Life

Memoir of a map of the county of Surrey (1793)

Grew up in a Village of the Mansions 1.5 miles east of Wakefield , with its healthy air and the York Academy operated by astronomer John Gargrave with Thomas Randall and his son John and Schoolmaster John Arden (1721-1792) from 1740-1754 for gentlemen , Joseph Linley went to London, where he completed an apprenticeship at Prescott's Bank, founded in 1766.

Prescott recognized his talent and placed him as assistant to Nevil Maskelyne , whereupon he worked from July 30, 1781 to September 29, 1786 as an astronomer at the Greenwich Observatory . During this time he also tested Thomas Mudge's timekeeper "Blue (1777) and Green (1779)" on behalf of the Board of Longitude , for which he later (around 1795) also tested "Wain's Horizon". For William Roy (1726–1790) he traveled to the observatory in Paris with chronometers to determine length and triangulation .

With Roy's partner William Crosley he then worked 1789-1790 on maps that were the forerunners of the Ordnance Survey Maps.

The painter John Russell made a pastel portrait of him.

He was also active throughout Britain. As a businessman in London , he worked with his wife Anna's brother, Friedrich Christian "Fred" Zimmermann, who in turn was married to Justus Ruperti's sister Caroline Ruperti. Ruperti later took care of the vocational training of the half-orphan William Lindley .

family

With his first wife, Anna Zimmermann († 1797 in childbed), he had two daughters who died early: Ann (1795–1805) and Elisabeth (1796–1807).
In 1800 Joseph married Catherine Searles (1772-1845), the daughter of the London architect and builder Michael Searles , for the second time . The couple had four children: Catherine (1802–84), Caroline (1804–1891), Joseph (1806–1885) and William (1808–1900). William and his son William Heerlein Lindley later became successful engineers.
