Archibald Johnston (May 30, 1864 – February 1, 1948) was a mechanical engineer who, favored by Bethlehem Iron Company management and senior Bethlehem Steel Company president Charles M. Schwab, became president of Bethlehem Steel Company. He was subsequently appointed as first vice president of the Bethlehem Steel Corporation in charge of foreign sales. While first vice president, he led a municipal consolidation campaign to create the modern city of Bethlehem, Pennsylvania, from the boroughs of Bethlehem and South Bethlehem. As the first mayor of the newly incorporated city, he presided over the construction of the Hill to Hill Bridge as chairman of the Bethlehem Bridge Commission, significantly enlarged the city's area, extended paved streets, water mains, and municipal sewerage, and provided the city's first municipal park. After leaving office, he returned to Bethlehem Steel and moved his family to nearby Bethlehem Township to a new property, "Camel's Hump Farm", formed from over 390 acres of land purchased beginning in 1919 from local farmers. Upon his retirement from Bethlehem Steel in 1927, he began describing himself as a "gentleman farmer" and continued in public service until his death at his home in 1948.
