Robert Maskell Patterson, M. D., Sixth Director of the Mint
son of a former Director, was appointed by President Andrew Jackson, May 26, 1835. His term of office was marked by an entire revolution in the coinage, and the ready acceptance of those improvements which followed so rapidly upon the introduction of steam. Dr. Patterson possessed the advantage of foreign travel; and having become familiar with the discoveries which had been adopted in the French Mint, he inaugurated and perfected them, also introducing improvements, which are still in use, in the machinery of the Mint. His portrait is in the Cabinet.
