Glenn is a professor at the University of Florida. His book, Iron Muse: Photographing the Transcontinental Railroad, was published this spring by University of California Press. "Tracing the complex relationships and occasional conflict among photographer, publisher, and curator in crafting the photographs' different meanings over time, Willumson provides a comprehensive portrayal of the creation and evolution of an important slice of American visual culture" (from the book jacket). This is his second book. He lives with his wife, Peggy, in Gainesville, Florida, where he is the director of the Museum Studies Program, which confers a master's degree.
