In 1876, Dr. Joseph Trimble Rothrock founded the North Mountain School of Physical Culture near Wilkes-Barre, Pennsylvania. For about $200, boys from Philadelphia and Wilkes-Barre came for four months over the summer. According to Dr. Rothrock, the idea was to take "weakly boys out into camp life in the woods . . . so that the pursuit of health could be combined with the practical knowledge outside usual academic lines."
