Jack Williams, photograph courtesy of the Chicago Historical Society, arrested in Chicago in 1904 "for having a bomb on his person." http://homdev.northwestern.edu/context/timeline/1904/42/

Upton Sinclair was in Chicago in 1904 to cover the stockyard strike for a Socialist weekly, "Appeal To Reason."  What he saw there, in the plight of the meatpackers, inspired his book THE JUNGLE.  I have uncovered nothing else about Jack Williams, pictured above, but he must have been one of the many union-organizers or anarchists in town in those days, threatening violence. 

I have always loved Chicago.  It's an exciting city in the Midwest, where you can still meet guys like Jack who could do you harm but manage to look kind of hot, even with a bomb on their person.  Or maybe because of it.
