The architects William Schickel and Isaac Ditmars, both of German heritage, were known as Catholic architects who built a large number of churches including St. Ignatius of Loyola, St. Francis, St. Vincent, St. Monica, and St. Joseph. They also built a large number of hospitals, large business buildings, and private residences in New York City. Schickel went into a partnership with the Canadian-born Isaac Edward Ditmars in 1885 and together they specialized in ecclesiastical and institutional buildings.
