From Wikipedia, the free encyclopedia
Carol Jo Crannell (November 15, 1938 – May 10, 2009) was a solar physicist known for her work on solar flares and on the astrophysical observation of x-rays and gamma rays. She worked for thirty years at the NASA Goddard Space Flight Center.[1][2]
Crannell was born in Columbus, Ohio. She graduated from Miami University in 1960, and completed her Ph.D. in physics at Stanford University in 1967, with Robert Hofstadter as her doctoral advisor.[2] She worked at the Goddard Space Flight Center from 1974 until 2004, when she retired.[1][2]
Crannell also held an adjunct faculty position at Catholic University of America,[1] where her husband, Hall L. Crannell, is an emeritus professor.[3] Her daughter, Annalisa Crannell, is a mathematician at Franklin & Marshall College.[4]
Research
Crannell's doctoral research concerned particle showers. At Goddard, Crannell pushed for x-ray and gamma-ray observations of the sun, and led balloon-mounted experiments to make these observations.[2]
