author
A little-known writer with a foot in both classic science fiction and modern ebook publishing, this author is best known here for Jack of No Trades. The record that survives online is sparse, which gives the work an extra air of discovery.

by Charles Cottrell
Available publisher and catalog records suggest Charles Cottrell is the author of Jack of No Trades, which appears on Simon & Schuster's author page and book listings.
Science fiction bibliography records also connect the name Charles Cottrell, writing as C. L. Cottrell, with the 1959 novelette Danger! Child at Large in Star Science Fiction Stories No. 6. Because the online trail is thin, it's hard to say with confidence how much biographical detail is publicly documented beyond the works themselves.
That makes this one of those authors best approached through the writing first: a name that surfaces in bibliographies and publisher catalogs, leaving readers to piece together the rest from the stories.
