Robert Crumb, born August 30, 1943, is an American cartoonist and a seminal figure of the underground comix movement. Known for his bold, satirical, and often controversial style, Crumb created iconic works such as "Fritz the Cat," "Mr. Natural," and the "Zap!" series, which sharply critique 1960s American culture, sexuality, and politics. His art has profoundly influenced both the comic medium and popular culture, challenging mainstream norms while sparking debates over his portrayals of gender and race. Crumb’s legacy reshapes the aesthetic of American comics and provides a model of creative freedom for subsequent independent artists.
