The first biography of Robert Crumb—one of the most profound and influential artists of the 20th century—whose iconic, radically frank and meticulously rendered cartoons and comics inspired generations of readers and cartoonists, from Art Spiegelman to Alison Bechdel. Robert Crumb is often credited with single-handedly transforming the comics medium into a place for adult expression, in the process pioneering the underground comic book industry, and transforming the vernacular language of 20th-century America into an instantly recognizable and popular aesthetic, as iconic as Walt Disney or Charles Schulz.
