Alfred de Glehn

Alfred George de Glehn (15 September 1848 – 8 June 1936) was a notable English-born French designer of steam locomotives and an engineer with the Société Alsacienne de Constructions Mécaniques (SACM). His steam engines of the 1890s combined elegance, high speed, and efficiency. De Glehn's express locomotives were first used on the Nord Railway and on the boat trains from Calais to Paris, where they impressed passengers with their speed.
