Who was the Chicago businessman behind those wonderful old CTA and South Shore Line posters, and of what crime was he acquitted?
The answer is Samuel Insull, a former secretary to Thomas Edison, who was one of the biggest men in Chicago before the stock market crash. He took the stand in his own defense and was acquitted on fraud and other charges, but never got his position back and died in Europe. Edward Bryant was the first reader with the correct answer, and if he can send me an e-mail with his address and preferred T-shirt size, I'll send him his shirt. Thanks to everyone who played.
