Clement Lempriere wasx the eldest son of Thomas Lempriere and Joan Beach, of St Helier, he was baptised in the Town Church on 18 January 1683.
He was a captain, though whether of a ship or in the army, is unknown. What is known from sketches which survive is that he was well travelled, although it is not known at what stage of his life or in what order he visited Scotland, Portugal, the Balearics and Bermuda.
Professionally he was a cartographer. In 1725 he drew up a map of roads in the Scottish Highlands and he was Draughtsman to the Civil Branch of the Ordnance Office with a salary of £100 a year and an office in the Tower of London until his death. He seems to have mixed his professional life with his art, publishing a map of Bermuda, engravings of his paintings of warships, and A General and Particular Prospectus of the Islands of Jersey, Guernsey, Alderney, Serc, Arm and Jethou.
A number of further maps were published after his death, including A new and accurate map of Jersey in 1755.
From A Biographical Dictionary of Jersey by George Balleine
Clement Lempriere (1683-1746), a cartographer and artist was the eldest son of Thomas Lempriere of St Helier and Jeanne Beach.
Early years Born 1683 , of his early life we know nothing, except that he was a captain, though in what service is uncertain. The usually accurate Thieme says, "by profession a ship's captain" but his obituary notice in the Gentleman's Magazine calls him "captain of a marching regiment".
He evidently travelled, for his sketches include views of Scotland, Portugal, Minorca, and Bermuda, but we cannot date his movements by them, for many of them were not published until after his death. His earliest publication seems to have been a map of The Roads between Innersnait, Ruthvan, and Fort William in the Highlands 1725. Two years later he was appointed Draughtsman to the Civil Branch of the Ordnance Office at a salary of £100 a year with an office in the Tower, a position which he held till his death.
He died on 9 July 1746.
