Bil Keane, creator of beloved and long-running comic strip The Family Circus, died after a long battle with congestive heart failure. He was 89.

Keane was known across America for his signature one-panel oval cartoons and reassuring, wide-eyed worldview through the lens of his main characters, based loosely on his children and home life. Family Circus, which began in 1960, still runs in over 1,500 newspapers today, even after Keane's son Jeff (the basis for character Jeffy) took over the comic as his father's health worsened.

Comic strip artists and political cartoonists have expressed their sadness at Keane's passing, influencing such disparate figures as Lynn Johnson of For Better or For Worse and Wiley Miller of Non Sequitur.

These cartoonists, in interviews with online blog Comic Riffs, reveal something few knew about a man whose strip was so focused on family values: he was whip-smart funny. Johnson, Miller, Jerry Scott of Zits and Hilary Price of Rhymes with Orange all remarked on their initial surprise at Keane's hilarious comebacks and general good-natured demeanor. For someone whose comics have been criticized for being sappy or simple, Keane could rattle off a one-liner with the best of them.

Bil was a misunderstood creative genius who knew how to write for his target audience, said Scott Adams of Dilbert fame. Critics were sometimes harsh, especially other cartoonists. But allow me to point out the obvious: If other cartoonists could make a family-oriented comic that was as popular as 'Family Circus,' they would have done it.
