The White Fathers acquired the Stony Wold Sanatorium as a place to train missionaries for work in Africa. They also held a family summer camp called Camp Lavigerie on the property. The site is now part of the New York State Forest Preserve.
From a message board on the web: The chapel building near Lake Kushaqua is the only remaining building. It has been the community hall and chapel and movie theater for the Tuberculosis treatment center and has been the chapel for the "White Fathers" (medical missionaries to Africa, originally from France and known for their white robes). The White Father's Tiffany windows are now installed at the New-York Historical Society Museum at Central Park West and 77th Street. They are on the stair landing outside the third floor.
There are lots of links to Camp Lavigerie.
