Frank Reynolds was born in London as the son of an artist. He studied at Heatherley's, and during the 1890s, he began to contribute to periodicals like Judy, Longbow, Pick-me-up and Playgoer. He made cover illustrations for Sketchy Bits, and did full-page humorous drawing in the Sketch. He was a member of the London Sketch Club, and later also joined the Royal Institute of Painters in Water-Colour. He became known for his watercolor illustrations for novels by Dickens in 1910-12. A contributor to Punch from 1906, Reynolds joined the staff in 1919 and, a year later, succeeded his brother-in-law, F. H. Townsend, as art editor, a post he retained for over a decade. In 1933, he moved to Thames Ditton, apparently to retire. However, he continued to illustrate throughout the 1930s and into World War II. Among his most popular creations are 'The Bristlewoods'.
