Sir Evan Nepean, 1st Baronet, PC FRS (9 July 1752 – 2 October 1822)[1] was a British politician and colonial administrator.

[2] Nepean entered the Royal Navy on 28 December 1773, serving on HMS Boyne as a clerk to Capt.

During the American Revolutionary War he served as secretary to Admiral Molyneux Shuldham, in Boston in 1776 and again at Plymouth (1777–78).

In this position, he came to have responsibility for naval and political intelligence which led to him running a network of spies across Europe.

The Bridport Town Hall, designed by architect William Tyler RA, was given a clock tower with cupola, in about 1805, by Sir Evan.
