Greg Buckingham

Gregory Fenton Buckingham (July 29, 1945 – November 11, 1990) was an American competition swimmer, Olympic medalist, and former world record-holder in two events.
Buckingham was born in Riverside, California, and attended Menlo-Atherton High School in Atherton, California. He enrolled in Stanford University, and swam for the Stanford Cardinal swimming and diving team in National Collegiate Athletic Association (NCAA) competition.
At the 1968 Summer Olympics in Mexico City, he won a silver medal in the men's 200-meter individual medley, finishing second with a time of 2:13.0. His second-place performance completed an American sweep of the event with Charlie Hickcox winning the gold medal (2:12.0) and John Ferris taking the bronze (2:13.3). He also competed in the men's 400-meter individual medley and was judged to have finished fourth in the event final, even though his clock time was the same as the bronze medalist (4:51.4).
Buckingham died of a heart attack in 1990 at the age of 45. He was one of two older brothers of Fleetwood Mac guitarist Lindsey Buckingham.
