Lehigh’s Mountaintop Campus was originally home to Bethlehem Steel’s Homer Research Laboratory. The laboratory’s buildings atop South Mountain housed Bethlehem Steel researchers. Following the decline of the steel giant, Lehigh purchased five of the eight buildings and 742 acres of land from the company for $18.75 million. This purchase connected the Asa Packer and Goodman campuses and added an additional 370,000 square feet to campus.
