The Hadfield firm was and is one of the major Sheffield architectural practices, and one of the longest lived: it now has around eighty professional staff, and, while still based in Sheffield, undertakes commissions far beyond it. Like other such practices, it has had different names according to its partners at any given time. Ruth Harman and John Minnis give a very helpful summary of these changes during the Victorian period:
The Hadfield firm: John Grey Weightman (1801-72); 1838-50 Weightman & (Matthew Ellison) Hadfield (1812-85); 1850-60 George Goldie (1828-87), a partner in the practice; 1864-90 M.E. Hadfield & Son (Charles Hadfield (1840-1916); 1890-9 Hadfield Son & Garland; 1899-1916 C. & Charles Matthew Ellison Hadfield (1867-1949); 1916-24 C.M.E. Hadfield; 1924-35 C.M.E. Hadfield & Robert Cawkwell (1894-1968); 1946-63 Hadfield Cawkwell & Davidson; since 1963 Hadfield Cawkwell Davidson & Partners. 
Note that on the firm's current website, Matthew Ellison Hadfield is credited with having founded the firm in 1838. As shown, the Hadfield name has continued into the twentieth and twenty-first centuries. The firm is now known as Hadfield Cawkwell Davidson. — JB
