William F. (William Franklyn) Hudgings

William F. Hudgings, listed by Project Gutenberg as William Franklyn Hudgings (1889–1937?), is credited with the short popular science work Introduction to Einstein, originally published in 1923 as part of the Haldeman-Julius Little Blue Book series. That booklet set out to explain relativity in simple, non-technical terms for everyday readers.

Library and audiobook records suggest this is the work for which he is chiefly remembered. Project Gutenberg currently lists Introduction to Einstein as his only book there, and LibriVox also identifies him through that title.

Some catalog and memorial records give more personal details, including a birth date of October 24, 1889, in Missouri and a death date of October 17, 1937, in Brooklyn, New York. Because easily confirmed biographical information is limited and scattered, he remains a somewhat elusive figure—known less for a large body of writing than for one compact effort to make modern physics understandable.
