Maria Mitchell Vestal Street Observatory Seminar Room Updates

Jascin N. Leonardo Finger • January 8, 2024

In 1987, the MMA added what was referred to as the Seminar Room Addition. It attaches to the Maria Mitchell Vestal Street Observatory (MMO) on the west side of the MMO and abuts what we have referred to as the Astronomer’s Cottage since we acquired the ca. 1830 structure in about 1922. Since 1987, the Seminar Room – so named as it provides lecture and work spaces for our astronomy interns and astronomy staff and others – has seen really no updates or changes. That is about thirty-six years – and it’s in need. We did add new work areas but it was minor changes. Now, with a gift from a descendant of Maria Mitchell’s younger brother, William Forester Mitchell, we are embarking on some updates to bring the Seminar Room into the 21st century – as we work to conserve the historic MMO.


On January 2, 2024, we began the demolition work (I hate the word demolition but this is a 1987 building so I feel a bit more comfortable.) We will be making some much needed office spaces, expanding the meeting and study space for the astronomy interns, making climate updates, improving the lighting and flooring, and making a small astronomy library space. Reminder that this is just to the 1987 space and only its interior – the historic observatory is having its own conservation focused work completed and we hope to begin to work on the interior of that portion next fall now that the exterior work was all completed this past spring. But what you are seeing in this image is the backside of the plaster and lath that makes the backside of the wall of the Astronomer’s Cottage – and the sill and other supporting timbers – pretty fun to see. It was first exposed when they added the Seminar Room addition in 1987 and removed the shingles and sheathing at that time – not something that was done this time and I wish they could have saved the sheathing boards and put the insulation between sheathing and the lathe!


Stay tuned!

In April and early May, at long last, the Mitchell House roof was replaced. (I noted this in an earlier blog.) I had also noted that the roofwalk, given the condition it was in and its location – sitting on the ridge – had to be replaced. They had thought they could jack it up – as they have done with other walks – but the Blizzard of February 2026 that was ALL wind (83 MPH winds – read Category 1 Hurricane) and no real snow, made the walk impossible to treat in such a manner (read: crumble). So, after much discussion, review by our preservation easement holder, and permits, as well as some fundraising, we are replacing the roofwalk. The prior walk was not the original. The original blew off in a gale in the late nineteenth century, replaced at some point in the 1930s, and likely replaced again in the 1960s or 1970s. Then, since that time, it was heavily repaired. Its framing members were notched to accept the ridge boards (read: peak) of the roof and I think that may have been an original way to construct a walk. Makes perfect sense – and gives the walk more support and a lower profile. It was after all about putting out chimney fires and preventing roof fires. People copied what worked – and there have been a few others noted to be built in this manner still. It presents an issue though – because if you need to work on the ridge board or close to it – you cannot get to it easily – I guess you may be able to access it to some extent by lifting the deck boards of the walk. The new Mitchell House roofwalk will sit about six inches above the ridge – which will also allow air to circulate better over the ridge and the shakes in that area. That is the only thing that will really be different. It is protected by a preservation easement – as part of the Mitchell House’s easement – and frankly, even if we did not have an easement, we would not want it to look any different. So keep your eyes to the skies at 1 Vestal as we work to re-build the walk. With a special thank you to Barber and Sons and Lydon and Sons. JNLF

1875, June 20. A meeting of the Officers of Congress was called at the house of Mrs. Hanaford, 5 Summit Ave., Jersey City. The weather was intensely cold. I went to New York on the 19 th and stopped with my friend Mrs. Clapp, 100 W. 54 St . . . .It was a question who should preside. Mrs. Hanaford thought the Chairman of the Executive Committee should and I had been told that I should, etc. The question was decided by the non-arrival of the Chairman of Ex.Com. I called them to order at an hour after the time appointed. Of course I made many blunders, as I have never presided before, but I continued for 4 hours. We did a few good things . . . The thing most weighing on Maria’s mind at this meeting was the looseness of membership for the Congress. She felt people were not being vetted properly in some areas of the country and thus they may allow in “undesirables.” I would take this to mean women who were not entirely behind the cause of the Congress and the Association for the Advancement of Women. I am not surprised by her suspicions and likely she was correct – one could see naysayers gaining access to this group and trying to destroy it from the inside. The women’s rights movement would have many schisms within it as people disagreed and broke into smaller factions.  Another important thing to point out is that Mrs. Hanaford is Nantucket-born Phebe Coffin Hanaford. Raised a Quaker, like Maria, Coffin Hanaford would become the first woman Universalist minister in New England – among many other firsts. She grew up with Maria, attended and taught at the Coffin School here on Nantucket, and was a founding member of another women’s organization, Sorosis, which Maria was also a founding member of. It’s nice to see two sister Nantucketers continuing to work together as adults – far from home! JNLF

After many, many years of service, our picket fences are getting a much needed replacement. We are starting with the fence on the north side of Vestal Street along the front of the Maria Mitchell Vestal Street Observatory (MMO). This fence is being replaced with part of a grant from the Community Preservation Act. The grant was for the exterior conservation work and landscape issues related to the MMO. The current fence is approximately thirty-five years old so it did rather well. It had replaced a very old fence – one I wish we had kept! But it had been hit many times by cars and had so much paint on it, they decided to replace it. We have small part of that fence still and we will be reproducing it for all the fences we are replacing here on Vestal. The fence is not much different than a normal picket here on island – it’s a hair shorter but it also has a sort of rolled top – not this cut style. I am excited to have this fence back! The new fences are being built by Michael Gault – owner of Gault Woodworking and a Nantucket Preservation Trust Traditional Building Methods award winner. His work is incredible – and lucky for us – he loves building fences!  So keep an eye out – work has begun already. The south side where the MMA Research Center and Hinchman House are located will be done in the fall in the same style. JNLF
