W. O. (Will O.) Rigby

Published in Topeka, Kansas, W. O. Rigby is credited as the author of Rigby’s Reliable Candy Teacher and Soda and Ice Cream Formulas, a confectionery handbook issued in the early 20th century. Library of Congress records list the 1909 edition, and later editions were expanded and associated with Fred Rigby as well, suggesting the book had an ongoing life beyond its first release.

The surviving record points to Rigby less as a literary figure than as a practical trade writer. His work focuses on candy making, sodas, ice cream, and shop methods, and it earned a lasting place among historical food and confectionery references because of its hands-on, professional tone.

Reliable biographical details about his personal life are limited in the sources I could confirm here, so it is safest to remember him mainly through the book that carries his name and through his connection to Topeka’s confectionery trade.
