Henri Labrouste

Pierre-François-Henri Labrouste () (11 May 1801 – 24 June 1875) was a French architect from the famous 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. Provided by Wikipedia
