Today in the history of the American comic strip: December 13

American cartoonists and writers may not have invented the comic strip, but some argue that the comics, as we know them today, are an American creation. Clearly, the United States has played an outsize role in the development of this underappreciated art form.

12.13.1982: Arnold, a syndicated strip by Kevin McCormick noted for its off-beat sense of humor, debuts. It ran until 1988.
 

12.13.1987: George Wunder dies in New Milford, Connecticut, at 75. He drew Terry and the Pirates for more than two decades after creator Milton Caniff called it quits in 1946.

Most of the information listed here from one day to the next comes from two online sites -- Wikipedia, and Don Markstein's Toonopedia -- as well as 100 Years of American Newspaper Comics, edited by Maurice Horn. Note that my focus is on American newspaper comic strips (and the occasional foreign strip that gained popularity in the United States). Thus, comic books and exclusively online comics are not included here.
