge-coupled device. On October 6, 2009 it was announced that he would share the 2009 Nobel Prize in Physics for "the invention of an imaging semiconductor circuit—the CCD sensor".

A charge-coupled device (CCD) is a device for the movement of electrical charge, usually from within the device to an area where the charge can be manipulated, for example conversion into a digital value. This is achieved by "shifting" the signals between stages within the device one at a time. CCDs move charge between capacitive bins in the device, with the shift allowing for the transfer of charge between bins.

Often the device is integrated with an image sensor, such as a photoelectric device to produce the charge that is being read, thus making the CCD a major technology for digital imaging. Although CCDs are not the only technology to allow for light detection, CCDs are widely used in professional, medical, and scientific applications where high-quality image data is required.

After receiving his doctorate Boyle spent one year at Canada's Radiation Lab and two years teaching physics at the Royal Military College of Canada. In 1953 Boyle joined Bell Labs where he invented the first continuously operating ruby laser with Don Nelson in 1962, and was named on the first patent for a semiconductor injection laser. He was made director of Space Science and Exploratory Studies at the Bell Labs subsidiary Bellcomm in 1962, providing support for the Apollo space program and helping to select lunar landing sites. He returned to Bell Labs in 1964, working on the development of integrated circuits.

In 1969, Boyle and George E. Smith invented the charge-coupled device (CCD), for which they have jointly received the Franklin Institute's Stuart Ballantine Medal in 1973, the 1974 IEEE Morris N. Liebmann Memorial Award, the 2006 Charles Stark Draper Prize, and the 2009 Nobel Prize in Physics.

Boyle was Executive Director of Research for Bell Labs from 1975 until his retirement in 1979. In retirement, he split his time between Halifax and Wallace, Nova Scotia where he helped launch an art gallery with his wife Betty, a landscape artist. He was married to Betty since 1947, and has four children, 10 grandchildren and one gre
