Page Created on 5/12/2013 and last reviewed 10/11/2015 by .

Credit for inventing the first fully automatic 'coffee making' machine goes to George Bunn, who's idea was patented on May 15, 1962. Even though drip coffee systems had been around for decades, George's invention is considered the first fully automatic coffee maker because it was the first machine that only required the user to add just the coffee & paper filter.

George Regan Bunn Biography

At Princeton he was a member of Cap and Gown Club. During WWII, he served with the Marine Corps on Peleliu in the South Pacific. Following the war, he joined Bunn Capitol Corp., where he served as chairman.

In 1957 he later founded and served as chairman of Bunn-O-Matic Corp, who perfected the fluted commercial paper coffee filter. Bunn-O-Matic claims credit for many firsts in the beverage industry, including the first commercial paper coffee filter in 1957, the first office coffee brewer in 1968, the first commercial brewer with water level control in 1975 and the first complete coffee management system 1992.

The family is careful to describe him as the founder and chairman of Bunn-O-Matic, rather than as an inventor. George was active in farming and enjoyed a lifelong involvement with horses. He also served on numerous boards over the years and supported many charitable organizations.
