Kenneth Frederic Ernst (1918–1985), known professionally as Ken Ernst, was an US comic book and comic strip artist. He is most notable for his work on the popular and long-running comic strip Mary Worth from 1942 to 1985. With his realistic style, uncommon in those early years, Ernst paved the way for soap opera strips that followed.
Ken Ernst was born in 1918 in Illinois. At the age of 12, he was elected President of the Chicago Chapter of the International Brotherhood of Magicians. Ernst began his working life as a stage magician, but he aimed for a career in art. Using money made performing magic to finance his education, he studied at the Art Institute of Chicago and the Chicago Academy of Fine Arts.
In 1936, Ernst began his art career during the burgeoning Golden Age of Comic Books. He joined the Harry "A" Chesler comic book production shop, where he contributed to Star Comics and Funny Pages until 1943. He took assignments on numerous titles from Centaur in the late 1930s. Ernst also worked for National Periodical Publications on Larry Steele and at Western Publishing on Buck Jones, Tom Mix and Clyde Beatty. He is credited with the art on back-up stories in the DC Comics flagship title Detective Comics, issues 31-33, 38, and most issues between 39 and 49.
Ernst's artwork appeared in comic books again in the late 1940s and early 1950s in The Green Hornet from Harvey Comics, but the panels were reprints of his Mary Worth.
It was in the field of newspaper comics, however, that Ken Ernst became famous. Between 1940 and 1942, he assisted on the daily Don Winslow of the Navy strip. (Another source reports that he "ghosted" that strip).
