“In 1892, Sullivan developed his magnum opus, the Wainwright Tomb, a monument dedicated to the memory of Charlotte Dickson Wainwright, in Bellefontaine Cemetery, St. Louis. This building is not only listed on the National Register of Historic Places, but it is also a St. Louis Landmark. In 1893, Sullivan began designing his iconic polychrome modern Transportation Building for the “White City”, at the World’s Columbian Exposition in Chicago. The iconic duo of partners broke up in 1893, due to the severe economic depression that took over America, and Sullivan began encountering serious financial difficulties, and he gave into alcoholism.”
