About the author

William D. O'Brien was a Roman Catholic priest who later became an auxiliary bishop in Chicago. Archival records from Loyola University Chicago identify William D. O'Brien, D.D., as born in Chicago in 1878, ordained in 1903, and closely involved with the Catholic Church Extension Society, eventually serving as its president.

As an author, he is associated with Life of the Blessed Virgin in Pictures, published by Extension Press in 1919. The book suggests the same practical, reader-friendly approach that shaped much of the Extension Society's mission: bringing Catholic teaching and devotion to a broad audience in an appealing, understandable form.

The available sources are limited, but they consistently point to a life spent in service to the Church through both leadership and religious publishing. That combination gives his work a distinctive place for listeners interested in devotional writing from early twentieth-century American Catholic life.
