Thanks to Iolanthe Good, daughter of Annalisa Crannell and granddaughter of Carol Jo Crannell, all featured above!
My grandmother (Carol Jo Crannell, known to me as ‘Nana’) was a Phi Beta Kappa physics major at Miami University in the late 1950’s. She went from there to Stanford University, where she got a PhD in physics (she also got married and had a child, my mother, who went on to become a mathematician).
Nana moved to Maryland, where she took a job at Goddard Space Flight Center, NASA. She worked as a solar astrophysicist, building payloads that carried detectors that measured solar gamma rays. As part of her studies, she predicted the existence of an 15.11 MeV Gamma-ray line. See http://sprg.ssl.berkeley.edu/~tohban/wiki/index.php/The_15.11_MeV_Gamma-ray_Line_Detected%3F
Her payloads often flew on high altitude balloons; this photo shows me at age 2 with Nana next to the gondola carrying her detector. On the right, you can see the truck laying out and filling up the 1000-foot ballon that will carry the payload. Later in her career, her detectors flew on rockets — so yes, my grandmother WAS a rocket scientist!
P.S. I love the 3-generation picture you have of us in your header!
