Interior Conservation Work Has Begun!

Jascin N. Leonardo Finger • October 28, 2024

With a new grant from the Community Preservation Act (CPA), we have now moved inside – to begin work on the interior of the historic components of the Vestal Street Observatory. We are very excited!


After much conservation work completed to the exterior, with a CPA grant as well, we have a weather tight exterior which allows us to start the interior work. In the Astronomical Study, original plaster – possibly with a skim coat of parging – walls have been cleaned up. When I note cleaned – it’s the removal of any loose paint only and no walls have been filled so all that original 1922 “bumpiness” and pitting of those walls remains. A primer coat is being applied to the walls and then we will return to the original cream color on the walls. The circa 1987 blue wall-to-wall carpeting has been removed, as well as the layer of tiles from the 1950s or so. We have revealed the original 1922 wood floor which is beginning its conservation as well. Unfortunately, there was a layer of tarpaper placed between the wood floor and tiles, with a TON of glue, so the work on the floor is a bit more extensive than we had originally hoped. While we looked at some areas under the carpet initially, it did not reveal the extent to the damage of the wood floor. But Adam Zanelli of Nantucket Heritage Painters, and Pen Austin, lime plaster and historic finish expert extraordinare, have worked together to figure it out. Adam and Pen are also working out the final planning phases of work to the original woodwork. We will only be touching areas of loss or damage, matching the tint of the wood, and applying shellac which is what most of the woodwork is coated in. 


In the Pillar Room and Dome Room, they are also working to deal with the layers of paint (mostly from the last thirty years) and in the cellar dealing with the parging that is on most of the walls. The parging was likely for two reasons. To make the room more inviting and cleaner – it was used for storing glass plates and had the boiler way back in the day (sounds horrific but I believe they thought the boiler would keep the glass plates of the night sky dry – and it likely did) and to keep the room waterproof (which it did at first but it has not in many years and has been failing). The parging is likely not original – it seems to be a different vintage and make-up from the one up in the Study.


There is more to come – and a lot of woodwork in other areas that will get the same treatment as the Study. We also have concrete floors with some issues to address, as well as electrical and a new HVAC system. So stay tuned!

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)!

NANTUCKET, MA—The Maria Mitchell Association (MMA) invites the community to “Dark and Quiet: Astronomy in the Age of Satellite Constellation” presented by Dr. Joshua Reding for its April Science Speaker Series. This free presentation will take place Wednesday, April 15 from 7 – 8pm on Zoom. In the past decade, the number of active satellites in Earth’s orbit has grown by a factor of 10. This breakneck growth in the commercial space industry has turned entrepreneur, investor, and policymaker eyes to the skies, but in the process has boxed out the historic stewards of the space domain: scientists. Explorers and pioneers across human history learned that uncharted territory hides unprecedented challenges, but the consequences of decisions made towards occupying the “final frontier” do not abide by international borders. Space operators therefore ignore the warnings and concerns of scientists not only at their own risk, but at the risk of everyone living under increasingly crowded skies. In this conversation, Dr. Josh Reding will explain how astronomers are trying to inform and guide policymaking for the rapidly changing space environment, both informally through volunteer action and advocacy and formally in domestic and international policy forums. Dr. Reding is an optical astronomer by training and now a radio spectrum manager by profession. He completed his B.A. with a double major in Astronomy-Physics and Philosophy at Colgate University, and his M.S. and Ph.D. in Physics from the University of North Carolina at Chapel Hill. His research investigated unusual white dwarf stars that likely formed in stellar mergers as “failed” supernovae and he has also designed astronomical instrument components and installed them at world-class observatories. Concurrent with the completion of his Ph.D., Reding began his professional science policy career as a North Carolina STEM Policy Fellow in the NC Department of Commerce’s Office of Science, Technology & Innovation. He was then selected for the American Association for the Advancement of Science Science & Technology Policy Fellowship, which places scientists in federal offices as expert contributors to ongoing agency missions. This event will be held via Zoom. Pre-registration is required. To register for the free, virtual event, use the registration link: https://us06web.zoom.us/webinar/register/WN_5MoAybp5QHCasQ0QE5xmgQ#/registration The Science Speaker Series is generously sponsored by the Maria Mitchell Association’s lead sponsor, Bank of America. The Maria Mitchell Association was founded in 1902 to preserve the legacy of Nantucket native astronomer, naturalist, librarian, and 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 professor of astronomy at Vassar College. Maria Mitchell believed in “learning by doing” and today that philosophy is reflected in the MMA’s mission statement, programs, research projects, and other activities. The Maria Mitchell Association operates two observatories, a natural science museum, an aquarium, a research center, 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. ###
