life and work

Cecilia Helena Payne-Gaposchkin.

From 1919 she studied natural sciences , especially astronomy , at Cambridge University , which at that time did not award women any academic degrees . From 1923 she worked as part of a program to promote women at the Harvard University observatory as Harlow Shapley's first doctoral student . She worked with Annie Jump Cannon , who dealt with the evaluation of star spectra.

In 1925 she received her doctorate from Radcliffe College , because Harvard was too conservative for that. In her dissertation, she demonstrated that the variability of the stellar spectra does not reflect a correspondingly different composition, as was generally assumed at the time, but is primarily caused by thermal ionization . The composition of the stars is rather uniform and for most elements similar to the earthly.

Harvard Classification of Spectral Lines according to Annie Jump Cannon. The numerical subgroups are missing.

However, under pressure from Henry Norris Russell , Shapley's teacher, she had to revoke her finding that hydrogen and helium were the main components : “almost certainly not real” . After independent measurements, Russell confirmed this result in 1929. In retrospect, her doctoral thesis was described as “undoubtedly the most brilliant doctoral thesis” in the field of astronomy.

In 1956, she became Harvard University's first female professor of astronomy.

Personal

In 1931 Payne became an American citizen. On a trip through Europe in 1933, she met the Russian-born astrophysicist Sergei I. Gaposchkin in Germany. She helped him obtain a visa to the United States, and the two married in March 1934 and settled in Lexington, Massachusetts. Payne added her husband's name to her own, and the Payne Gaposhkins had three children: Edward, Katherine, and Peter. She died at her home in Cambridge, Massachusetts on December 7, 1979. Shortly before her death, Payne had her autobiography privately printed as The Dyer's Hand. It was later reprinted under the title "Cecilia Payne-Gaposchkin: An Autobiography and Other Memories".

Payne's younger brother Humfry Payne (1902-1936), who married the writer and film critic Dilys Powell, was the director of the British School of Archeology in Athens. Payne's granddaughter, Cecilia Gaposchkin, is Professor of Late Medieval Cultural History and French History at Dartmouth College.
