This first critical biography of Msgr. Nelson Baker (Father Baker) places him within the rich context of American Catholic life between 1840 and 1940. Through his devotion to Mary under her title Our Lady of Victory he supervised an orphanage and Protectory for boys and an infant home for unwed mothers and their babies. As a result of more than 50 years of ministry, both as superintendent of these institutions and pastor of St. Patrick’s/Our Lady of Victory Parish, Baker became an almost iconic figure in western New York. Additionally, he was integrally involved in the Diocese of Buffalo, both as vicar general and twice administrator when the See was vacant. Nelson Baker’s work to date is relatively unknown outside western New York. This biography will broaden the base of people who know of his work and significant accomplishments for the betterment of children. His significant work in the institutions, and most especially his rather unique work with unwed mothers and their children, merits a precise, complete, and historically accurate account of his life.
