Treadwell, Henry John (1861–1910). English architect. With Leonard Martin (1869–1935) he practised in London from 1890 to 1910, specializing in developing small, narrow-fronted sites in London's West End. Stylistically, their work was an eclectic mix of
Art Nouveau,
Baroque, late-Continental
Gothic, and dashes of other styles, used in a very free way. Among their best buildings are 23 Woodstock Street, 7 Dering Street, 7 Hanover Street, 74 New Bond Street, 20 Conduit Street, 78 Wigmore Street, 106 Jermyn Street, and 61 St James's Street (all early 1900s), and 78–81 Fetter Lane, in the City. They designed the
Rising Sun Public House, 46 Tottenham Court Road (1897), St John's Hospital, Lisle Street, Leicester Square (1904), the
White Hart, Windsor, Berks., and St John's Church, Herne Hill (1910).
