I was thinking of Sir Arthur Conan Doyle and Sherlock Holmes, but his was a paraphrase of Occam's Razor. Snippet via Wiki:

"The fictional friar, William of Baskerville, alludes both to the fictional sleuth Sherlock Holmes and to William of Ockham. The name itself is derived from William of Ockham and Sir Arthur Conan Doyle's book The Hound of the Baskervilles. William of Ockham, who lived during the time of the novel, first put forward the principle known as "Ockham's Razor": often summarised as the dictum that one should always accept as most likely the simplest explanation that accounts for all the facts (a method used by William of Baskerville in the novel), similar to Sherlock Holmes' familiar assertion that when one has eliminated the impossible, whatever remains â?? however improbable â?? must be the truth."

I like the Sherlock Holmes quote the best, but they say basically the same thing, and Sir Arthur Conan Doyle obviously did get it from William of Ockham.
