Jul 17, 2020 · In 1976, mechanical engineer Bill Laycock wrote The Lost Science of John Longitude Harrison. The book outlined Harrison’s very different philosophy in pendulum clock design. Laycock’s work inspired horological sculptor Martin Burgess to create a pair of Harrison-type precision pendulum clocks.
John Harrison was born in Foulby, a village on the Nostell Priory estate near Wakefield. He followed his father into the carpentry trade and in his teens became interested in clock-making. But it was his life-long obsession with developing the marine chronometer to determine longitude and aid navigation of the seas for which he became well-known.
