About Leonard Digges, Esq, of Woolton Court
Leonard Digges (c.1515–c.1559) was a well-known English mathematician and surveyor, credited with the invention of the theodolite, and a great popularizer of science through his writings in English on surveying, cartography, and military engineering. His birth date is variously suggested as c.1515 or c.1520 (but certainly by 1530) Much of his work was expanded on, annotated, and published by his son, Thomas Digges. His son followed in his footsteps and was a pivotal player in the popularization of Copernicus's book De revolutionibus orbium coelestium. Notes written by Thomas Digges in the publication of the book Pantometria in 1570 contain descriptions of how Leonard Digges made use of a "proportional Glass" to view distant objects and people. Some, such as astronomer and historian Colin Ronan, claim this describes a reflecting or refracting telescope built between 1540 and 1559, but its vague description and claimed performance makes it dubious.

Behind the church was the original manor, Wootton Court, and birth place to the renown mathematician and surveyor, Leonard Digges in 1520. In the 1930's and as recently as 2002, prominent scientists have speculated that the discovery of previously unpublished manuscripts from 1576 is proof that Digges should be accredited with the invention of the first reflecting and refracting telescopes between 1540 and his death in 1559. This would be almost 40 years before the Dutchman Hans Lipperhay claimed to have invented it in 1608.
