The Jamestown Banking Company, one of the old and solid financial institutions of Mercer county, was organized July 21, 1874, with a capital stock of $50,000. Its original officers were as follows: Dr. William Gibson, president; James McMaster, vice president, and W. W. Davis, cashier. By the death of Dr. Gibson, Mr. McMaster succeeded to the presidency, and remained at the head of the bank’s affairs until his death in 1897. The deceased thus added another strong claim to the fatherhood of Jamestown, upon whose homestead the main portion of the town was laid out and in the furtherance of whose interests he had always been foremost. In the meantime William A. McMaster, the son, had entered the bank, of which he became cashier in 1885, and when his father died, twelve years later, he was the only legitimate successor to the presidency. Under the able guidance of both father and son, the Jamestown Banking Company has successfully weathered all financial crises, national and local, and has long since been classed as a most substantial and progressive institution.
