Harold Hall "Doc" Keen OBE (1894–1973) was a British engineer who produced the engineering design, and oversaw the construction of, the British bombe, a codebreaking machine used in World War II to read German messages sent using the Enigma machine. He was known as "Doc" Keen because of his habit of carrying tools and paperwork in a case resembling a doctor's bag. After the war he was awarded the O.B.E.

rdfs:comment	Harold Hall Keen (* 1894 in London; † 1973 in Croxley Green), genannt „Doc Keen“, war ein britischer Ingenieur, der ab den 1930er-Jahren Chefingenieur der British Tabulating Machine Company (BTM) war und während des Zweiten Weltkriegs dort die Entwicklung und Herstellung der sogenannten Turing-Bombe leitete. Dabei handelte es sich um eine elektromechanische Entzifferungsmaschine, mit der den Briten der erfolgreiche Bruch der von den deutschen Militärs zur Verschlüsselung ihres geheimen Nachrichtenverkehrs eingesetzten Rotor-Schlüsselmaschine Enigma gelang. Seine Gewohnheit, Werkzeug und Unterlagen, wie Konstruktionszeichnungen, in einem auffälligen Arztkoffer mit sich zu tragen, brachte ihm den Spitznamen „Doc Keen“ ein.
