We continue with the second part of the series Top Secret Rosies. This time it is dedicated to the twin sisters Doris Blumberg Polsky and Shirley Blumberg Melvin, considering that there are more than 80 mathematician women employed at the time to perform ballistic calculations for the army and programming of computers in the Philadelphia Computer Section. It was located at the Moore Electrical Engineering School of the University of Pennsylvania.
Certainly these women were quickly forgotten in spite of the fact that World War II was the best documented war to date. Considering the important role they played in winning it, these women only had to settle for the economic compensation they received. Their salary that was considered very high at the time, about $2000 per year (which may be ridiculous at the moment). Unquestionably they deserved more than this, a wider social recognition at least.
