Yesterday, Harvey Pekar was found dead in his home at the age of 70. For decades, while working as a freelance jazz critic and as a file clerk at a Veterans Administration hospital, Pekar published the irregular comic book series "American Splendor," an autobiographical series that featured his everyday experiences and often featured his commentary on politics and music. Though he wrote the series alone, many artists drew the stories within, resulting in acclaim for the anthology for its showcase of the many different artistic styles of the comic book medium.

Pekar rose in notoriety during the mid 1980s, due to theatrical adaptations of his comics and several personal appearances on "The Late Show with David Letterman." His graphic novels continued to get acclaim and he and his wife Joyce Brabner's book "Our Cancer Year" won a Harvey Award. In 2003, the general public became more aware of Pekar's life and cultural contributions when a film adaptation of American Splendor was released, receiving critical praise that resulted in multiple awards. Despite all of this, Pekar never left his job as a file clerk.

Harvey Pekar began his career in comics through his friendship with famous indie comic artist/creator Robert Crumb, the man behind various underground comics such as "Zap Comix," "Keep on Truckin'" and "Fritz the Cat." it was his respect for the medium of sequential art and his belief that most comic book creators were interested in "formulaic" stories as opposed to "adult stories" that prompted Pekar to begin "American Splendor". He couldn't understand why more people didn't take comic books seriously, saying on more than one occasion: "Comics are just words and pictures. You can do anything in the world with words and pictures."
