Richardus GlynneRICHARD GLYNNE

Richard Glynne (1681-1755), was apprenticed to Henry Wynne in 1696 in the Clockmakers' Company of which he became a freeman in 1705: he became Steward of the Company in 1725. He worked first at the sign of the Atlas and Hercules (1712-16) in Cheapside and subsequently (1718-29) opposite Salisbury Court in Fleet Street, London. On obtaining his freedom in 1705, he married Anne Lea, the daughter of the noted map and globe-sellers Philip and Anne Lea (see below). From at least 1712 he was working in association if not in formal partnership, with his mother-in-law, advertising a new pair of globes in 1712, and publishing and marketing maps. In parallel with this activity, he made and sold 'all sorts of Mathematical instruments, either for Land or Sea, according to the newest improvements' as he stated in an advertisement in 1726. There is another reference to advertising 'all Kinds of Dials, Spheres and Globes of all Sizes.' A variety of scientific instruments by Glynne are indeed known. All are of high quality, with clean, well executed engraving uncluttered by unnecessary decoration. Glynne's fine instruments recommended themselves to a fashionable clientele, and he was sufficiently successful to be able to retire at the relatively early age of 49 in 1729, his stock being auctioned at the shop of the optician Edward Scarlett in 1730. There is an impressive armillary orrery in the Science Museum in Oxford, dating from around 1720 and standing just over a metre in height. The Museum state on their website that it must have been at the top of his range: an impressive and expensive purchase by one of his most wealthy customers.


Richard Street was apprenticed to Thomas Tompion; he became a freeman of the Clockmakers Company in 1687 and was elected Junior Warden in 1713. He worked in Shoe Lane just off Fleet Street and there is evidence that he was responsible for some of Tompion's repeating watch movements. He was undoubtedly well connected and probably his most famous commission is the important Degree Clock which is now at the Old Observatory at Greenwich. This may have been "The black clock on the back stairs" described in Sir Isaac Newton's personal papers after his death. Sir Isaac had also commissioned from Street a fine and highly unusual clock as a gift for Doctor Bentley who was Master of Trinity College Cambridge in 1708, it apparently had an eccentric chapter ring and an expanding and contracting hand. There is no record of him after 1722 when it is presumed he died.. The dial of the wall clock sold by Sothebys and mentioned above has striking similarities to the dial of this clock by Richard Glynne.


Wynne, Henry (or Wynn) 1640-1709, fl.1654-1709: a London instrument maker who served his apprenticeship to Ralph Greatorex and later numbered Thomas Tuttell and Richard Glynne amongst his apprentices. He is noted for his magnificent double horizontal dials, such as the one at Drumlanrig Castle. He is also known for his ring dials, and the small book he produced explaining them as well as moon dials. In 1677 Wynne made the magnetic dip needles with which Henry Bond's longitude solution was tested. Wynne is also attributed with introducing the domestic barometer.


ScarlettIn 1718, Edward Scarlett (1688- † 1743), a London optician, put arms on eyeglasses, to hold them on the ears and with this, eyeglasses converted into spectacles. Single small lenses, with decorative stems, quizzing glasses and hand-held scissors glasses, were not only the talk of town, but also became the choice of many popular personalities, such as Goethe, Washington and Napoleon, during 1700-1800. Therefore, the credit of spectacles goes to Edward Scarlett, whereas the credit for the invention of bifocals goes to Benjamin Franklin. The interesting part of Franklin is that he was also a myopic. Once he got tired of interchanging two pairs of glasses constantly, hence he decided to get rid off this trouble. After much effort, he figured out the way to make his glasses let him see both near and far. He used to have two pairs of spectacles and cut the lenses of both half. Then, he put half of each lens in a single frame to invent a bifocal.

The mathematical playing cards by Thomas Tuttell are also a nice example of 18th century fascination with the sciences.
