Major Sir William Lloyd (29 December 1782 – 16 May 1857) was a Welsh military commander, and was one of the first Europeans to ascend a Himalayan peak.
In 1822 he began a journey through the Himalayas that took him as far as Buran Ghati on the Tibetan border, where he produced maps for the EIC, which continued to be used by the Indian military for many years.
[4] In November 1837, Captain William Lloyd played a role in the management of 'The Society for the Diffusion of Useful Knowledge' and was a distinguished member of one of the S. D. U. K's.
[2] In 1840, he published his journals as 'The Narrative of a Journey from Caunpoor to the Boorendo Pass in the Himalayan Mountains Via Gwalior, Agra, Delhi, and Sirhind by Major Sir William Lloyd and Captain Alexander Gerards's Account of an Attempt to Penetrate by Bekhur to Garoo and the Lake Manasarowara: For The Purpose of Determining the Line of Perpetual Snow on the Southern Face of the Himalaya (With Maps)', which was edited by his son, George Lloyd at Bryn Estyn.
Following the accidental death of his son in 1843 in Egypt, and the collapse of the family's bank during 1849, Major Sir William Lloyd retired from public life for a few years, spending his time at his villa at Llandudno, 'Plas Trevor'.
