    United States:United States:J. Willard Gibbs 1st PhD in Engineering in the U.S. (1863) L. M. Norton, MIT first ChE course (1888)1 t BS i Ch i l E i i U P l i (1892)1st BS program in Chemical Engineering, U Pennsylvania (1892)

    American Institute of Chemical Engineers (AIChE) formed 1908

    The chemical industry had a central position in the changing industrial y p g gworld of the late 19th century. This industry did not hatch fully grown; it

    was based on nearly a centurys worth of scientific advances in the universities particularly German universities.
