Bethlehem Steel I-beam rolling and Manhattan high-rises

[Tom holds up an I-beam section.] Here's shape — here's an I-beam. When I worked at Bethlehem Steel, this is what we did, we made bookends. This was back in the old days when Bethlehem Steel still existed and it was the second largest steel company in the world. We had a beautiful research laboratory on top of South Mountain in Bethlehem, Pennsylvania. Bethlehem had gotten its start by learning how to roll I-beams. It became second largest after US Steel — Andrew Carnegie's company — and the number two person at US Steel went and formed a company called Bethlehem Steel.
