In December of 1675, in a desperate race with Christiaan Huygens over a patent for a spring-regulated watch, Robert Hooke, FRS (Fellow of the Royal Society of London) characterized the clock maker Thomas Tompion as a ‘Slug’, a ‘Clownish Churlish Dog’ and a ‘Rascall’, because Tompion was making a watch of Hooke's design too slowly for the latter's taste. It was Hooke's watch, not Tompion's; Hooke was the patron and Tompion the client. Fifty years later Tompion's apprentice, George Graham, made watches and clocks and quadrants for other Fellows of the Royal Society, yet these instruments were known as Graham's clocks and Graham's quadrants. Language such as Hooke had used towards Tompion was inconceivable towards Graham; he was a member of the Royal Society's governing body, the Council, and had published several significant papers in the Society's journal, the Philosophical Transactions, in which his testimony on and experiments in astronomy, magnetism, horology and metrology were unquestioned. Yet in the early decades of the eighteenth century one could still go to his shop in London's Strand and buy a watch or a clock from him. Like Tompion, George Graham, FRS was a shopkeeper. Nor was he alone in the eighteenth century, at that supposed bastion of gentlemen, the Royal Society. Nearly two-thirds of the membership had to work for a living in one way or another, some rather grandly as high government officials, senior army officers, clerics with ample livings and physicians and lawyers with large and successful London practices ; others more modestly as sailors, surgeons, apothecaries, schoolteachers, engineers, attorneys and instrument-makers. The latter group included some of the most scientifically eminent members of the Royal Society in the eighteenth century: the sailor James Cook (geography), the printer Benjamin Franklin (electricity), the teacher and preacher Joseph Priestley (chemistry), the instrument-maker and engineer James Watt (chemistry), the musician William Herschel (astronomy), and the silk weaver and optician John Dollond (optics). None of these men were gentlemen (though many of their sons or grandsons became so) yet they made science and were acknowledged to have done so; their papers were published and their best work awarded medals.
