She was an assistant at the Harvard College Observatory from 1897 until 1911, when she was appointed curator of astronomical photographs. She was responsible for the photographic discovery of 5 novas and about 300 variable stars. She is best known for compiling a bibliography of about 200,000 references to variable stars and for completing a catalog of more than 350,000 stellar spectra; the catalog is still accepted as an international standard. She was also the first woman to receive an honorary doctorate degree from the University of Oxford in 1925.

Contributions of Women to the United States Naval Observatory  Web site compiled by Merri Sue Carter provides information & brief bios of  obscure women astronomers who worked at the USNO before 1920. Although the observatory is one of the oldest scientific institutions in the United States, the contributions made by women staff members was confined to the last 100 years. According to Merri "This was in part due to the restrictions placed on women by society, as well as those on women in a military institution, and those imposed by the mission of the Observatory."  Not a single observation at the Naval Observatory was made by a woman until after World War I. Women were not allowed to observe because, "It would be immoral for women to be alone amongst the equipment at night."  And "Women did not have the abilities that would be required to observe nights."  An interesting web site providing insight into the early history of the USNO and 12 of the women astronomers.
Dr. Sandra Faber  Dr. Sandra Faber is a former student of Dr. Vera Rubin. She is a University Professor of Astronomy and Astrophysics Astronomer, at UC Observatories/Lick Observatory. Her research focuses on the formation and evolution of galaxies and the evolution of structure in the universe.
Dr. Anne Kinney  Dr. Anne Kinney is the Director of the NASA Origins program as well as her work on the Hubble telescope, Chandra X-ray telescope, Next Generation Space Telescope, Gravity Probe-B, and Planet Finder, to find and characterize Earth-like planets. Dr Kinney pursued her interest at the University of Wisconsin-Madison, where she received a degree in physics and astronomy. After several years study at the Niels Bohr Institute she attended New York University her Ph.D. in physics.
Williamina Paton Fleming  (1857-1911) Fleming discovered more than 300 variable stars, 10 novae, and 59 gaseous nebulae, and compiled lists of thousands of stars with peculiar spectra. The Harvard web site provides a brief biography and photos.
Cecilia Payne-Gaposchkin  (1900 - 1979)  Cecilia Payne was born May 10,1900 in Wendover, England. She  was educated at and received her bachelors degree from Newnham College in Cambridge, England in 1923 and her doctorate degree from Radcliff in 1925. She was the first woman to become a full professor at Harvard University in 1938. Her research at Harvard focused on stellar spectra led to her theory that Hydrogen and Helium were the most abundant elements in stars in spite of their differences in appearance. She was the first woman scientist to be awarded the Henry Norris Russell Lectureship from the American Astronomical Society in 1977 for her research.
Caroline Herschel  (1750-1848)  Caroline Herschel was the sister of Sir William Herschel. In 1783 she discovered three nebulae. On August 1, 1786, Caroline discovered her first comet, Comet Herschel (C/1786 P1), and became history's first women with this distinction. She discovered many other comets as well. The web site provides several links to related web sites for further reading.
Henrietta Swan Leavitt  (1868-1921)  During her career at the Harvard Observatory, Leavitt discovered more than 2,400 variable stars, about half of the known total in her day. Leavitt's is known for discovering "dwarf white stars". The web site provides several links to related web sites for further reading.
Maria Mitchell  (1818-1889)  Maria Mitchell was America's first professional woman astronomer and astronomy professor. Maria discovered Comet Mitchell (C/1847VI) on October 1, 1847. The Maria Mitchell Observatory used a 7.5-inch Alvan Clarke telescope. Today the Maria Mitchell Observatory continues to conduct astronomical research in Cosmology, variable stars, comets, active galaxies and other areas. The web site provides background information about Maria, links to the observatory, and information about the observatories programs, museum, and research.
Ellen Ochoa  Ellen Ochoa was the first Hispanic woman ever to be accepted into the NASA space shuttle program. Ellen was selected for the astronaut program in 1990, and flew in her first space mission (STS-56) in 1993. Other space shuttle missions: STS-66, STS-96, STS-110. Ellen She is a co-inventor on three patents for an optical inspection system, an optical object recognition method, and a method for noise removal in images. She graduated from Stanford University in 1981 and 1985, with a master of science degree and doctorate in electrical engineering. Currently she is the Deputy Director of Flight Crew Operations at the Johnson Space Center.
Dr. Sally Kristen Ride  Dr. Ride was the first American female astronaut in Space. Dr. Ride joined NASA in 1977. She was a mission specialist on the Challenger space shuttle. Dr. Ride retired from NASA in 1987. Dr. Ride was inducted into the Astronaut Hall of Fame at Kennedy Space Center on June 21, 2003.
Dorothea Klumpke Roberts (1861-1942)  Dorothea Klumpke Roberts was born on August 9, 1861 in San Francisco, CA. Educated in Europe she earned a Bachelor of Science degree from the University of Paris in 1886. Early in her career as an astronomer at the Paris Observatory she measured star positions, studied stellar spectrums, and meteorites.  Dorothea was elected as Director of the Bureau of Measurements at the Paris Observatory in 1891. She enjoyed a long and distinguished career during which she published two photographic atlases and associated catalogues of deep sky objects as a tribute to her husband Dr. Isaac Roberts. The Astronomical Society of the Pacific awards the Klumpke-Roberts Award in her honor. Minor Planets MP 339 Dorothea and MP 1040 Klumpkea were named in her honor.
Dr. Vera Rubin  Dr. Vera Rubin is a world renowned leader in the field of Astrophysics. In 1965 she became the first women permitted to observe at Palomar Observatory. Dr. Rubin is credited with proving the existence of “dark matter,” or nonluminous mass, thus forever altering our perceptions of the universe. Web site from UCLA Physics Dept. contains links to many of her articles and a bibliography of her research publications.
Dr. Carolyn Shoemaker  Dr. Carolyn Shoemaker has discovered more than 800 asteroids and 32 comets.
