Jules-Constance Peyre was born in Swedan, and having trained under the famous animalier sculptire Bayre he joined the Sevre porcelain factory as a modeller (1845-1848) and went on to become Chief Designer (1856-1871). During some kind of sabbatical in the early 1850s he took obe of the factory’s most distinctive material formulations, bisque porcelain, and developed it into a much more durable and versatile synthetic marble and bronze.
