With four other men whose interest he obtained, Roosevelt formed the Georgia Warm Springs Foundation, a non-stock, non-profit center for after-care of poliomyelitis at Warm Springs, in Meriwether County, Georgia. In 1926, Roosevelt bought the property that would eventually house the Georgia Warm Springs Foundation and began to create and design the first modern treatment center for infantile paralysis in the country. Roosevelt and architect Henry J. Toombs designed a new pool complex featuring an indoor pool, a play pool, and an exercise pool. The Georgia Hall was built soon after as a part of the new polio treatment center, using money donated by average Georgians.
