James Edward Murphy Jr. (November 20, 1891 – March 9, 1965) was a self-taught American cartoonist who is best known for his long-run family comic strip, Toots and Casper. His earliest strips, signed J.E. Murphy, had a crude awkward look, but as his cartooning improved, his full signature of Jimmy Murphy appeared.
Born in Chicago, Murphy grew up in Omaha, Nebraska. When he was 15 he began selling political cartoons to the local newspapers, including the Omaha Examiner. He briefly attended Creighton University in Omaha, but he left home in 1910, spending the next eight years drawing political cartoons for the Inland Herald (Spokane, Washington), the Oregon Journal (Portland, Oregon) and the San Francisco Call & Post.
