Eric Lemming was nineteen years old when he set a world record of 49.31m in the javelin throw in 1899. Unfortunately, the javelin was not included in the program of the 1900 Olympics, but Lemming traveled to Paris anyway and took part in six events, placing fourth in the high jump, the pole vault and the hammer throw and eighth in the discus throw.
The javelin throw was finally accepted as an Olympic event in 1908, at which time Lemming was still the world record holder. Lemming won the freestyle javelin event (after which it was dropped from the program) and then set another world record (54.825m) in winning the regular javelin event by more than four metres. He also placed eighth in the hammer throw and participated in the discus throw and the Greek-style discus throw.
At the age of 32, Lemming made a final appearance at the 1912 Olympics, which were held in his home country of Sweden. Lemming rose to the occasion, earning the gold medal by making the first javelin throw to exceed 60m, a feat that led the appreciative crowd to give him a standing ovation.
Later in the Stockholm Games, he placed fourth in a one-time event in which the competitors threw the javelin with each hand, and he competed in a similar event with the discus. During his career, Lemming set ten javelin world records, culminating in a 1912 post-Olympic throw of 62.32m.
