Born in 1673 George Graham was one of the most eminent English makers. He was apprenticed to Thomas Tompion in 1688 and was free of the Clockmakers Company in 1695, becoming Master in 1722. After completing his apprenticeship he became Tompion's assistant in 1796 and partner circa 1711-1713, succeeding him after his death. He used verge movements up until 1726 and then mainly cylinder. Graham died in 1751 and is buried alongside Tompion in Westminster Abbey. Examples of his work can be found in most major collections.
