Al Wiseman worked in the advertising field, before he was assigned by Hank Ketcham to do the 'Dennis the Menace' comic book. The daily 'Dennis' strip was a big hit, so a series of comic books followed. Wiseman and writer Fred Tool worked on the comic from 1953 to the 1960s. While at first attempting to copy Ketcham's style, Wiseman soon developed his own individual style. Wiseman has also worked on George Crenshaw's 'Belvedere' panel, and on the 'Yogi Bear' newspaper strip.
