Hilary "Harry" Douglas Clark Pepler TOSD (1878–1951) was an English printer, writer and poet.
[5] Pepler became deeply involved in the aesthetic of the Arts and Crafts Movement and the politics of Fabianism.
He became friends with Edward Johnston and, during World War I, met Eric Gill through the Hampshire House Workshops.
In 1915, Pepler moved to Ditchling, where Gill had set up a commune of religious artists and artisans.
There, he founded St. Dominic's Press, with the intention of printing books “about crafts which machinery threatened with extinction.”[7] It published, amongst other books, important editions for the Ulysses Bookshop in High Holborn, London, owned by Jacob Schwartz, to 1937.
