An English-born American engraver, illustrator, and publisher of family periodicals.
He discovered he could accelerate the engraving process significantly by dividing a drawing into many small blocks and distributing the work among many engravers. A job on a large-format wood engraving which might have taken a month for a single wood engraver to complete, could be completed in a day by 30 engravers.
In 1853, he arrived in New York City to engrave woodcuts for P. T. Barnum's short-lived Illustrated News. After its failure, he began publishing the first of his many illustrated journalistic ventures, Frank Leslie's Ladies' Gazette of Fashion and Fancy Needlework, with good woodcuts by Leslie & Hooper, a partnership which dissolved in 1854.
The New York Journal soon followed, with Frank Leslie's Illustrated Newspaper (1855) (called Leslie's Weekly), The Boy's and Girl's Weekly, The Budget of Fun, and many others. Frank Leslie's Illustrated Newspaper, which included news as well as fiction, survived until 1922.
