John Seller

John Seller (1632–1697) was an English cartographer. He worked as compiler, publisher, and seller of maps, charts, and geographical books. From 1671 he was hydrographer to the King.

Early life Seller, son of Henry Seller, a cordwainer, was baptized in London on 29 December 1632. In 1654 he became a freeman of the Merchant Taylors' Company, and he became a brother of the Clockmakers' Company in 1667. He was a compass maker, and continued this occupation throughout his career.

His trial, and The English Pilot Seller's subsequent career was affected by being put on trial in 1662, accused of high treason: it is thought he repeated a rumour about a plot involving a cache of arms. Those involved were executed, and although Seller was found guilty and imprisoned, he was later pardoned. In this way his name and occupation became known: the episode may have been a factor in his eventual appointment in March 1671 as hydrographer to the King.

Later publications

The Coasting Pilot appeared in 1672, and Atlas maritimus in 1675. Atlas Anglicanus, a projected large-scale atlas of England and Wales, was not completed, although new surveys of six counties were published from 1675 to 1681, and a map of London by John Oliver, who was associated with the project. Atlas caelestis, the first British celestial atlas, appeared in 1680.

Seller wrote textbooks including Practical Navigation (1669), A Pocket Book containing several choice Collections in Arithmetic, Geometry, Surveying, Dialling, &c. (1677); and The Sea-Gunner, shewing the Practical Part of Gunnery as it is used at Sea (1691). He also produced nautical almanacs.

Family Seller was for many years settled in Wapping; he had also a shop in Exchange Alley, near the Royal Exchange. He and his wife Elizabeth had three daughters and two sons; John Seller, junior, had a shop in Cheapside, where his father's publications were on sale.

He died in May 1697, and was buried at St John's Church, Wapping.
