Today in the history of the American comic strip: October 9

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.

10.9.1922: Created by Larry Whittington, Fritzi Ritz begins its run, with Ernie Bushmiller taking the helm in 1925. 
 

10.9.1943: Mike Peters, the creator of Mother Goose and Grimm, is born in St. Louis, Missouri.

10.9.1954: Michael Catron, co-founder (with Gary Groth) of Fantagraphics Books, is born. Created in 1976, Fantagraphics publishes anthologies of classic comic strips, among other works.

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.
