This book is an exposition of the lesser-known work of the maverick clockmaker, John Harrison (1693-1776). McEvoy and Betts explore Harrison's background, methodology, and thinking. For those with a practical interest, the book is an excellent starting point for anyone wishing to make a pendulum clock.

Rory McEvoy has worked in horology for over twenty years. Following a postgrad diploma at West Dean College, Chichester, he practiced in conservation of antique clocks and watches before joining a London auctioneer as a specialist. Since 2010, he has worked at the Royal Observatory as Curator of Horology. Research interests include: timekeeping and astronomy, the development of the precision pendulum clock with particular focus on the work of George Graham FRS and the historical practice of measuring time in the laboratory. Jonathan Betts MBE, FSA, FBHI, FIIC, FRSA was appointed Senior Horology Conservator at the NMM in 1979, and Senior Curator of Horology in 2000. He is Vice Chairman of the Antiquarian Horological Society, is a Past Master of the Worshipful Company of Clockmakers (2014) and a Trustee of the Institute of Conservation. In 1989 he received the NMM Callender Award, in 2002 the Clockmakers' Company's Harrison Gold Medal, in 2008 the BHI Barrett Silver Medal and in 2013 the Plowden Medal (RWHA) for his contribution to Horology Conservation.
