One night in Cleveland, Jerome Siegel couldn't sleep.
  It was summer 1933. He'd finished typing out The Man of Bronze. Joe Shuster had sketched Doc Savage with big muscular arms and legs for the illustrations.
  As soon as Jerry finished his typescript he began another. Now if Doc Savage could fly! he thought. If my character comes from a distant planet advanced in human evolution, but one that experiences an horrific earthquake... and the character's father is a scientist and inventor who sends his baby son to earth in a spaceship for safety... but there is no room for my little kid's mother and father...
  It was past midnight. Jerome tried to sleep. He had work in the morning. Loading and unloading his dad's furniture trucks. But one, two, three o' clock - every hour he was back on the typewriter.
  Six o' clock that morning Jerry dashed round to his friend Joe's house. He threw a pebble at the water pipe outside the older Shuster brothers' bedroom. Joe Shuster leaned out the raised window.
  Jerry waved paper at him.
  ' Hey, Joe. Read this!'
