Many of the photographs from Bellefontaine Cemetery deal with ideas that I have been pursuing in other work over the years. The primary area being investigated here is the one of time. How objects and life change in this fourth dimension seemed a very interesting way to approach Bellefontaine. In working I found that one way to communicate this concept with the two dimensional photograph was to work in series.

Robert Pettus's photographs are in the collections of the Museum of Modern Art, the Library of Congress, and the St. Louis Art Museum, among others, and are featured in the book "Movers and Shakers, Scalawags and Suffragettes: Tales from Bellefontaine Cemetery," published in 2008 by the Missouri History Museum.
