Rupert Thomas Gould (16 November 1890 – 5 October 1948) was a lieutenant-commander in the British Royal Navy noted for his contributions to horology (the science and study of timekeeping devices).

[3] Afterwards he was stationed at the Hydrographer's Department at the Admiralty, where he became an expert on various aspects of naval history, cartography, and expeditions of the polar regions.

His last years were spent at Barford St Martin near Salisbury, where he used his horological skills to repair and restore the defunct clock in the church tower.

In spite of two more nervous breakdowns, he wrote and published an eclectic series of books on topics ranging from horology to the Loch Ness Monster.

In 2000, Longitude, a television dramatisation of Dava Sobel's book Longitude: The True Story of a Lone Genius Who Solved the Greatest Scientific Problem of His Time, recounted in part Gould's work in restoring the Harrison chronometers.

He interviewed many witnesses and collated evidence for the creature that resulted in the first major work on the phenomenon, entitled The Loch Ness Monster and Others.

After this, Gould became the de facto spokesman on the subject, being a regular contributor to radio shows and newspaper articles.
