Joseph Bancroft & Sons Company.

Joseph Bancroft began manufacturing cotton cloth at a small mill in Rockford, Delaware, just north of Wilmington, on March 25, 1831. The mill was built in order to take advantage of the Brandywine River's water power and Bancroft adopted the traditional British spinning and weaving technology for use in his operation. The firm expanded steadily during the 1830s and 1840s as it began to produce cotton for both the Philadelphia and New York markets. In the late 1840s, Joseph Bancroft brought his two sons, William and Samuel, into the business assuring that the company would remain a family enterprise. During the Civil War, when the American market was largely closed to English imports, the Bancroft firm, like most other U.S. textile companies, prospered. After the war, the company developed a new bleaching process and began to concentrate on finishing cotton cloth. The firm was incorporated as the Joseph Bancroft & Sons Company on October 1,1889.

The company purchased the Kentmere Mills adjoining their property on the east in 1895 and concentrated manufacturing there, while the old Rockford property was devoted to bleaching, dyeing and finishing. In 1910, the Bancrofts purchased a third plant at Reading, Pa., and incorporated the Joseph Bancroft & Sons Company of Pennsylvania on May 28, 1911. Subsequently, all manufacture was concentrated at Reading, with the Wilmington facilities devoted to bleaching, dyeing and finishing. In the spring of 1925, the Bancrofts purchased a controlling interest in the Eddystone Manufacturing Company, another cotton manufacturer, and secured 100% control in 1929. The Eddystone Plant was converted entirely to the printing of cottons and linens, and a rayon finishing plant was installed there in 1930.
