The Duke wanted surfing in The Olympics.
The Duke's Olympic record (swimming for USA);
1912 - Stockholm -
Gold - 100m Free, and
Silver in 4x200m Free.
1916 - Berlin - Games were obviously cancelled
1920 - Antwerp -
2 x Gold - 100m Free and 4x200m Free
1924 - Paris -
Silver - 100m Free
There's little doubt he would have won Gold in Berlin. He was paddling heavy solid redwood boards in the surf for training!
