Thomas Bedwell (died April 1595) was an English mathematician and military engineer.
Bedwell matriculated as a sizar of Trinity College, Cambridge in November 1562.
[1] He was appointed to the office of keeper of the ordnance stores in the Tower.
In conjunction with Frederico Genebelli he was employed as a military engineer in strengthening the works at Tilbury and Gravesend at the time of the Spanish Armada.
The two are sometimes confounded, chiefly, it would appear, on account of an ambiguity on the title-page of the first of two works published by the nephew in explanation of a 'ruler' or mesolabium architectonicum which the uncle had devised to facilitate carpenters' calculations.
