Ben Cohen (1907–1971) was an author, publisher, and distributor of contract bridge books and stationery supplies. He pioneered duplicate bridge in the UK in the early 1930s and helped develop the Acol bidding system in the mid-1930s. He and the young Terence Reese wrote the first, and for a long time the only, textbook of the Acol system, The Acol Two Club (1938). He also contributed to newspapers and journals in South Africa, India, and Japan as well as the UK. Cohen was from Hove.
Cohen and Rhoda Barrow edited the European Bridge Players' Encyclopedia, published 1967 and based on the American Official Encyclopedia of Bridge (1964).
