The Nantucket Maria Mitchell Association is a private non-profit organization located on the island of Nantucket, Massachusetts. The Maria Mitchell Association (MMA) was founded in 1902 to preserve the legacy of Nantucket native astronomer, naturalist, librarian, and, above all, educator, Maria Mitchell. After she discovered a comet in 1847, Mitchell’s international fame led to many achievements and awards, including an appointment as the first American Professor of Astronomy at Vassar College. Maria Mitchell believed in “learning by doing” and today that philosophy is reflected in MMA’s mission statement, programs, research projects, and other activities. The Maria Mitchell Association operates two observatories, a natural science museum, an aquarium, and preserves the historic birthplace of Maria Mitchell. A wide variety of science and history-related programming is offered throughout the year for people of all ages.
