Boys Jumping on a Trampoline at the National Asthma Center, between 1974-1979

Two boys jump on a trampoline at the National Asthma Center (NAC) in Denver, Colorado. The NAC encouraged asthmatic children to participate in physical activities. These boys were patients of the NAC. The NAC's history began in 1907, when it was a refuge for lower-income children whose parents were being treated for tuberculosis, or had passed away from tuberculosis. At that time it was known as the Denver Sheltering Home. In 1928 the institution changed names to the National Home for Jewish Children in Denver. In 1953, the name changed to the Jewish National Home for Asthmatic Children at Denver and the institution became a treatment center for children with asthma. In 1957, the name changed again, to the Children's Asthma Research Institute and Hospital (CARIH). In 1973, the name National Asthma Center was adopted and in 1978 the National Asthma Center merged with the National Jewish Health Hospital and Research Center to become the National Jewish Health Hospital/National Asthma Center (NJH/NAC).
