"Samuel Aldrich Crozer (1857-59, 61-68, first president of The Delaware County National Bank), son of John Price and Sallie L. (Knowles) Crozer, was born at West Branch, near Crozerville, Aston township, Delaware county, December 25, 1825. When only a few weeks over seventeen years, attending boarding school in Philadelphia, in February, 1843, news reached him that his father, John P. Crozer, had been thrown from a sleigh fracturing his thigh. Samuel A. Crozer was immediately summoned home, and mere boy as he was, into his care was given the direction of the office and financial affairs appertaining to his father's large manufacturing business. For many months John P. Crozer was unable to leave the house, and when he again resumed full management of his affairs he still retained his son in control of the departments which had been assigned to him during his father's illness, and in the conduct of which he displayed unusual ability. When, in 1845, John P. Crozer purchased the Chester mills and laid the foundations for the present Borough of Upland, to his son Samuel fell the duty of stocking and outfitting with machinery Mill No. 1, at that place, although at the time his son had not reached his majority. On January 1, 1847, Samuel A. Crozer was admitted to a partnership in the business, the firm becoming John P. Crozer & Son, which continued over nineteen years, until dissolved by the death of the senior member March 11, 1866...Mr. Crozer was an extensive traveler, having crossed the Atlantic eighty-odd times, and had visited all sections of the East, save China, Japan, and India, and the great islands of the Indian Ocean. In the Western Hemisphere, his journeys have been through all sections of the United States, Canada, Mexico, and the West Indies. Samuel A. Crozer died at Upland June 10, 1910, in his eighty-fifth year. " (Old Chester, PA: Biographical Sketches)
