George Putnam Washburn (March 21, 1846 – May 16, 1922) was a prominent architect practicing in Kansas. Washburn came to Kansas in 1870, worked as a carpenter and architect, and in 1882 opened an architecture practice in Ottawa, Kansas. His son joined his firm which became George P. Washburn & Son. In 1910 George P.'s son-in-law, Roy Stookey, joined the firm, and George P. retired. After George P. died in 1922 the firm became Washburn & Stookey. Washburn designed nine Carnegie library buildings in Kansas, and is most known for the 13 courthouses he designed. A number of his buildings are listed on the U.S. National Register of Historic Places, with several of the libraries being listed under one study.
