He was one of the first subjects here at FTT and I have been very fortunate to speak with his biographer Laura Petersen Balogh. Laura's Karl biography has just been released via McFarland. "Karl Dane: A Biography and Filmography" is quite wonderful and I highly recommend it. Yes its McFarland priced, BUT it is just so wonderfully written and researched. And trust me I don't hand out that judgment lightly.
