b. 1857
Best known for a practical early-20th-century guide to interior design, this educator wrote about beauty, usefulness, and hands-on learning in a way that feels inviting rather than fussy.

by Charles Franklin Warner
Charles Franklin Warner, born in 1857, is credited as the author of The Library of Work and Play: Home Decoration. In that book, published by Doubleday, Page & Company, he presents home decoration as something ordinary people—and especially young learners—can study through making, planning, and careful observation.
The book identifies him as Prof. Charles F. Warner, Sc.D. and says he spent eight years as Master of the Rindge Manual Training School in Massachusetts. It also describes him as serving for twelve years as principal of the Technical High School and director of the Evening School of Trades in Springfield, Massachusetts.
That background helps explain the tone of his writing: practical, orderly, and strongly shaped by manual training and design education. Reliable biographical details beyond those basic career notes were not easy to confirm from the sources I found, so this overview stays close to the record that can be verified.
