In the early 1900s, Duncan Sloan, a banker, overheard a casual conversation on a railroad passenger car that the Klotz Throwing Company was seeking a suitable site for a factory in western Maryland. Specifically, Klotz was looking to build a silk throwing mill that would wound raw silk into thread where it would then be shipped to silk manufacturers and woven into various textiles. The raw silk would be imported from Italy and other countries, washed, dried, and spun before being wound, or doubled, into skeins of thread.
