 Bragg was the last of the great pole vaulters to use an aluminum pole.From 1954 until 1960, he was always world ranked and capped a championship career in 1960 by setting a world record of 15' 9¼" (4.80 m) at the Olympic Trials and winning an Olympic gold medal with a vault of 15' 5" (4.70 m).He set a world indoor record of 15' 9½" (4.81 m) at Philadelphia in 1959 and, like Hall of Famer Cornelius Warmerdam, vaulted better indoors than outdoors.
