Thorpe threw himself into sports and became a star in football and track. He was known for his speed and strength.
Thorpe did so well he went to the 1912 Olympics in Sweden, a country in Europe. He became the first Native American to win a gold medal for the United States. One of his two gold medals was for the decathlon, which has 10 track and field events.
Many people think winning the decathlon is a top honor. The king of Sweden told Thorpe, “Sir, you are the greatest athlete in the world.”
