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!

Ice Whale

By Jascin N. Leonardo Finger • March 2, 2026
It’s sort of funny what Mother Nature does. Granted, in this case, she had a little help by shovel or plow. But as I made my way up Vestal Street a week ago or so, after the first round of eight inches of snow or so, I noticed this ice shape on the front stoop of the Mitchell House. To me, it looks like a whale with its tail up in the air! I think it’s sort of appropriate for this front stoop so I decided to share! JNLF

Nantucket Maria Mitchell Association in Collaboration with Nantucket Dreamland Announce "Doktor Kaboom" Under Pressure!" Coming to Nantucket in March

February 18, 2026
NANTUCKET, MA— The Maria Mitchell Association, in collaboration with the Nantucket Dreamland, invites the community to two unforgettable and entertaining performances featuring Doktor Kaboom: Under Pressure! on Friday, March 13 and Saturday, March 14. Doktor Kaboom’s interactive Science Comedy shows engage audiences of all ages. In Under Pressure!, Kaboom illustrates physical science concepts that are also metaphors for real-life mental and emotional pressures, validating what students may feel, while sharing tools for dealing with life’s challenges. Blending big ideas, explosive demonstrations, and humor, Kaboom keeps audiences riveted with interest and rolling with laughter. Hailed as, “part Mister Wizard, part Mr. Rogers,” Kaboom delights patrons with curiosity, creativity, and charm. Both performances are FREE to the public. This event is possible due to a grant from the Remain Nantucket Fund at the Community Foundation for Nantucket. Reflecting on both the impact of the performance and the partnerships that made it possible, MMA Executive Director, Joanna Roche, shared, “A heartfelt thank you to the Community Foundation for the generous grant that made it possible to bring Doktor Kaboom to Nantucket, and to the Nantucket Dreamland for hosting this extraordinary performance. I’ve known the good Doktor for nearly twenty years, and I have no doubt that his unique blend of humor, magic, and science will not only make you laugh, but also leave you with a renewed sense of wonder and a deeper connection to the world around you.” The Friday performance will be followed by an Ice Cream Bar, generously sponsored by Island Kitchen, and a photo opportunity with Doktor Kaboom in the Harborview Room. Event Details: • Dates and Times: Friday, March 13 at 7pm and Saturday, March 14 at 3pm • Location: Dreamland Theatre, 17 South Water Street • Special Offering: Friday, March 13 – Post-performance Ice Cream Bar in the Dreamland Theatre Harborview Room, generously sponsored by Island Kitchen, plus a photo opportunity with Doktor Kaboom • Tickets: Available at https://www.nantucketdreamland.org/events/doktor-kaboom-under-pressure • Cost: Free This community event kicks off another free collaborative event, the annual Nantucket STEAM Festival, taking place Saturday, March 14, 2026 at the Nantucket High School Gymnasium from 10am – 2pm. This event features hands-on activities celebrating science, technology, engineering, art, and mathematics from over twenty community organizations. A sensory-friendly half house begins at 9:30am. Doktor Kaboom! was created, and is performed, by actor and comedian David Epley, who has discovered two passions in his life: science and mathematics. Epley first explored his love of hands-on learning, chemistry, and physics at the North Carolina School of Science and Mathematics and later studied at the university level, exploring a degree in Chemical Engineering. Epley, a performer for over twenty years, has reached over 2,000,000 students and families, and has performed over 2,000 live shows worldwide. Epley lives in Seattle, Washington. About the Nantucket Dreamland: The Nantucket Dreamland is a nonprofit organization dedicated to enriching the cultural and intellectual life of Nantucket by providing year-round films, educational programs, and a venue for community activities that engage Nantucket in the evolving world of entertainment and education.

About the Maria Mitchell Association: 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. ######

Maria Mitchell In Her Own Words

By Jascin N. Leonardo Finger • February 17, 2026
1881, Feb. 26. Miss Whitney read Frances Power Cobbe’s “Lectures to Women” aloud to me. In the main they are excellent. I agree at almost every point. What she says about the duty of women in veracity, in cultivating both physical and moral courage, etc., in demanding not “favor but justice” . . . Mary Whitney would become the first president of the Nantucket Maria Mitchell Association. She was one of Maria’s first students and ultimately her replacement at Vassar College. She also took over for Maria when she left the College for a brief illness in 1880. On her second trip to Europe in 1873, Maria would seek Frances Power Cobbe out at her home. A suffragette, Power Cobbe was a philosopher and writer among other things, including an animal rights activist when it came to experimentation on animals. Born into a wealthy family in Ireland, Power Cobbe would travel in Europe about the same time as Maria did in 1857, meeting some of the same people Maria would meet such as Mary Somerville (Maria’s hero and an astronomer, mathematician, scientist, and polymath) and Harriet Hosmer (sculptor). I should not note this but Maria wrote about Power Cobbe’s large head –further stating that being a large woman, she would have a large head. Reviewing images of Power Cobbe, I hate to say it but I cannot disagree – with my apologies to Ms. Powers Cobbe. JNLF
