Joe Magarac is a folk hero of the Pittsburgh area steel mills. Historians debate whether he was an authentic folk legend or manufactured by newspapermen to give the Pittsburgh steel industry a much needed folk hero. Many believe the legend originated 100 years ago among Hungarian immigrant steel workers. In any case, by the 1930s, the stories of Joe Magarac were well established. He was a huge steel man who would appear out of nowhere to right a falling 50-ton crucible that threatened the lives of the steelworkers.
