Questions pondered by a Hagley catalog librarian are answered through her encounter with a choice sammelband from the Patrick M. Parkinson Collection of the History of American Banking.
This week's Hagley Vault post comes from our Lukens Steel Company photographs (Accession 1972.360) collection and shows the company's process for heat treatment of steel discs around the year 1950.
The Lukens Steel Company was a medium-sized, non-integrated steel company and one of the top three producers of steel plates in the nation. It was founded in Coatesville, Pennsylvania in 1810 and controlled by members of the Pennock, Lukens and Huston families in direct succession for over 180 years; the company is noted for being the first industrial company in the United States led by a woman, Rebecca Lukens (1794-1854).
