GRAHAM, George, clock and watch-maker, the most ingenious and accurate artist of his time, was born in 1673. After his apprenticeship, Mr Tompion received him into his family on account of his merit, and treated him with a kind of parental affection as long as he lived. Besides his universally acknowledged skill in his profession, he was a complete mechanic and astronomer; the great mural arch in the observatory at Greenwich was made for Dr Halley, under his immediate inspection, and divided by his own hand; and from this incomparable original, the best foreign instruments of the kind were copied by English artists. The sector by which Dr Bradley first discovered two new motions in the fixed stars was of his invention and construction; and when the French academicians were sent to measure a degree of the meridian in Lapland, with the view of determining the figure of the earth, Mr Graham was considered the fittest person in Europe to supply them with instruments. He was for many years a member of the Royal Society, to which he communicated several ingenious and important discoveries. He died in 1751.
