Lecture Description

Engraving on English Table Clocks:  Art on a canvas of brass

In this presentation, Sunny Dzik will provide a survey of the decorative line engraving found on the backplates of English table clocks over the course of the 18th century. Hand engraving was a well-established method of decoration and relies on a simple hand tool, called a burin.  A video demonstration of the technique will be provided in the lecture. Expert hand engraving demonstrates several technical features including shading techniques and depth of field. The patterns of hand engraving over the course of the 18th century directly mirror major changes in decorative tastes including baroque imagery, rococo styles, and neoclassicism.  These engraving designs help to date the period when clocks were produced and place them in the context of other decorative arts of the period.  By the close of the 18th century, talent in decorative engraving remained high, but tastes had changed and line engraving on backplates came to an end.  The lecture presents numerous images available to all at: www.englishtableclocks.org

The Greenwich Observatory Clock that Changed Time Throughout the World and its Forgotten Creator. In the middle of the 19th Century, George Airy, the Astronomer Royal, saw the need to have a method of transmitting Greenwich Mean Time to various places in the U.K.  To this end he acquired a regulator clock for the Royal Observatory at Greenwich which not only would be the basis of timekeeping there but would be capable of transmitting the time instantaneously to any part of the Country as well as other places in the world.  This timekeeper would be the primary source of Greenwich Mean Time for 70 years.  Arguably, it was this clock that through the distribution of GMT caused GMT to be the de facto basis for timekeeping throughout the world. The story of this remarkable clock and its maker will be the subject of the presentation.

The London Horological Engine Turners.

In 19th century London, the making of a watch required the work of many individuals, each practicing their own specialism. This presentation will discuss the engine turners of Clerkenwell and the links between their work and the watch case and dial making trades. Who were the engine turners, where did they come from and what machinery did they use? Where did they acquire their unique skills and, as the London horological trade declined, what happened to these workers and businesses?

About the Presenter: 

Seth Kennedy is a professional antiquarian horologist with over 20 years’ experience, based in London, England.  He repairs and restores antique pocket watches, both the movements and the cases.  Alongside this work he also makes complete pocket watch cases in silver or gold using mostly traditional methods.  These cases are each made individually to re-home antique movements in a period appropriate fashion.

The Convention has about 25 lectures and workshops and many will be of interest to scholars and collectors including a talk by Keith Scoby-Youngs at the Convention Banquet (registration required) on the conservation of the Westminster great clock, Big Ben.
