Two old men - Bert and Harry - were sitting quietly in a bar.
"When was the last time you made love to a woman?" Bert asked Harry.
"1945," replied Harry.
"My goodness!" exclaimed Bert. "That's a long time ago."
"Not really," said Harry, glancing at his watch. "It's only twenty past eight now."

George Graham

Died 20 Nov 1751 (born c. 1674).Eminent English watchmaker who was first a partner with, then successor to Tompion's business. Graham improved Tompion's cylinder escapement. In addition, he invented (c. 1715) the dead-beat escapement (in which the escape wheel remains stationary when not moving forward.) Using these two developments together, Graham's timepieces ran with an accuracy unsurpassed for more than a century and a half. He also made astronomical devices for Edmond Halley, James Bradley, the French Academy of Sciences, and Charles Boyle, 4th Earl of Orrery. For the latter, he designed a clockwork model showing the motions of the planets around the Sun, thereafter known as an orrery. He invented a beam caliper with a micrometer screw.
