My world had been so shaken that I experienced something very like a nervous breakdown. He also writes in detail concerning some points—.

At one point she considered leaving Harvard because of her low status and poor salary. Payne, with Annie Cannon, eventually received the title of Astronomer from Harvard. The nomination process is initiated by the thesis advisor and the nominator must be a DAP member.

At most two letters seconding the nomination.

I should not have thought he was the same man, and I feel quite differently about him—certainly I shall not be afraid personally of him any more. She showed that the great variation in stellar absorption lines was due to differing amounts of ionization at different temperatures, not to different amounts of elements.

She attended St Paul's Girls' School.

It was the best of times because of a spirit of reaching out into new fields of human endeavour, in politics, in the arts, in science and engineering, and in the application of electricity and of the internal combustion engine.

Her thesis explained the composition of stars. She published her conclusions in her second book, Stars of High Luminosity She found that siliconcarbonand other common metals seen in the Sun's spectrum were present in about the same relative amounts as on Earth, in agreement with the accepted belief of the time, which held that the stars had approximately the same elemental composition as the Earth.

Though she was soon disillusioned by botany, her love of taxonomy found a natural niche in her ultimate pursuit of astronomy, where she eventually became a relentless classifier of variable stars. Otto Struve, ApJ 64Selection Committee members who have mentored or otherwise co-authored with any candidate will recuse themselves from selection of finalists or awardees as appropriate.

A brilliant student more interested in physics than natural sciences, she was advised by Professor Arthur Stanley Eddington to pursue graduate studies at Harvard College in the more liberal United States. After being introduced to Harlow Shapleythe Director of the Harvard College Observatorywho had just begun a graduate program in astronomy, she left England in On a tour through Europe inshe met Russian-born astrophysicist Sergei I.

In Cecilia Payne became the first person, woman or man, to receive an Ph. Although we know today that this high abundance is real, at the time it produced an apparent anomaly with respect to the assumed homogeneity of the solar system. Cambridge University Press, I am extremely anxious to come if it is possible and am prepared to undertake anything that would enable me to work at Harvard.

Professionally, the Gaposchkins collaborated assiduously and produced definitive studies of variable stars, including Magellanic Cloud cepheids, in extenso.

From Around the Web. Other interesting books include: In she won a scholarship to Newnham College in Cambridge University, where she studied botany, physics, and chemistry. Alcock and Brown first flew across the Atlantic Ocean in and air-mail services began.

Payne-Gaposchkin, Cecilia (1900-1980)

To show that so much of the apparent discrepancy in the position of the maximum intensity is traceable to the relative abundance of atoms in higher and lower excitation states, and to have the computed pressures come out as they do after this correction, is very nice indeed.

The story has resonance for those beginning careers today, in a very different academic environment. She quickly began an investigation of the stellar spectra being compiled for the Henry Draper catalog.

Because astronomy continued to be seen as a branch of mathematics she was unable to change her major field of study to astronomy from physics. Later she surveyed all the stars brighter than the tenth magnitude.

Cecilia continued to publish and wrote several other books, some of them coauthored by her husband. At one point she considered leaving Harvard because of her low status and poor salary. All were pioneers in branches of nuclear physics and Cambridge was frequently visited by many world figures in physics such as Niels Bohr.

Sir Arthur Eddington, after giving the matter some thought, decided that there was no insuperable difficulty in her making a career in astronomy and indeed he did a great deal to help her.
