In 1973, David A. Walker, then a New York City Police Community Affairs Detective, developed the street game of Double Dutch into the World Class Sport that it is today. Since that initial tournament in 1974, competitive Double Dutch has expanded with citywide and national championships. Nearly 100,000 girls and boys representing schools and community centers throughout the United States and the world compete for team positions at the national and international events. The NDDL 33rd Annual, David A. Walker Memorial, Double Dutch Holiday Classic makes possible speed and music fusion events for the best Double Dutch teams in the world. Each year, since 1991, the Double Dutch Holiday Classic has sold out to parent supported, standing room only audiences.
