  Géerard Debreu was one of the leading economists
    in the development of mathematical economics from the
    1950s onwards.  His paper with Kenneth Arrow proving
    the existence of equilibria in economic models with
    producers and consumers was published in 1954.
    He was awarded the Nobel Memorial Prize in Economics

   - Stanford Engineering Hero Lecture: Kenneth Arrow (Stanford online, available on YouTube)
- This is a lecture for a general audience, essentially
    autobiographical, where Arrow describes how, with a background
    in mathematics and statistics, his career developed through
    wartime work in meteorology and the then new field of
    “operations research”.  He describes his
    developing awareness of the development of Linear Programming
    and the Simplex Method by George Dantzig and, in the
    Soviet Union, by Kantorovich, and of the growing importance
    of computing in solving problems arising in this field.
    He subsequently came to Stanford University with a joint
    appointment as a professor of Economics and Statistics.
    Arrow starts discussing General Equilibrium 50 minutes
    into the lecture.
