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!

Maria Mitchell In Her Own Words

By Jascin N. Leonardo Finger • September 21, 2026
Sept. 24, 1881. . . . Mr. I. {van Ingen} thinks that not a person on the Board of Trustees would approve of the clause in Mr. Vassar’s will which objected to women as occupants of chairs. Just months before, Maria Mitchell had written a letter describing the controversy surrounding the bequest of Matthew Vassar to the college he founded. The large sum was separated out within his will, including the establishment of department chairs. The bequest for this action, however, did not allow for women professors to have a chair. Quite shocking for a women’s college but then, there were early trustees in the College’s founding who believed that women professors should not exist at Vassar! Maria would be the first professor Vassar hired – male OR female. JNLF

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 female 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. ###

Hoop Rolling

By Jascin N. Leonardo Finger • September 14, 2026
Do you know what these Mitchell House Junior Historians are doing? It is a good old-fashioned round of hoop rolling. And, they had a lot of fun learning how to use them down at the Coffin School one day. Hoop rolling or hoop trundling were popular from very early on and well into the twentieth century. By early on I mean Ancient Greece even. It’s on ancient pottery and was not limited to children! Native Americans, ancient Rome, 16 th century England – it’s been known by different names, taken various formats, played by various ages, and played through various ages. In the nineteenth century, both boys and girls did hoop rolling – and it was likely seen as a more “ladylike” active game that girls could play. I’m assuming that is likely the reason why several women’s colleges still have I tradition of rolling hoops. We use these sometimes in the summer during our weeklong Mitchell House children’s program – Junior Historians. Do not be too surprised if you see me out on the lawn on Vestal Street practicing on warm days this fall, winter, and spring! Got to get up to speed! JNLF
