Émile Mayrisch was born in Eich on November 10, 1862. He studied engineering and, after working at the steel mills in Rodange and Dudelange, he was appointed manager of the latter in 1897. Mayrisch was one of the driving forces behind the creation of ARBED in 1911 and became its first technical manager. His reputation was international. In 1922, he was elected to the Belgian-Luxembourg Economic Council. In 1926, he set up the first International Steel Agreement whose members were the national iron producers of France, Germany, Belgium, Saar, and Luxembourg. In 1927, Austria, Hungary, and Czechoslovakia joined this organization chaired by Mayrisch. Mayrisch died in a car accident in 1928.
