The man who restored Harrison's clocks to proper working order shared an equal billing with him in the TV adaptation of Longitude, and indeed his own labours and dedication were comparable to the clockmaker's.  Rupert Gould was a navigation officer in the Royal Navy, and so would have had a particular interest in the story of Longitude.

As well as a definitive guide to maritime clocks, he wrote books on sea serpents, "unexplained facts" and the Loch Ness Monster.
