YMCA Century of Group Swimming

In 2006, America’s 2,617 YMCAs celebrate 100 years of group swimming instruction. Long known for their expertise in providing swim instruction and aquatics programming to all generations, YMCAs have introduced tens of millions of people nationwide to swimming since inventing group swim instruction in 1906.

The first reported YMCA “swimming bath” was built in New York City at the Brooklyn Central YMCA in 1885. The Brooklyn YMCA pool was 14 feet wide by 45 feet long and 5 feet deep. Early pools, in addition to being small, had no filters or recirculation systems so water in the pool became dirtier until the pool was drained and cleaned, which some Ys did on a weekly basis.

In the early 1900s, instructors suspended aspiring swimmers in the water with ropes and pulleys attached to the ceiling—until George Corsan, an instructor at the Detroit YMCA, introduced group swimming instruction in 1906. Corsan’s revolutionary approach allowed large groups to practice their swimming stroke on the land and gain confidence before practicing in the water.

In 1909, the YMCA in Kansas City, Mo., introduced a new type of a pool with roll-out rims and a water recirculation system. In 1910, the YMCA invented a water filtration system, creating a healthier atmosphere for swimmers and, in turn, making swimming pools more appealing to the public.

The combination of Corsan’s group-teaching techniques and new filtration systems popularized swimming and swim instruction at YMCAs. In 1910, the YMCA launched the first Teaching America to Swim campaign, which aimed to, “teach every boy and young man in North America, who does not know how, to swim.” 

By 1932, more than a million boys and men a year enjoyed their time swimming at YMCAs. In 1956, the YMCA introduced Learn to Swim Month. By 1984, YMCAs collectively became the largest operator of swimming pools in the world. Today, millions of boys and girls, men and women of all races and faiths have learned to swim at YMCAs in the United States and around the world.

In addition to teaching millions of Americans to swim, the YMCA movement has had a huge impact on swimming instruction and aquatics programming in general. In the early 1900s, the YMCA encouraged the Red Cross to include lifesaving instruction in its disaster and wartime services programs. The Easter Union YMCA invented the first mobile swimming pool in 1961, enabling the Y to take swim instruction and aquatics programs to those who could not visit the YMCA. In both World Wars I and II, the U.S. military used YMCA swim instruction techniques to train the Army, saving thousands of lives. In 1943, the chairman of the YMCA National Aquatic Committee published Warfare Aquatics, widely used by the Armed Forces and YMCAs during World War II and beyond.

YMCAs are world pioneers in swimming instruction and aquatics programs, and the place where Americans go to find the most trusted instructors of swimming and lifeguard training. Providing introductory and advanced swimming, water fitness classes and competitive swimming programs for youth and adults, YMCAs are widely recognized as America’s leading resource in aquatics. At YMCAs, children and adults learn not only how to swim, but also about leadership, safety and rescue skills, and water activities that can be enjoyed for a lifetime.
