Sharla Perrine Boehm earned a teaching degree from UCLA before channeling her talent for math into computer programming. While working at the Rand Corporation, she built a ground-breaking simulation, originally conceived to strengthen military communications during the Cold War. The simulation –and her work– would ultimately lay the foundation for the modern internet.

“The only time I ever saw something that I thought was abnormal…there was a human arm in the refrigerator,” said J. Peter Willard about his aunt, Mary Louisa Willard. Otherwise, he insisted, she was “very normal.” But Mary Louisa Willard, a chemistry professor at Pennsylvania State University in the late 1920s, left a strong impression on most people, to say the least. Her hometown of State College, Pennsylvania, knew her for stopping traffic in her pink Cadillac to chat with friends, and for throwing birthday bashes for her beloved cocker spaniels. Police around the world knew her for her side hustle: using chemistry to help solve crimes.

“La única vez que vi algo que me pareció anormal… había un brazo humano en el refrigerador”, dijo J. Peter Willard sobre su tía, Mary Louisa Willard. Por lo demás, insistió, era “muy normal.” Pero Mary Louisa Willard, profesora de química en la Universidad Estatal de Pensilvania a finales de la década de 1920, dejó una fuerte impresión en la mayoría de las personas. Su ciudad natal, State College (Pensilvania), la conocía por detener el tráfico en su Cadillac rosa para saludar a sus amistades, y por organizar fiestas de cumpleaños para sus queridos perritos cocker spaniels. La policía la conocía por su oficio secundario: usar la química para resolver crímenes.
