Isidore Justin Séverin Taylor was born in Brussels on 5 August 1789 and died in Paris on 6 September 1879. He was closely associated with the development of French theatre, a noted traveller and author, and a philanthropist. Originally destined for a military career, the young man neglected this in favour of travelling about Europe and later the Near East. Among the fruits of his travels was a series of books on the French regions, Voyages pittoresques et romantiques dans l’ancienne France (1820–63), the nearly 7000 lithographs in which were the first to catalogue the French artistic patrimony.
