The discus dates back to the ancient Olympics. Made of metal and varying in size and weight, the discus was thrown back then using a technique similar to that of today's athletes. The first modern Olympic winner in the discus was an American college student, Robert Garrett, who was actually a shot putter from Princeton. He had never seen a discus before the Olympics, but his performance was good enough to defeat the Greek champion's in 1896. The greatest Olympic discus thrower is American Al Oerter, who won Gold in four straight Olympics, from 1956 to 1968, each time setting a new Olympic record. In each of his 4 Olympic appearances, Oerter was never the world record holder or the favorite to win the event. Despite agonizing injuries in Tokyo -- he had a slipped disc, torn rib cartilage and was bleeding internally -- he threw for the Gold and broke the Olympic record on his final attempt, for a third Gold medal. He went on to win a fourth, at the age of 32, in Mexico City in 1968. Al Oerter is the only athlete to ever win 4 consecutive Gold medals in the same event in track & field.
