Harold Teen is a discontinued, long-running American comic strip written and drawn by Carl Ed (pronounced "eed"). Publisher Joseph Medill Patterson may have suggested and certainly approved the strip's concept, loosely based on Booth Tarkington's successful novel Seventeen. The strip ran from 1919 to 1959. Asked in the late 1930s why he had started the strip, Ed answered, "Twenty years ago, there was no comic strip on adolescence. I thought every well-balanced comic sheet should have one."
