One of the foremost makers of scientific instruments in the first half of the 18th century.
He worked as a clockmaker with Thomas Tompion between 1695 and 1713. He took over from Tompion, based initially in Tompion's workshop at the corner of Water Lane in Fleet Street. In 1720 he moved to another workshop in the same road, remaining there until he died, when the workshop was taken over by Thomas Mudge. Graham invented the dead-beat escapement in 1715, the cylinder escapement perfected in 1725, and the mercury pendulum in 1726. He wasburied in Westminster Abbey, alongside Thomas Tompion.
