The Birth of the Maria Mitchell Observatory: Celebrating Over 100 Years of Discovery

Jascin N. Leonardo Finger • June 30, 2025

As we are now complete with the conservation of the historic Maria Mitchell Vestal Street Observatory (MMO), I thought it would be good to post a series of blogs concerning it history and activities, as well as some of the amazing people who have made it what it is over the last 100 plus years. Therefore, over the next few weeks, the focus will be on the MMO.  And it is now open for tours – Monday through Saturday 11-1PM.


Founded in 1902, the Nantucket Maria Mitchell Association (MMA) had its beginnings in the Mitchell House where Maria Mitchell was born. Over the first few years, the preservation of the Mitchell House, family artifacts, and the collection and display of Nantucket’s native flora and fauna, as well as a small library, were the key components of the MMA. Special “Moon Evenings” were held on the lawn and people observed Nantucket’s night skies using several small telescopes, including William and Maria Mitchell’s two-and-three-quarter-inch Dollond telescope.


The popular evenings led to the inevitable – a desire and need to expand based on the demands of the visitors to, and members of, the MMA. In 1906, Lydia Hinchman, a founder of the MMA and a family member, purchased the house and lot adjacent to the Mitchell House. The house – once the home of William Mitchell’s father and mother – was taken down.


The MMA began a dialogue with the Harvard College Observatory and its director, Edward Pickering, Ph.D. The connection to Harvard was to become essential to the success of the beginning years of the Maria Mitchell Observatory and continued a legacy of friendship and work – Maria Mitchell and her father worked with the Bonds who once ran the observatory at Harvard and the families were close friends.


Besides his assistance, Pickering asked a member of his staff, Annie Jump Cannon, to assist the MMA. This “provided an indispensable collaboration for Nantucket astronomy,” with Cannon spending two weeks on the island in 1906 and 1907 lecturing and teaching. While back at Harvard, she continued to teach the students on Nantucket by mail. Cannon would go on to be recognized as the leading woman astronomer of her generation and as the founder of the MMA’s Astronomy Department.

April 1878. The conference of Woman’s Congress officers met in Washington. Because we had one member in Washington we were invited to meet in that place. I went on at a great expense of time, money and strength . . . . We were in session at least nine hours. I think that more than half of that was used by Mrs. Spencer and Mrs. Sayles. The only motion which I carried through was to pay the Secretary $200 . . . In 1878, that was a long train(s) ride to Washington, DC from Poughkeepsie, NY and Vassar College. If Maria seems perturbed, I am sure she was. As president of the Association for the Advancement of Women, and thus the Congress, she had to be at the meeting. But it appears she did not get much say in the nine hour meeting. This was also a long trip to take when she had another, even longer trip coming up in July of 1878. In that month, she would travel with students and her sister, Phebe, out west to Colorado to view the eclipse and that train and wagon ride I am sure was weighing on her mind – not just the physical trip but making her way for an important eclipse viewing event.

Well, actually replace the roof! With funding from the Community Preservation Act and the work of Lydon and Sons, Inc. the Mitchell House is getting a new roof. The current one had come to the end of its useful life. A cedar roof can last a long time – longer than asphalt – and is more historically accurate. The roof we are removing was installed in about 1992 – replacing a roof from the 1930s that was not cedar but a combination of materials that actually yes, did last sixty years. The unfortunate issue has arisen that the roofwalk (walk) has to be replaced. This is NOT the original walk – nor that old of a walk. It’s likely from the 1970s or so and has been cobbled at over time. It’s not a functioning walk – no one is allowed on it – but the Mitchell House needs it none the less. Maria Mitchell and her father, William, likely used the walk for astronomical observations – in addition to the yard – but the walk is also protected as part of the preservation easement on the House. Walks – NOT and NEVER called widow’s walks – were used for preventing and putting out chimney fire and roof fires. In a place where wood was expensive and had to be brought from “the main” these were purely utilitarian. What good Quaker (or non-Quaker) would build a platform for his wife to stare out to the harbor to see if her husband was on his way home? The other issue is that the walk was completely resting on the ridge board – and actually was notched to accept the pitch and tip of the ridge board so they couldn’t work around it. I suspect this may have been the ways walks were once built – and also a crafty and smart thinking carpenter who came up with the idea. It makes the walk lower. But between that issue and the age of the walk and then the blizzard of February 2026 that packed gusts over 83 MPH (that’s Category 1 hurricane winds) the walk gave in. Balusters had been knocked out and the railings were loose and pulling away from the posts. So, we will also be working with Barber and Sons to create a new roofwalk – and they agreed to do this for us quickly which is also no small feat given how busy everyone is these days. So from the bottom of the Mitchell House’s heart (and mine) a big thank you to Chris Lydon and Lydon and Sons and crew, Barber and Sons / Beau and Nate Barber, the Community Preservation Committee, and Nantucket Preservation Trust (our easement holder)!
