The Antiquarian Horological Society (AHS) is a learned society formed in 1953. It exists to encourage the study of all matters relating to the art and history of time measurement, to foster and disseminate original research, and to encourage the preservation of examples of the horological and allied arts. The society's President is Dr Patricia Fara.
In order to achieve its aims, the AHS hosts meetings, talks and events around the UK and overseas; publishes a range of specialist books as well as a quarterly journal, Antiquarian Horology; and supports education, conservation and historical research through a series of bursaries, prizes and awards. It also runs special-interest groups on wristwatches, electric timekeeping and public clocks.
The AHS is run by a volunteer Council elected from the membership, from which a Chair, Vice-Chair and Librarian are nominated. The Council is supported by the AHS Secretary, Webmaster, and the Editor of Antiquarian Horology. Find out more about who we are below.
David Thompson and Alan Treherne, Vice-Presidents and distinguished former Council members, continue to support the society, as do numerous volunteers.
