Born March 21, 1944, Pine Bluff, Ark.

An outstanding sprinter for O'Dea High School in Seattle (9.5 for 100 yards in 1963), Greene developed into one of the world's top sprinters in the 1960s.

Competing for the University of Nebraska, the 5-8, 148-pound Greene won six national collegiate sprint titles (three indoors, three outdoors) from 1965 to 1967. Considered a sure bet to make the 1964 Olympic team, Greene suffered muscle pulls that held him to a sixth place at the Olympic Trials. By 1968, however, Greene was back and better than ever, setting world records in both the 100 yards and 100 meters. At the 1968 Championships in Sacramento, Greene and Jim Hines made track history by dipping under 10 seconds (9.9). Hines did it first but both were credited with the record. At the 1968 Olympic Games, Greene was again bothered by injuries and was third in the 100. Despite the injury, he led off the U.S. 4 x 100-meters relay team that won the gold medal and set a world record. Following his athletic career, Greene became a career army officer, serving as sprint coach at West Point and head coach of the All-Army team. After retiring with the rank of major, he became a director for Special Olympics International and is still active in the sport.
