The four-time Pulitzer Prize-winning cartoonist Herbert Block became a professional journalist at just 19, but even in high school he penned a weekly column for the school newspaper and created cartoons. Employed by the Chicago Daily News and the Washington Post, the editorial cartoonist explored the New Deal, the civil rights debate, Nazism and McCarthyism among his broad range of work. The Library of Congress is opening a tribute to Block Oct. 13, the birthday of the talented cartoonist, which will run through May 1, 2010. Block died in 2001 at age 91. (The Library of Congress)
