Update 4/10/07 - Tribute to Johnny Hart from Rick Newcombe, President and Founder of Creators Syndicate:
Johnny Hart was a towering genius among cartoonists. He had a profound influence on my life. Johnny stands out as one of the kindest, most generous, patient and all-round decent people I have ever known. (More from Newcombe, and from other cartoonists)
Michelle Malkin provides an excellent survey of Johnny Hart's life via quotes and links. A man gifted with wit and brilliance, his work incorporated his deeply held Christian faith. "B.C." appeared in more than 1,300 newspapers worldwide. I would read his work every day with anticipation and admiration. We may be grateful to the Author who invented Johnny Hart.
