(Published in total by University Microfilms International, Ann Arbor, MI, 1968; in part by the Chicago Historical Society in BARRY BYRNE AND JOHN LLOYD WRIGHT: ARCHITECTURE AND DESIGN, 1982, with Ann Van Zanten.) The career of Barry Byrne began with his apprenticeship in the Oak Park Studio of Frank Lloyd Wright. After exposure to Wright's principles of organic architecture, Byrne transformed the teachings of his mentor into his own unique style. He retained many of the Prairie School principles in his works, and also absorbed influences from Louis Sullivan, Irving Gill, and European modernism. His major achievement was the integration of advanced liturgical views into ecclesiastical architecture. His wholly original designs integrated the nave and sanctuary spaces forty years before the reforms of Vatican II. Chappell's thorough and accurate account includes not only Byrne's buildings, but his insightful writings on architecture. There is a valuable list of all his built work, with dates and locations, in both the University Microfilm edition and the Chicago Historical Society catalog.
