Reed and Wright...
Funny you should ask this, Steven, just after I re-read Dave Hand's book "Memoirs." When Hand got the job of creating an animation studio for J. Arthur Rank (later known as Gaumont British Animation), he found he needed trained, skilled artists to teach the rather untrained British ones, and he chose Ralph Wright for story, Ray Patterson for animation and John Reed for effect animation. Patterson returned Stateside after a year, Wright stayed longer, and, yes, John Franklin Reed (1908-1992) remained after all others had gone "home," to become the animation director on Halas & Batchelor's 1954 release "Animal Farm." It seems he animated for Disney on - among other films - Paul Bunyan (1958) after that.
The book "Memoirs" has a funny anecdote in it told by Hand's secretary, the first person Hand hired, who later married animator Stan Pearsall. She tells of the time Ralph Wright and John Reed arrived at their hotel and she was to fetch them, only knowing that one was tall and the other wasn't. She walked up to two gents who fit the bill and asked "Are you Mr. Reed and Wright?" to which the answer was "No, we are Mr. Walk and Talk!" She had addressed the wrong two American gentlemen.
The fourth American drafted to work for GBA by Hand was none other than technical wizard Bill Garity, (according to the patent) the inventor of the click track, the Multiplane Camera, Fantasound, the Iron Pencil and the system Disney used for making 3D animation, but who - in Dave Hand's "Memoirs" - is only described as having stomach ulcer problems and always having to ingest powders against these.
