Input: Question: Where was the architectural historian for Time Team born? Passage:The team was supplemented by experts appropriate for the period and type of site. Guy de la Bédoyère has often been present for Roman digs, as well as those involving the Second World War such as D-Day and aircraft (such as the Spitfire). Architectural historian Jonathan Foyle has appeared in episodes relating to excavations of country estates. Paul Blinkhorn (pottery), Mark Corney (coins) and Jackie McKinley (bones) have appeared from time to time. Mick ‘the dig’ Worthington, an excavator in the early series, occasionally returned as a dendrochronologist, whereupon he was dubbed 'Mick the twig'. Margaret Cox often assisted with forensic archaeology, mainly between 1998 and 2005. Other specialists who appeared from time to time include historian Bettany Hughes, archaeologist Gustav Milne, East of England specialist Ben Robinson and David S. Neal, expert on Roman mosaics. Local historians also joined in when appropriate.
