14876 Dampier           Discovered 1990 Nov. 18 by E. W. Elst at the European Southern Observatory.
William Dampier (1651-1715) was the first Englishman to circumnavigate the world three times. The British Admiralty, very much impressed by his book A New Voyage Round the World, gave him the command of a Royal Navy ship which led to important discoveries in Western Australia.
