The-Girls-of-Atomic-City

[Project medical section head Stafford] Warren - and the rest of the Manhattan Project - relied almost exclusively on Geiger counter tubes made by one woman at Chicago’s Met Lab, Nancy Farley Wood. Nancy had the touch. She had worked on designs of several radiation detectors and when she tried to train others to make the tubes, no one, Warren thought, was as good as Nancy. She later went on to start her own company, the N. Wood Counter Laboratory. The ‘N.’ was so that no one would know she, a woman, owned it.
