7/21/1923 Charles Goodrum checks in

July 21, 1923.  Charles A. Goodrum was born on this date.  He became the Director of Research at the Library of Congress's Congressional Research Service (the collection of experts that answered reference questions only for the members of Congress).  He wrote one of the first  series of mysteries with a library-background, whose titles were usually awful puns like Carnage of the Realm, The Best Cellar, and, well, see illustration.
