“Mrs B. Lewis” was the pseudonym used by **Dorothy Taylor** (1911–2009) for entering crossword competitions:
> Dorothy used to enter competitions under the pseudonym Mrs B Lewis, which was the maiden name of her sister-in-law. One of her fellow crossword compilers and solvers was Colin Dexter, the author of the Inspector Morse detective novels, and when he came to name the characters in his books he often drew on the names of his crossword colleagues. Dorothy was one of his favourite compilers and he named Morse’s Sergeant Lewis after her.

Dorothy Taylor compiled the "Everyman" crossword in _The Observer_ from 1963 to 1993. _The Observer_ is weekly, and she alternated with co-compiler Alec Robins, so that she set about 780 crosswords for the newspaper.
