Mitchell is the namesake of the [[Maria Mitchell Association]], the [[Maria Mitchell Observatory]], and the [[Maria Mitchell Aquarium]].

==Early years (1818–1846)==
Maria Mitchell was born on August 1, 1818, on the island of [[Nantucket]], [[Massachusetts]], to Lydia Coleman Mitchell, a library worker, and William Mitchell, a schoolteacher and amateur astronomer.<ref name=":03">{{Cite book|title=Notable women in the physical sciences : a biographical dictionary

Additionally, Nantucket's importance as a [[whaling]] port meant that wives of sailors were left for months, sometimes years, to manage affairs at home while their husbands were at sea, thus fostering an atmosphere of relative independence and equality for the women of the island.<ref>{{cite book|title=Captain Ahab Had a Wife: New England Women and the Whale Fishery, 1720–1870|url=https://archive.org/details/captainahabhadwi00lisa|url-access=registration|date=2000|publisher=UNC Press|isbn=0807848700|page=[https://archive.org/details/captainahabhadwi00lisa/page/52 52]|author=Lisa Norling}}</ref>

After attending Elizabeth Gardner small school as a young child, Mitchell enrolled in the North Grammar school, where her father was the first principal. When Maria Mitchell was 11 years old, her father founded his own school on Howard Street. There, she was a student and also a teaching assistant to her father.<ref>''Among The Stars: The Life of Maria Mitchell''. Mill Hill Press, Nantucket, MA. 2007</ref> In 1831, at the age of 12, Mitchell aided her father in calculating the exact moment of a [[solar eclipse]].<ref>Gormley, Beatrice.

William Mitchell's school closed, and afterwards she attended [[Unitarianism|Unitarian]] minister [[Cyrus Peirce]]'s school for young ladies until she was about the age of 16.<ref name=":06" /> Later, she worked for Peirce as his teaching assistant before opening her own school in 1835. Mitchell developed experimental teaching methods, which she later employed during her professorship at Vassar College.<ref name=":06" /> She allowed nonwhite children to attend her school, though the local public school was still [[Segregated education|racially segregated]].<ref name="bergland">{{cite book|title=Maria Mitchell and the Sexing of Science: An Astronomer Among the American Romantics|date=2008|publisher=Beacon Press|isbn=978-0807021422|page=[https://archive.org/details/mariamitchellsex00berg_0/page/29 29]|author=Renée L. Bergland|url=https://archive.org/details/mariamitchellsex00berg_0/page/29}}</ref>

In 1836, Mitchell began working as the first librarian of the [[Nantucket Atheneum]], a position she held for 20 years.<ref name="bergland" /><ref>{{cite book|url=https://archive.org/details/biographicaldict02ogil|url-access=registration|title=The biographical dictionary of women in science: Vol. 2: L–Z|date=2000|publisher=Taylor & Francis|isbn=9780415920407|editor=Marilyn Bailey Ogilvie|editor2= Joy Dorothy Harvey|editor-link=Marilyn Bailey Ogilvie|editor2-link=Joy Harvey|page=[https://archive.org/details/biographicaldict02ogil/page/901 901]|quote=Professional experience: Nantucket Atheneum, librarian (1836–1856)}}</ref><ref name=":06" /> The institution's limited operating hours enabled Mitchell to assist her father with a series of astronomical observations and geographical calculations for the [[United States Coast and Geodetic survey|United States Coast Survey]] and to continue her own education.'''<ref name=":06" /><ref name=":153" />''' Mitchell and her father worked in a small observatory constructed on the roof of the Pacific Bank building with a four-inch equatorial telescope provided by the survey.'''<ref name=":06" /><ref name=":153" />''' In addition to looking for [[nebula]]e and [[double star]]s, the pair produced latitudes and longitudes by calculating the altitudes of stars and the culminations and occultations of the Moon, respectively.<ref name=":06" />

In 1843, Mitchell converted to Unitarianism, although she did not physically attend a Unitarian Church until more than twenty years later. Her departure from the Quaker faith did not cause a break with her family, with whom she appears to have remained close.<ref name=":04">{{Cite web|title=Sweeper in the Sky.|url=https://digital.library.upenn.edu/women/wright/sweeper/sweeper.html|access-date=March 23, 2021|website=digital.library.upenn.edu}}</ref> Historians have limited knowledge about this period in Mitchell's life because few of her personal documents remain from before 1846. Members of the Mitchell family believed she destroyed many of her personal documents in order to keep them private, having witnessed personal papers blown through the street by the Great Fire of 1846, and because fear of another fire persisted.<ref>{{cite book|url=https://archive.org/details/mariamitchellsex00berg_0/page/82|title=Maria Mitchell and the Sexing of Science: An Astronomer Among the American Romantics|author=Renée L.

