Sir Humphrey Sumner Milford (8 February 1877 – 6 September 1952) was an English publisher and editor who from 1913 to 1945 was publisher to the University of Oxford and head of the London operations of Oxford University Press (OUP).
In his work, he made OUP a major worldwide publisher of noteworthy books, music, and educational material for the general public,[1] complementing the scholarly work of the Clarendon Press in Oxford.
Upon publication of the final volume of the Oxford English Dictionary in 1928, he was among those awarded an honorary D.Litt.
His sister Violet Alice Milford was the mother of the poet and scholar Anne Ridler (1912–2001).
In summing up his work, The Times of London cited his "unfailing catholicity", "nose for a good book", and "rare sense of the practicable".
