They had three children, Edward, katherine, and Peter. Her daughter remembers her as "an inspired seamstress, an inventive knitter, and a voracious reader." She and her family were members of the first Unitarian Church there, where she taught Sunday school. 21 She was also active with the quakers. 22 payne's younger brother, humfry payne (19021936 who married Dilys Powell, the author and film critic, became director of the British School of Archaeology at Athens. 23 Bibliography edit At the end of her life, she had her autobiography privately printed as The dyer's Hand. It was later reprinted in Cecilia payne-gaposchkin: An Autobiography and Other Recollections ( Cambridge University Press, 1984). Her academic books include: The Stars of High Luminosity (1930) Variable Stars (1938) Variable Stars and Galactic Structure (1954) Introduction to Astronomy (1956) The galactic novae (1957) reviews Significant papers include: — (1936 "On the Physical Condition of the supernovae proceedings of the national Academy.
Feynman's mother and grandmother had dissuaded her from pursuing science, since they believed women were not physically capable of understanding scientific concepts. But feynman was later inspired by payne-gaposchkin when she came across some of her work in an astronomy textbook. Seeing payne-gaposchkin's research published in this way convinced feynman that she could, in fact, follow her scientific passions. 17 Personal life edit While in school, payne created an experiment on the efficacy of prayer by creating two groups, one of which was a control group. Later on, she became an agnostic. 20 In 1931, payne became an American citizen. On a tour through Europe in 1933, she met Russian -born astrophysicist Sergei. She helped him get a visa to the United States and they married in March 1934, settling in the historic town of Lexington, massachusetts, a short commute from Harvard.

12 She also supervised Frank kameny, who became a prominent advocate of gay rights. 13 payne-gaposchkin retired from active teaching in 1966 and was subsequently appointed Emeritus Professor of Harvard. 14 She continued her research as a member of staff at the Smithsonian Astrophysical Observatory, and edited the journals and books published by wallpaper harvard Observatory for twenty years. 15 Influence on women scientists edit According. Kass-Simon and Patricia farnes, payne's career marked a turning point at Harvard College Observatory.
Under the direction of Harlow Shapley and. Sheridan (whom payne-gaposchkin described as a mentor 16 the observatory had already offered more opportunities in astronomy to women than did other institutions, and notable achievements had been made earlier in the century by williamina Fleming, antonia maury, annie jump Cannon, and Henrietta Swan leavitt. However, with payne-gaposchkin's. D., women entered the 'mainstream'. The trail she blazed into the largely male-dominated scientific community was an inspiration to many. For example, she became a role model for astrophysicist joan feynman.
This work later was extended to the magellanic Clouds, adding a further 2,000,000 observations of variable stars. These data were used to determine the paths of stellar evolution. She published her conclusions in her second book, stars of High Luminosity (1930). 7 Her observations and analysis, with her husband, sergei gaposchkin, of variable stars laid the basis for all subsequent work on them. 1 payne-gaposchkin remained scientifically active throughout her life, spending her entire academic career at Harvard. At first, she had no official position, merely serving as a technical assistant to Shapley from 1927 to 1938.
At one point she considered leaving Harvard because of her low status and poor salary. However, Shapley made efforts to improve her position, and in 1938 she was given the title of "Astronomer". She later asked to have this title changed to Phillips Astronomer. She was elected a fellow of the American Academy of Arts and Sciences in 1943. 11 None of the courses she taught at Harvard were recorded in the catalogue until 1945. 1 When Donald Menzel became director of the harvard College Observatory in 1954, he tried to improve her appointment, and in 1956 she became the first woman to be promoted to full professor from within the faculty at Harvard's Faculty of Arts and Sciences. 3 Later, with her appointment to the Chair of the department of Astronomy, she also became the first woman to head a department at Harvard. 14 Her students included Helen Sawyer Hogg, joseph Ashbrook, frank Drake, harlan Smith and paul. Hodge, who all made important contributions to astronomy.

7 Thus, her thesis established that hydrogen was the book overwhelming constituent of real the stars (see metallicity and accordingly was the most abundant element in the Universe. 8 When payne's dissertation was reviewed, astronomer Henry norris Russell dissuaded her from concluding that the composition of the sun was predominantly hydrogen and thus very different from that of the earth, as it contradicted the accepted wisdom at the time. She consequently described the result in her thesis as "spurious". 8 Russell realized she was correct four years later after having derived the same result by different means and publishing it in 1929. He acknowledged payne's work and discovery in his short paper but he is often credited for the conclusions they both reached. 9 10 Cecilia payne-gaposchkin at work After her doctorate, payne studied stars of high luminosity in order to understand the structure of the milky way. Later she surveyed all the stars brighter than the tenth magnitude. She then studied variable stars, making over 1,250,000 observations with her assistants.
3 Her thesis was "Stellar Atmospheres, a contribution to the Observational Study of High Temperature in the reversing layers of Stars". 6 Astronomers Otto Struve (d. 1963) and restaurant Velta zeberg called it "undoubtedly the most brilliant. Thesis ever written in astronomy". 1 payne was able to accurately relate the spectral classes of stars to their actual temperatures by applying the ionization theory developed by Indian physicist Meghnad Saha. 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 found that silicon, carbon, and 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. However, she found that helium and particularly hydrogen were vastly more abundant (for hydrogen, by a factor of about one million).
a degree because of her sex; Cambridge did not grant degrees to women until 1948. 5 payne realized that her only career option in the. Was to become a teacher, so she looked for grants that would enable her to move to the United States. After being introduced to harlow Shapley, the director of the harvard College Observatory, who had just begun a graduate program in astronomy, she left England in 1923. 3 This was made possible by a fellowship to encourage women to study at the observatory. The first student on the fellowship was Adelaide Ames (1922) and the second was payne. Doctorate edit Shapley persuaded payne to write a doctoral dissertation, and so in 1925 she became the first person to earn. In astronomy from Radcliffe college (now part of Harvard ).
Georg heinrich Pertz and the, swedenborgian writer, james John Garth Wilkinson. 2, cecilia payne's father died biography when she was four years old, forcing her mother to raise the family on her own. She attended, st paul's Girls' School. In 1919, she won a scholarship. Newnham College, cambridge University, where she read botany, physics, and chemistry. Here, she attended a lecture. Arthur Eddington on his 1919 expedition to the island of Principe in the gulf of guinea off the west coast of Africa to observe and photograph the stars near a solar eclipse as a test of Einstein 's general theory of relativity. This sparked her interest in astronomy.
