Edmund Walter Wimperis was born in Brixton Surrey [now London] England on 10 February 1865. He was articled to his cousin John Thomas Wimperis (1829-1904) in London from 1882 to 1886 and remained with him as his assistant. He also attended classes at the Architectural Association in London. He qualified as an architect in 1889 and was elected an Associate of the Royal Institute of British Architects (ARIBA) later that year. From 1889 to c.1898 he worked as an assistant in the office of Wimperis & Arber in London.
Wimperis commenced practice as an architect in London, in the 1890s. He was in partnership with Hubert Springford East (1868-1947) in the 1890s and in c.1900 formed a partnership with John Reginald Best (1866-1950) as Wimperis & Best. The partnership was dissolved in c.1910 and in 1913 Wimperis formed a new partnership, Wimperis & Simpson, with William Begg Simpson (1880-1959). In 1925 Leonard Rome Guthrie (1880-1958) became a partner in the practice which was renamed Wimperis, Simpson & Guthrie. The firm had offices at 61 South Molton Street, London.
Wimperis was elected a Fellow of the Royal Institute of British Architects (FRIBA) in 1905. In 1910 he was appointed Surveyor to the Grosvenor Estate in London. He died in Uckfield, Sussex in December 1946
