Nestled in the heart of Paris, the American Cathedral of the Holy Trinity today stands as one of the great buildings of this ancient city. The history of the church itself presents a rich portrait of lively men and women who made it their mission to serve God and the people of Paris with all their hearts. Meticulously researched, A History of the American Pro-Cathedral Church of the Holy Trinity, Paris, 1815-1980 delivers an impressive narrative on each period of growth and development within this church. Beginning with the American Episcopal Church's need to serve Americans living in Paris, author Cameron Allen traces the development of the foundational congregation, the building of the first church, and its organization over the years. Allen draws on diary entries, church documents, and other primary sources to reveal the personalities behind church leaders, including W. O. Lamson, who formally established the church, the pivotal role of J. P. Morgan, organist L. K. Whipp, and German Colonel Rudolph Damrath, a Lutheran minister who took over during the German Occupation of France during World War II. In addition, he discusses the church's role during major historical events and its present needs. This inspiring, well-written history provides an excellent resource for current and past church members, rectory libraries, and historians.
