In order to attend college, it was necessary for Paul to work during the summer and at other times whenever possible. One summer he secured a job at the steel mill in Steelton, Pennsylvania. His first day on the job was spent cracking limestone rocks with a heavy sledge hammer. By evening his hands were raw and bloody and his muscles ached so much that the pain kept him awake most of the night. Nevertheless, he was back on the job the next morning without complaint. Indeed, explaining to the foreman his need to earn money for college expenses, the foreman bandaged his hands and transferred him to easier work.
