An offprint from Vol. II, No. 5, November 1925 of the Journal of the Optical Society of America and Review of Scientific Instruments. Wraps. Alice H. Armstrong was a Wellesley college graduate with a long career in physics. She was employed before graduate school at the National Bureau of Standards for about two years, and was in charge in certifying the radium sold in the United States. She and (truncated) other technicians would measure the incoming samples against standards (one created by Curie) to determine what the samples contained. Later she was accepted for graduate work at Radcliffe. Her oral history interview in the Niels Bohr archives is quite interesting and tells among other things about an accident with Curie's radium standard, women being unable to enter some classrooms at the time, and various people she worked with or saw during her career.
