Harry Kemelman (1908–1996) was best known for his popular rabbinical mystery series featuring the amateur sleuth Rabbi David Small. Kemelman wrote twelve novels in the series, the first of which, Friday the Rabbi Slept Late, won the Edgar Award for Best First Novel. This book was also adapted as an NBC made-for-TV movie, and the Rabbi Small Mysteries were the inspiration for the NBC television show Lanigan’s Rabbi. Kemelman’s novels garnered praise for their unique combination of mystery and Judaism, and with Rabbi Small, the author created a protagonist who played a part-time detective with wit and charm. Kemelman also wrote a series of short stories about Nicky Welt, a college professor who used logic to solve crimes, which were published in a collection entitled The Nine Mile Walk.

Aside from being an award-winning novelist, Kemelman, originally from Boston, was also an English professor.
