Harper, Leonard Ewen 1886 - 1954

Leonard Ewen Harper was born in Kings Norton, Worcestershire, England on 13 May 1886 and was the son of the architect Ewen Harper (1853-1920). He is presumed to have trained as an architect at his father's practice Ewen & J. Alfred Harper in Birmingham.  When his father retired in 1919, he became a partner in the practice which continued as Ewen Harper, Brother & Co.

Leonard Ewen Harper was elected a Fellow of the Royal Institute of British Architects (FRIBA) in 1925.

The dissolution of Ewen Harper, Brother & Co. was announced in The London Gazette, 5 October 1937 p.6177 and it was stated that "Leonard Ewen Harper  F.R.I.B.A. will continue to practise for commercial and other work under the old firm name of 'Ewen Harper Brother & Co.' at  Ruskin Chambers 191 Corporation Street Birmingham as heretofore, who will shortly take into partnership his Sons Bernard Ivan Harper and Dennis Rosslyn Harper. James Alfred Henry Harper (the Senior Partner in the old firm) and his Son Walter Geoffrey Harper will continue to practise from the 30th September at Union Chambers, Temple Row, Birmingham under the style of 'J. Alfred  Harper & Son.'"

By the early 1950s Leonard Ewen Harper's practice had been renamed Ewen Harper & Co. with his sons, Bernard Ivan Harper (1914–1977) and Dennis Rosslyn Harper (1915–2001) as partners, with an office at Ruskin Chambers, Corporation Street, Birmingham.  This partnership was dissolved in 1952.

Leonard Ewen Harper's address was given as "Bloemfontein:, Barnt Green, Worcestershire in 1911 and Great Hytall, Lovelace Avenue, Widney Manor, Solihull, Warwickshire, England in 1939 and 1954. He died in Birmingham on 7 January 1954
