The mission of the Association is promotion of the legacy of Maria Mitchell and exploration, education and enjoyment of nantucket's land, waters and skies beyond. In fulfilling the mission they recognize the historic persona of Maria Mitchell, the foremost american woman scientist and educator of the 19th century, and her potential impact on contemporary thought by passing on her legacy of intellectual curiosity, respect for and love of nature, learning by doing, and the ideal of individualism. The association's contributions to astronomy, science, and education are the basis for their continuing tradition of high quality research and teaching which inspires today's learners and tomorrow's scientists. The Association also provides scientific resources and educational programs for the community, uses Nantucket island as an exceptional natural laboratory in which to study science and the environment, and maintains research and/or representative collections of nantucket's biodiversity.

The names, titles, and compensation shown on this page are reproduced from IRS Form 990 filings, which are public records.

Philanthropy.org does not alter the content of those filings. All information appears exactly as reported by the filing organization for the tax year shown.

We publish only information contained in the public IRS filing — and less than the filing contains. Our profile pages do not display street addresses, telephone numbers, personal email addresses, or other personal contact information, even where the filing includes them.

Many people share the same name. A name shown on this page reflects only what one organization reported in one IRS filing for one tax year. It should not be interpreted as identifying any other individual with the same or a similar name.

If you are no longer affiliated with the organization, your name will generally stop appearing in future IRS filings once the organization no longer reports you. Pages for tax years in which you were reported remain published because those filings remain part of the public record.

Philanthropy.org does not alter or remove IRS filing records. Removing a page from this website would not remove the underlying IRS filing, which remains publicly available from the IRS and other publishers of the same information.

If you believe the IRS filing itself is inaccurate, corrections must be made by the filing organization or the IRS directly.
