The leaders of the Roman Catholics of St. Louis have been bishops, archbishops and Cardinals.
Two notable leaders celebrated their installations on Oct. 8. In 1847, Peter Richard Kenrick was ordained as the first Archbishop of St. Louis, then 99 years later, Joseph Ritter was installed as the fourth Archbishop of St. Louis.
