In 1908, Bethlehem Steel began making the beam, which revolutionized building construction and contributed to the age of the skyscraper. Its success helped make Bethlehem Steel the second-largest steel company in the world. Bethlehem, Pennsylvania was incorporated, virtually as a company town, by uniting four previous villages. In 1910, Schwab broke the Bethlehem Steel strike by calling out the newly formed Pennsylvania State Police. Schwab successfully kept labor unions out of Bethlehem Steel throughout his tenure (although Bethlehem Steel unionized in 1941, two years after his death).
