Samuel Dutton Walker (1833 - 15 June 1885) F.S.A. was an architect based in Nottingham.
On 23 January 1862 he married Elizabeth Rebekah Oldershaw at St James' Church, Standard Hill.
Two of his pupils, Arthur Brewill and Arthur George Marshall went on to have successful careers as architects in the Nottingham area. In 1879 he went into partnership with John Howitt, as Walker and Howitt, and this partnership lasted until Walker’s death in 1885. They established themselves in a practice in Severn Chambers, 10 Middle Pavement, Nottingham.
He was involved with the Nottingham School of Art and two scholarships were founded through his connection with it, one which enabled the holder to study church architecture abroad.
He died on 15 June 1885 and left an estate valued at £13,945 2s. 2d. (equivalent to £1,358,400 in 2015).
