Maria Mitchell deserves to be honored on the newest series of U.S. circulating commemorative quarter dollars, 2022-2025. She was the first American woman to be a professional astronomer, and one of the first American astronomers acknowledged by both European and American academic communities. An informally educated autodidact, she became the first professor of astronomy at Vassar. The spotlight of fame fell on her when she was the first person in history to discover a comet using a telescope. The year was 1847. She was 29 years old. For her work, she won the gold medal offered by the King of Denmark.
Her name is pronounced “ma-RYE-ah” (like the wind in Oklahoma). Born on August 1, 1818, she was raised on Nantucket where her father was a naturalist and banker. Her parents, William and Lydia (Coleman) Mitchell, were Quakers and her commitment to social equality was aligned to their faith. Largely self-taught, she attended classes at local schools, one of them run by her father. She studied mathematics (of course) and also learned astronomy, surveying, and navigation. One of her father’s occupations was setting the chronometers of whalers and other ships that harbored at Nantucket, and she did the work when he was away on the mainland, often at Harvard College.

Mitchell owned a Dollond-style achromatic ship’s telescope (3-inch aperture; 46-inch focal length). In 1847, the family lived in the Pacific Bank Building on Main Street in Nantucket because her father was the head cashier there. She observed from the roof. On October 1, she saw a faint star that was new to her; and she soon verified that it was not listed in the tables and charts. Tracking it, she determined that it was a comet publishing her calculations of its orbit in Silliman’s Journal of Yale (later known as the American Journal of Science). That helped to secure her claim to primacy of discovery and the winning of the gold medal.

(As with several others to astronomy leaderships, no replies have come.)
Later, she moved briefly to Boston and computed the orbit of Venus for the US Nautical Almanac . She served as the librarian of the Boston Athenaeum and then toured Europe on her own, meeting with John Herschel, George Biddle Airy, and other astronomers. She returned to the States, and in 1865 she was appointed professor of astronomy at Vassar College, which, ironically enough paid her less than other professors, though not for her lack a university degree. She took her students to observations of the transit of Venus and solar eclipses (1869, 1878, and others) in Nebraska and Colorado.
