Notes:

C Robert Moulton worked at the University of Chicago Metallurgical Laboratory during World War II, part of the Manhattan Project.  It was known informally as The Met Lab.

The work of these groups, which were part of a unit which became known as "Chemistry Section C-I", a part of a broader Chemistry Division, was concerned with the development of chemical procedures for the extraction of plutonium, for the purification of plutonium, and, in the later phases, for research on the isotopes of other heavy elements including other transuranium elements.

C Robert Moulton was Director of Personnel at the Met Lab. After 1946 he was assistant director of the Chicago Patent Group of the Argonne National Laboratory.

Key Details

    Role & Transition: Beginning in 1946, Dr. Moulton took on the role of Assistant Director of the Patent Division at Argonne National Laboratory—the direct civilian and research successor created out of the Met Lab at the end of the Manhattan Project.

    Responsibilities: In the post-WWII transition, the Argonne Patent Division was tasked with untangling, cataloging, and managing the vast portfolio of classified "vault case" patents and secret intellectual property that had been produced by Chicago Met Lab scientists during the war.

    Background: Prior to his patent administration work for the nuclear program, Dr. Moulton was a chemist and university professor (holding a Ph.D. from the University of Missouri) who later lectured at the University of Chicago and worked with the Institute of American Meat Packers.

    Tenure: He held the assistant directorship of the Patent Division from 1946 until his death in December 1949.
