Purcell & Elmslie (P&E) was the most widely known iteration of a progressive American architectural practice.
P&E was the second most commissioned firm of the Prairie School, after Frank Lloyd Wright.
[2] The architects were commissioned for work in twenty-two states, participated in the competition for the National Parliament Buildings in Canberra, Australia, and prepared plans for a large institutional church, or Y.M.C.A., in Hunan, China.
The two principals of the firm, William Gray Purcell (1880–1965) and George Grant Elmslie (1869–1952) both eventually received Fellowships in the College of the American Institute of Architects.
[1] A number of works by each of the partnerships are listed on the National Register of Historic Places.
