John Harrison’s pioneering timekeepers are among the highlights of the Royal Observatory’s collection and there’s no better time to learn about them and the
man behind them than in the institution’s 350th year. John Harrison and the Quest for Longitude tells the story of the trials, tribulations and ultimate success of Harrison’s attempts to create a device that would enable seafarers around the world to measure time and longitude and would mark out Greenwich as a globally significant location for centuries to come.
