Lloyd Jacquet was born in Brooklyn to a father who had emigrated from France. After serving as a colonel in World War I, Jacquet worked as an editor for Major Malcolm Wheeler-Nicholson's National Allied Magazines (the future DC Comics) on some of the first comic books — including the landmark "New Fun: The Big Comic Magazine" (Feb. 1935), the first such publication with solely original material rather than any newspaper comic strip reprints. Jacquet remained through its first four issues, later becoming art director of the George Matthew Adams Service in c. 1936–1937, and then art director of Centaur Publications — where some sources credit him with co-creating writer-artist Bill Everett's superhero Amazing Man — before leaving to start Funnies, Inc.