==Discovery of "Miss Mitchell's Comet" (1847–1849)==
At 10:50 pm on the night of October 1, 1847, Mitchell discovered Comet 1847 VI (modern designation C/1847 T1) using a Dollond refracting telescope with three inches of [[aperture]] and forty-six-inch focal length.<ref name="FAMOUSAMERICANS2">[[Eva March Tappan|Tappan, Eva March]], [https://archive.org/details/bub_gb_9HMAAAAAYAAJ ''Heroes of Progress: Stories of Successful Americans''], Houghton Mifflin Company, 1921.

On October 6, 1848, Mitchell was awarded a gold medal prize for her discovery by King Christian VIII of Denmark.<ref name=":04"/> This award had been previously established by [[Frederick VI of Denmark|King Frederick VI of Denmark]]  to honor the "first discoverer" of each new telescopic comet, a comet too faint to be seen with the naked eye.<ref name=":06"/> A question of credit temporarily arose because [[Francesco de Vico]] had independently discovered the same comet two days after Mitchell but reported it to European authorities first. Mitchell was declared the first to discover the comet and she was awarded the prize.<ref name=":14">{{cite web|url=http://www.mariamitchell.org/about/awards/maria-mitchells-gold-medal|title=Maria Mitchell's Gold Medal – Maria Mitchell Association|website=www.mariamitchell.org}}</ref> The only previous women to discover a comet were the astronomers [[Caroline Herschel]] and [[Maria Margarethe Kirch]].

Mitchell's medal was inscribed with line 257 of Book I of Virgil's ''[[Georgics]]'': "''Non Frustra Signorum Obitus Speculamur et Ortus" (Not in vain do we watch the setting and the rising [of the stars]).''<ref name=":5">{{cite web|url=https://www.perseus.tufts.edu/hopper/text?doc=Perseus%3Atext%3A1999.02.0058%3Abook%3D1%3Acard%3D257|title=P.

Mitchell traveled to Europe in 1857. While abroad, Mitchell toured the observatories of contemporary European astronomers [[John Herschel|Sir John]] and Caroline Herschel and [[Mary Somerville]].<ref name=":06"/> She also spoke with a number of natural philosophers including [[Alexander von Humboldt]], [[William Whewell]], and [[Adam Sedgwick|Adam Sedgewick]] before continuing her travels with [[Nathaniel Hawthorne]] and his family.<ref name=":06" /> Mitchell never married, but remained close to her immediate family throughout her life, even living in [[Lynn, Massachusetts]] with her sister Kate and her family in 1888.<ref>{{cite book|title=Maria Mitchell: The Soul of an Astronomer|author=Beatrice Gormley|date=2004|publisher=Eerdmans Young Readers|isbn=0802852645|pages=116–118}}</ref>

Though Mitchell did not have a college education, she was appointed professor of astronomy at [[Vassar College]] by its founder, [[Matthew Vassar]], in 1865, and became the first female professor of astronomy.<ref name=":23" /><ref name="HOWE1900" /> Mitchell was the first person appointed to the faculty and was also named director of the [[Vassar College Observatory]], a position she held for more than two decades.<ref name=":0">{{cite web|url=http://www.nwhp.org/biographies/|title=Biographies|publisher=National Women's History Project|date=August 1, 2017}}</ref><ref name="FAMOUSAMERICANS" /> Mitchell also edited the astronomical column of ''[[Scientific American]]'' during her professorship.<ref name=":06" /> Thanks in part to Mitchell's guidance, [[Vassar College]] enrolled more students in mathematics and astronomy than [[Harvard University]] from 1865 to 1888.<ref name=":14" /> In 1869, Mitchell became one of the first women elected to the [[American Philosophical Society]], alongside [[Mary Somerville]] and [[Elizabeth Cabot Agassiz]]. She received honorary doctorates from [[Hanover College]],<ref>{{Cite web |title=Sweeper in the Sky. |url=https://digital.library.upenn.edu/women/wright/sweeper/sweeper.html |access-date=October 2, 2023 |website=digital.library.upenn.edu}}</ref> [[Columbia University]],<ref>{{Cite web |title=Columbia's "Fair Doctors" – News from Columbia's Rare Book & Manuscript Library |url=https://blogs.cul.columbia.edu/rbml/2023/03/14/columbias-fair-doctors/ |access-date=October 2, 2023 |website=blogs.cul.columbia.edu}}</ref> and [[Rutgers Female College]].<ref>{{Cite web |title=Addresses at the commencement of Rutgers Female College, New York City, on conferring the honorary degree of Doctor of Laws upon Thomas C.

