In the early 20th century, the former Topeka enjoyed a remarkable run of political prominence, gracing the nation with Margaret Hill McCarter , the first woman to address a national political convention (1920, Republican); Charles Curtis , the only Native American ever to serve as vice president ('29 to '33, under Herbert Hoover); Carrie Nation , leader of the old temperance movement (and wielder of American history's most famous hatchet); and, most important, Alfred E. Neuman , arguably the most influential figure to an entire generation of Americans.
