The Berkshire Knitting Mills were once part of a triad of companies in Reading and Wyomissing, Pennsylvania, owned by Henry Janssen (1866-1948) and Ferdinand Thun (1866-1949), known as Wyomissing Industries, which also included the Textile Machine Works and the Narrow Fabric Company. Built and incorporated between 1892 and 1906, these companies expanded rapidly between 1900 and 1930, becoming the world’s largest manu­facturer of women’s hosiery. This item is a bound album of documentation and captioned photographs depicting the Berkshire Knitting Mills factory, workers, and manufacturing processes in the years 1906 to 1923, a period during which the mills were celebrated as the largest full-fashioned knitting mills in the world.
