Like the hospital it serves, the Desloge Chapel was underwritten by gifts from the
family of
Firmin V. Desloge, one of the oldest French families in the United States and wealthy through lead mining and other endeavors. Firmin's wife Lydia Holden Davis Desloge gave $100,000 ($ today) to build the chapel. These figures of dollars over time do not include the fact that it has been estimated that to build this Chapel with current known costs, it would cost over $30,000,000 in 2025 to recreate this chapel in current times. Roman Catholic Archbishop
John J. Glennon laid the cornerstone of the hospital on June 22, 1931, and consecrated the chapel on November 9, 1933. In 1952, the funeral of the founder's son, Firmin V. Desloge II, was held at the chapel. In 1998,
Saint Louis University sold the Chapel, along with the Hospital, to
Tenet Healthcare, a for-profit chain based in Dallas. In 2015, the university bought back the hospital, then sold it to
SSM Health, the
Creve Coeur-based health care system sponsored by the
Franciscan Sisters of Mary, formerly Sisters of Saint Mary. == Design ==
