Francis P. Bundy

Diamond Synthesis

U.S. Patent No. 2,947,611
Inducted in 2010
Born Sept. 1, 1910 - Died Feb. 23, 2008

Francis Bundy, along with Tracy Hall, Robert Wentorf, and Herbert Strong, synthesized diamonds as part of Project Superpressure, as announced by the GE Research Laboratories in 1955. The group used high pressure, graphite, and a catalyst to achieve diamond chips suitable for industrial applications.

The four researchers knew that graphite, a pure carbon substance, was key to achieving manmade diamonds. They discovered, however, that graphite was resistant to change due to strong bonding of the carbon atoms. By utilizing iron sulfide as a catalyst to weaken the carbon bonds and by applying high pressure, they were able to turn the weakened graphite into manmade diamonds for the first time in December 1954.

Diamonds have a wide variety of applications because of their exceptional physical characteristics, including hardness and heat conductivity, making them ideal for use in cutting, grinding, and polishing. Today, over 100 tons or over 450 million carats of synthetic diamonds are produced annually for industrial use.

Born in Columbus, Ohio, Bundy attended Otterbein College for his B.A. and Ohio State University for his Ph.D. He then taught at Ohio University before joining the Harvard Underwater Sound Lab during World War II. After the war effort, he joined GE. In 1987, he was the recipient of the Bridgman Gold Medal of the International Association for the Advancement of High Pressure Science and Technology.
