INDIANAPOLIS -- Bobby Morrow, a three-time Olympic gold medalist at the 1956 Games, died on Saturday at the age of 84. Morrow's family said he died of natural causes at home in San Benito, Texas. The top sprinter of the middle 1950s, Bobby Morrow came from a small Texas college to emerge as one of the stars of the 1956 Melbourne Olympic Games. As a student at Abilene Christian, Morrow first attracted notice in 1955 when he won the AAU 100-yard dash title. The next year was his greatest. He started off by taking the national collegiate 100-200 sprint double, then won the AAU 100 for the second straight year. In Melbourne, he won three gold medals, taking the 100m and 200m and anchoring the winning 4x100m relay team. Following the Games, he was honored as "Sportsman of the Year" by Sports Illustrated. His success continued in 1957 when he repeated the national collegiate sprint double, also winning the Sullivan Award as the nation's top amateur athlete. In 1958, he took the AAU sprint double, the last major titles he won. Morrow tied the world records in the 100 and 200 six times (three times in each) and also ran on Abilene Christian quartets that set world records in the 4x110-yard and 4x220-yard relays in 1958. His duels with fellow Hall of Famer Dave Sime were some of the greatest in sprint history. Morrow made a comeback in 1960 and barely missed making the Olympic team. He starred in track and football at San Benito High School, where the football stadium is named Bobby Morrow Stadium. Morrow was elected to the U.S. National Track & Field Hall of Fame in 1975 and the U.S. Olympic Hall of Fame in 1989.
