Today's Google Doodle is a dedication to Hawaiian-American competition swimmer, Duke Kahanamoku. He was a five-time Olympic medalist in swimming.

He was also an actor, lawman, beach volleyball player, and businessman credited with spreading the sport of surfing.

Kahanamoku had qualified for the US Olympic swimming team in 1912. At the Summer Olympics in Stockholm that year, he won a gold medal in the 100-meter freestyle, and a silver medal in the men's 4x200-meter freestyle relay.

He finished the 100 meters with a silver medal during the 1924 Olympics in Paris. At age 34, this was Kahanamoku's last Olympic medal. He also was an alternate for the US water polo team at the 1932 Summer Olympics.
