Dorothy Kostuch was a longtime instructor of art history at the College for Creative Studies in Detroit (formerly the Center for Creative Studies), who died in 2005 after a long battle with cancer. Kostuch received a PhD in art history from Columbia University and traveled extensively through Europe to visit architecturally significant buildings. Her expertise in art history and medieval architecture led her to teach a course on historic Detroit churches and spawned the beginnings of this book project.
