The first-ever biography of Peter Arno, the legendary cartoonist who created what we now know as the New Yorker cartoon. The New Yorker's founding editor, Harold Ross, may have been exaggerating when he referred to Peter Arno as 'the greatest artist in the world.' Many may be familiar with examples of Arno's art, but few know the story of his extraordinary life and career. Arno's outsized life and career weren't without considerable challenges. In fact, he declared no one could do any good creative work unless he was 'mad at something.' Arno had plenty of inspiration in that respect and it fueled a roller coaster career which finally receives its full due.
