Maria Mitchell Vestal Street Observatory Update

Jascin N. Leonardo Finger • November 21, 2022

It has been a bit of time since I updated you on the conservation project at the MMO. Things are moving along although we are still confronted – as everyone else is – with supply chain issues. 


But, the mason has replaced most of the cellar lintels. The iron had rusted and started to cause shifting in the bricks. He has painstakingly dug them out and then replaced the iron lintel with steel. He will then fill them and re-brick them with the existing bricks. 


He has also been working on the main floors iron lintels. These have proved more of an issue for removal. The doors and windows in the Astronomical Study addition have large stones over them and then the lintel is found behind the stone. The stone, while smooth on the front is rough on the sides and back and when they filled in around and behind it with grout that rough stone really did a great job of adhering to the grout. And, they filled in from inside the building before it was finished so its packed and stuck in there very firmly. He has to work slowly and carefully so he doesn’t break the stone because it will be reused – and if it breaks we are never going to be able to match it. So, it’s a tough and slow process. And these stones over the windows and doors weight hundreds and hundreds of pounds so the weight is another issue.  You will note where he has dug out around the lintel over the door. He is trying to save all the brick to re-use it so it matches. And, our Observatory is made of three layers of brick – that is, it is three bricks deep.


This conservation work is funded with grants from the M. S. Worthington Foundation and the Community Preservation Act.

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.

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