Mitchell employed many unconventional teaching methods in her classes. She reported neither grades nor absences, advocated for small classes and individualized attention, and incorporated technology and mathematics into her lessons.<ref name="HOWE1900" /> Though her students' career options were limited by their gender, she emphasized the importance of their study of astronomy. "I cannot expect to make astronomers," she said to her students, "but I do expect that you will invigorate your minds by the effort at healthy modes of thinking. When we are chafed and fretted by small cares, a look at the stars will show us the littleness of our own interests."<ref name="AAAS">{{cite web|url=http://www.amacad.org/publications/BookofMembers/ChapterM.pdf|title=Book of Members, 1780–2010: Chapter M|publisher=American Academy of Arts and Sciences|access-date=July 29, 2014}}</ref>

Mitchell's research interests were varied. She photographed planets such as [[Jupiter]] and [[Saturn]], as well as their moons, and studied nebulae, double stars, and solar eclipses.<ref name="aps">{{cite web|url=http://www.aps.org/publications/apsnews/200610/history.cfm|title=Maria Mitchell Discovers a Comet|work=This Month in Physics History|publisher=American Physical Society|access-date=November 1, 2012}}</ref><ref name="HOWE1900" /> Mitchell also developed theories around her observations, such as the revolution of one star around another in double star formations and the influence of distance and chemical composition in [[star color]] variation.<ref name="aps" />
[[File:Maria Mitchell in the Vassar College Observatory, Vassar College, June 1878.jpg|thumb|300x300px|Maria Mitchell inside the [[Vassar College Observatory]], 1878]]
Mitchell often involved her students with her astronomical observations in both the field and the Vassar College Observatory.<ref name="aps" /> Though she began recording [[sunspot]]s by eye in 1868, she and her students began photographing them daily in 1873.<ref name="aps" /> These were the first regular photographs of the Sun, and they allowed her to explore the hypothesis that sunspots were cavities rather than clouds on the surface of the Sun. For the total [[solar eclipse of July 29, 1878]] Mitchell and five assistants traveled with a 4-inch telescope to [[Denver]] for observations.<ref name=":13" /> Her efforts contributed to the success of Vassar's science and astronomy graduates, as twenty-five of her students would go on to be featured in ''[[Who's Who in America]].''<ref name="HOWE1900" />

After teaching at Vassar for some time, Mitchell discovered that she was being paid less than many younger male professors. Mitchell and [[Alida Avery]], the only other woman on the faculty at that time, demanded a salary increase, which they received.<ref>{{cite encyclopedia|url=http://vcencyclopedia.vassar.edu/faculty/original-faculty/maria-mitchell/maria-mitchell-salary-dispute.html|title=Maria Mitchell Salary Dispute|encyclopedia=Vassar Encyclopedia|publisher=Vassar College|access-date=November 1, 2012}}</ref><ref name="Beaton">{{cite book|url=https://books.google.com/books?id=uwceDAAAQBAJ&pg=PA54|title=Colorado Women: A History|author=Gail M.

==Social activism==
In 1841, Mitchell attended the [[anti-slavery]] convention in Nantucket where [[Frederick Douglass]] made his first speech, and she also became involved in the anti-slavery movement by [[boycotting]] clothes made of Southern cotton.<ref name=":04" /> She later became involved in a number of social issues as a professor, particularly those pertaining to [[women's suffrage]] and education.<ref name=":6" /> She also befriended various suffragists including [[Elizabeth Cady Stanton]]. After returning from a trip to Europe in 1873, Mitchell joined the national women's movement and helped found the [[Association for the Advancement of Women|Association for the Advancement of Women (AAW)]], a group dedicated to educational reform and the promotion of women in higher education.<ref name=":06" /> Mitchell addressed the Association's First Women's Congress in a speech titled ''The Higher Education of Women'' in which she described the work of English women working for access to higher education at [[Girton College, Cambridge]].<ref name=":6" /><ref name=":06" />
