Answer:
In 1973, David A. Walker, then a New York City Police Community Affairs Detective, joined by his partner Detective Ulysses Williams, developed the street game of Double Dutch into the World Class Sport that it is today. With the assistance of the physical education instructors at IS 10, Walker and Williams revitalized the game by developing it into a competitive team sport. On February 14, 1974, the first Double Dutch tournament was held with nearly 600 fifth, sixth, seventh and eight grade students participating.
