Leonard Digges, born about 1515 and dead about 1559, was an English mathematician and surveyor, credited with the invention of the theodolite and a great populariser of science through his writings in English on surveying, cartography and military engineering. His birth date is variously suggested as about 1515 or 1520, but certainly by 1530. He was the only son of James Digges of Digges Court in Barham, Kent, and his second wife Philippe Engham. His son Thomas Digges expanded, annotated and published much of his work, including Pantometria in 1570, whose notes describe how Leonard used a proportional glass to view distant objects, which some scholars read as a telescope built between 1540 and 1559, though the vague description makes that doubtful.
