Duke Paoa Kahinu Mokoe Hulikohola Kahanamoku was a Hawaiian competition swimmer who popularized the sport of surfing. A Native Hawaiian, he was born to a minor noble family less than three years before the overthrow of the Hawaiian Kingdom. He lived to see the territory's admission as a state, and became a United States citizen. He was a five-time Olympic medalist in swimming, winning medals in 1912, 1920 and 1924.

Surfing is a surface water sport in which an individual, a surfer, uses a board to ride on the forward section, or face, of a moving wave of water, which usually carries the surfer towards the shore. Waves suitable for surfing are primarily found on ocean shores, but can also be found in standing waves in the open ocean, in lakes, in rivers in the form of a tidal bore, or in wave pools.
