author
A little-known early 20th-century writer, remembered today mainly through public-domain editions of his work. Reliable biographical details appear to be very scarce, which gives his surviving books a bit of mystery.

by Charles Sheldon French
Charles Sheldon French is an obscure author whose works are preserved in public-domain catalogs, including Project Gutenberg and The Online Books Page. Those sources confirm his name and authorship, but they do not provide much in the way of personal history.
Because I couldn't confirm standard biographical details such as birth and death dates, hometown, or career background from reliable sources available here, it's best to describe him cautiously. He seems to be one of those writers whose books outlasted the record of the person behind them.
That limited paper trail can be part of the appeal for curious listeners: discovering an author through the work itself, without much biography getting in the way.
