On June 23, 2012, the National Railroad Hall of Fame in Galesburg, Illinois, inducted John Walker Barriger III (1899-1976) into its pantheon of leaders in honor of his myriad contributions to the industry. Barriger III achieved high acclaim for his leadership of federal transportation agencies and of railroads themselves. Unusually for a top executive, one of the tools Barriger III used in making decisions and prophesies was none other than photographs he made himself of railroad infrastructure. So successful was he in helping to cure the industry from the 1920s into the 1970s that he became known as “the doctor of sick railroads.” And now at least some of the 60,000 diagnostic railroad photographs he made, both for his own pleasure and as x-rays of the industry, can be considered more than tools. They can be considered art. The Center, the Hall, and the John W. Barriger III National Railroad Library in St. Louis presented an exhibition of Barriger’s photography at the Ford Center for the Fine Arts at Knox College in Galesburg over the summer. The exhibition will appear in the future at the Barriger Library.
