Francis Birch (1903-1992) was an American geophysicist. In 1942, Birch worked at the MIT Radiation Lab, which was tasked with radar development.
Herbert M. Parker (1910-1984) was a British-American medical physicist. He worked at Chicago, Oak Ridge, and Hanford during the Manhattan Project, and is perhaps best known for inventing the rep (a precursor of the rad) and helping develop the rem to measure radiation dosage.
