Athletes with disabilities did compete in the Olympic Games prior to the advent of the Paralympics. The first athlete to do so was American gymnast George Eyser in 1904, he had one artificial leg.
Hungarian Karoly Takacs competed in shooting events in both the 1948 and 1952 Summer Olympics. He was a right-arm amputee and was able to shoot left-handed. Another disabled athlete to appear in the Olympics prior to the Paralympic Games was Liz Hartel, a Danish equestrian athlete who had contracted polio in 1943 and won a silver medal in the dressage event.
The first organized athletic event for disabled athletes that coincided with the Olympic Games took place on the day of the opening of the 1948 Summer Olympics in London, United Kingdom. Dr. Ludwig Guttmann of Stoke Mandeville Hospital,who had been helped to flee Nazi Germany by the Council for Assisting Refugee Academics (CARA) in 1939,hosted a sports competition for British World War II veteran patients with spinal cord injuries. The first games were called the 1948 International Wheelchair Games, and were intended to coincide with the 1948 Olympics.Dr. Guttman's aim was to create an elite sports competition for people with disabilities that would be equivalent to the Olympic Games.The games were held again at the same location in 1952, and Dutch veterans took part alongside the British, making it the first international competition of its kind. These early competitions, also known as the Stoke Mandeville Games, have been described as the precursors of the Paralympic Games.
