Having never met the Professor, I can't say how they would compare personality-wise, but about ten years ago, I edited a book for a fellow who had taken that job, and wound up working in Britain as a codebreaker during WWII. He eventually became a lawyer, but from his memoirs, during the war he was more interested in the young ladies he worked with and met while sightseeing than in codebreaking. Perhaps JRRT, being married, would have been able to give much more of his concentration to his work.
