The American Environmental Photographs collection consists of 4,500 photographs documenting natural environments, ecologies, and plant communities in the United States at the end of the nineteenth and the beginning of the twentieth century.
The photographs in the collection were created between 1891 and 1936 by faculty members and students in the Department of Botany of the University of Chicago. The research and field studies of these Chicago botanists, including Henry Chandler Cowles (1869-1939) and George Damon Fuller (1869-1961), are considered to be among the most influential contributions to the development of modern ecological studies.
