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.^[1] The firm in all iterations was active from 1907 to 1921, with their most famous work being done between 1913 and 1921.^[1]

The firms consisted of three partnerships: Purcell and Feick (1907–10); Purcell, Feick, and Elmslie (1910–12), and Purcell and Elmslie (1913–21). Elmslie had joined the Minneapolis-based firm in 1907, at the request of Purcell.^[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] George Feick Jr. who was son of George Feick, an Ohio contractor, was the original partner with Purcell. Purcell and Feick had been students together at Cornell University. They rejoined to tour in Europe together during 1906-1907 and then came to Minneapolis to open their partnership. The firm had offices in Chicago, Philadelphia, and Minneapolis.^[1] A number of works by each of the partnerships are listed on the National Register of Historic Places.^[3]
