John Davis is proud to have been presented with the North American Sundial Society’s Sawyer Dialing Prize for 2009. The citation was:

In recognition of the superb quality of the dials he has created, and in appreciation of his historical research to enhance our knowledge of the dialists who preceded us and the craft they left us.

sawyer dialing prize 2009The trophy, a specialised glass windowsill dial, was made by Jim Tallman of www.artisanindustrials.com.

I am also pleased to have manufactured the dial with which Heiner Thiessen won the heiner-thiessen-globe-dialAmateur Prize in the 2005 British Sundial Society Sundial Design Competition.

I have published numerous articles on sundials (sometimes in collaboration with other authors), presented papers at conferences and given talks to various groups and societies. A list of articles from the British Sundial Society Bulletin, the North American Society Compendium and the Scientific Instrument Society Bulletin is shown here and some are available for download below (Adobe Reader pdf format).
