Back in the Summer of 1939, “The Mighty Atom” Joseph Greenstein attempted an amazing (and quite dangerous) feat. He would be chained to a chair with a car traveling at 40 miles per hour spaced out far enough to give him two minutes of lead time. If the Atom couldn’t break free of the chains in time the speeding automobile would run right over him! A news magazine was on hand with a photo crew to document the action, and, as you can see, the Atom made it …barely.
