Joshua Jebb

Sir Joshua Jebb, KCB (8 May 1793 – 26 June 1863) was a British officer of the Royal Engineers who participated in the Battle of Plattsburgh on Lake Champlain during the War of 1812, He became Surveyor-General of convict prisons. By 1850, Pentonville Prison which he had designed had become a template for prison construction across the British Empire. Michael Ignatieff described Pentonville as "the culmination of a history of efforts to devise a perfectly rational and reformative mode of imprisonment".

Jebb was also involved in designing Woking Convict Invalid Prison, Broadmoor Hospital, a secure mental hospital in Crowthorne in Berkshire, and Mountjoy Prison in the centre of Dublin.
