Harry E. Sheldon Calvary Camp was founded in 1936. May Sheldon — the widow of Harry E. Sheldon, founding partner of then Allegheny Steel — donated the land to establish Sheldon Calvary Camp in memory of her late husband.

Much has changed at Calvary Camp since. What began as a camp for choir boys from Calvary Church in Pittsburgh became full and separate overnight camps for boys and girls, and then evolved into a unified, coeducational overnight camp (still often referred to as “coed camp”). Adjacent land has been purchased, and buildings and swimming pools have been built and upgraded. Program offerings have been adapted, let go, or added. Names and faces — and camp fashions — have shifted with the generations. Yet, the essence of Calvary Camp remains the same.
