The Outdoor Recreation League was founded in 1898 to provide for "proper and sufficient exercise and recreation places, playgrounds, and open air gymnasiums for the people." Byron captured the success of the Hudson-Bank Gymnasium, located within the new DeWitt Clinton Park between 11th and 12th Avenues and 52nd and 54th Streets, during its inaugural year in several photographs that document constructive play and exercise in this notoriously dangerous Hell's Kitchen neighborhood.
