Who Was Maria Mitchell?
Maria Mitchell was a pioneering astronomer known for her significant contributions to the field of astronomy, which she pursued with fervor and dedication, supported by her father. In 1847, she gained prominence for her discovery of a new comet, later named “Miss Mitchell’s Comet,” which established her reputation within scientific circles. Subsequently, she became a professor of astronomy at Vassar College in New York, where she engaged her students in tracking and photographing sunspots.
Early Life
Born on August 1, 1818, in Nantucket, Massachusetts, Maria Mitchell was the daughter of Quaker parents William and Lydia Mitchell. She received her early education in Nantucket, where her father recognized her keen interest in the night sky and nurtured her passion for astronomy by teaching her how to use a telescope. From 1836 to 1856, Mitchell served as the first librarian at the Nantucket Atheneum library, all while continuing her astronomical observations, studying solar eclipses, and observing celestial bodies such as Jupiter and Saturn.
Discovering “Miss Mitchell’s Comet” and Becoming America’s First Female Astronomer
On October 1, 1847, while scanning the skies from the roof of her father’s business, the Pacific National Bank, Mitchell discovered what she believed to be a new comet. Her assertion proved correct, leading to the identification of the celestial object now formally designated as C/1847 T1, or “Miss Mitchell’s Comet.” In recognition of her groundbreaking discovery, she was awarded a gold medal by Frederick VI, the king of Denmark, who had a personal interest in astronomy. This honor marked her as the first professional female astronomer in the United States.
Mitchell’s discovery garnered her widespread respect among her peers in the scientific community. In 1848, she became the first woman to be elected to the American Academy of Arts and Sciences. The following year, she contributed her calculations to the American Ephemeris and Nautical Almanac, and in 1850, she was elected to the American Association for the Advancement of Science.
In 1856, Mitchell left her position at the Atheneum to embark on travels across the United States and abroad. In 1865, she joined the faculty at Vassar College, where she became a well-respected professor of astronomy. Alongside her students, Mitchell continuously tracked and photographed sunspots and documented the transit of Venus across the sun in 1882, a rare astronomical event occurring only eight times between 1608 and 2012.
In 1869, she was elected to the American Philosophical Society. Four years later, she co-founded the Association for the Advancement of Women, serving as its president for three years.
According to the National Women’s History Museum, Maria Mitchell once remarked, “We especially need imagination in science. It is not all mathematics, nor all logic, but it is somewhat beauty and poetry.” Her legacy endures as an inspiration to future generations in the pursuit of scientific knowledge and exploration.
Death and Legacy
In 1861, following the death of her mother, Maria Mitchell relocated to Lynn, Massachusetts, to live with her father. In declining health, she retired from her teaching position at Vassar College in 1888. Maria Mitchell passed away on June 28, 1889, and she is interred alongside family members at Prospect Hill Cemetery in Nantucket.
In recognition of her pioneering contributions as the first female astronomer, the observatory in Nantucket was named the Maria Mitchell Observatory. Her legacy is further honored by the establishment of the Maria Mitchell Association, a World War II vessel named the SS Maria Mitchell, and a lunar crater designated as “Mitchell’s Crater.”
In 1994, Mitchell was posthumously inducted into the National Women’s Hall of Fame, acknowledging her significant impact on the field of astronomy and her role as a trailblazer for women in science.
