Barbara Bell (April 1, 1922 – September 25, 2017) was an American astronomer, affiliated with Harvard College Observatory, now the Center for Astrophysics | Harvard & Smithsonian, for her entire career. In addition to her work in astronomy, she contributed to the field of climate history, with studies of ancient Egypt.

Early life and education[edit]

Bell was born in Evanston, Illinois, the daughter of George Irving Bell and Hazel Seerley Bell.[1] She graduated from Radcliffe College in 1944, then earned a PhD from Harvard University in 1951.[2][3] Her dissertation, "A study of Doppler and damping effects in the solar atmosphere", was supervised by Donald Menzel,[4] and won the Caroline Wilby Prize in 1951.[5] Her younger brother George Irving Bell Jr. was a biophysicist at Los Alamos National Laboratory.[6]

Bell was said to have a sharp and curious mind, with a kind heart and cheerful disposition, especially towards her niece, Carolyn S. Bell.[7]

Career[edit]

Bell was an astronomer affiliated with Harvard College Observatory and the Center for Astrophysics | Harvard & Smithsonian for over fifty years between 1948 to the 1990s[8] working mainly on sunspots,[9][10] geomagnetic storms,[11] and other solar phenomena.[12][13] She served on various committees of the International Astronomical Union.[14]

Bell also researched and wrote on the climate history of ancient Egypt;[15][16] she is credited with being the first to explore climate change as a cause of famine and civil breakdown known as "The First Dark Age in Egypt", using records of the Nile's annual flood levels.[17][18] This research has been used extensively in archeological literature.[11]
