Eugène André Oudiné (1 January 1810, Paris – 12 April 1887, Paris) was a French sculptor and engraver of medals and coins, and devoted himself from the beginning to the medallist's branch of sculpture, although he also excelled in monumental sculpture and portrait busts. 

Pierre-François-Henri Labrouste (11 May 1801 – 24 June 1875) was a French architect from the famous École des Beaux-Arts school of architecture. After a six-year stay in Rome, Labrouste established an architectural training workshop, which soon became known for rationalism. He became noted for his use of iron-frame construction and was one of the first to realize the importance of its use.
