Update: Conservation at the MMO

Jascin N. Leonardo Finger • July 18, 2022

Conservation of historic buildings is a slow process. Much of it comes from trying to match the original materials so that we can make sure the conservation work is done properly, that it matches in color, and that it works with what exists. For example, painting latex paint over a lime-based paint: not a good idea. It is not historically accurate but also that latex is not going to adhere to the lime wash properly and at some point, you will have a mess that you are re-doing the right way.


In the case of the Maria Mitchell Vestal Street Observatory, the grout (cement) is very coarse. It’s full of small pebbles and broken pieces of stone (see image). The main dome was built in 1908 and the addition to the right of it was completed in 1922. When I joke that it looks like they went to the beach to make the grout mixture, I am not entirely sure it is a joke!


In any case, this is not something – the lime or this particular grout – that you buy off the shelf. The mason has to make it – match the color, the texture/coarseness, the pebble-like material and colors in it, the mixture. Thus, the amazing island mason, Wayne Morris – who has been working on this project and also did our conservation work at the MMA Research Center – has spent countless hours collecting stones and digging through stones he has in his masonry yard. Once he has a good amount and ones that match what is on the MMO, he pulverizes them to match the size of the pieces found in the existing grout on the building. He actually created a special tool to do this. Because, that’s how he works.



So, now that he has a good supply, he has been focused on the back side of the building dealing with the cracks and places that the grout has spalled and fallen out. He is now attending to the front of the building, thus more staging. Once those areas are dealt with, he will replace the iron lintels above the windows. These have rusted because of water getting in. They will be replaced with steel that will not rust, expand, and then cause cracking. He will also be addressing the “parapets” – rebuilding them where needed – and attending to the copper and the flat room on top of the 1922 addition.

Nantucket Maria Mitchell Association Welcomes Dr. Jackie Milingo, MMA's Director of Astronomy, as Featured October Science Speaker Series

October 2, 2025
NANTUCKET, MA— —The Nantucket Maria Mitchell Association (MMA) announces that it will host its new Director of Astronomy, Jackie Mlingo, PhD., as a featured presenter for its October Science Speaker Series. The presentation will take place on Wednesday, October 15 at 7pm in person at the MMA Research Center, 2 Vestal Street, and via Zoom. The event is FREE to all. Have you ever noticed the dark spots that sometimes appear on the Sun’s surface? These “sunspots” are just one example of star spots—mysterious patches that appear on stars across the galaxy. Far from being simple blemishes, star spots reveal the powerful magnetic forces at work inside stars, forces that also drive solar storms and shape the space weather that can impact entire planetary systems. In this talk, Dr. Milingo will share her research on star spots and how she uses them as a window into teaching undergraduates the process of scientific discovery. She will also explore how science can reach far beyond the classroom—bringing STEM into everyday spaces and sparking curiosity across communities, from kindergartners to lifelong learners. Dr. Jackie Milingo is an observational astronomer who earned B.S. degrees in Physics and Astronomy from the University of Kansas, and a Ph.D. in Astrophysics from the University of Oklahoma. Her research is currently focused on understanding magnetic activity cycles in sun-like stars through long-term studies of starpots. Dr. Milingo joins the MMA after a year-long AAAS Science and Technology Policy Fellowship at the U.S. National Science Foundation, where she was a Fellow in the Office of Legislative and Public Affairs, as well as the Astronomy Division in the Math and Physical Sciences Directorate. Before her fellowship, she was a professor in the Physics Department at Gettysburg College for over twenty years where her work included mentoring undergraduate research students. Dr. Milingo joined the staff of the MMA in early September after a year-long, worldwide search for a new astronomer. She becomes the eighth MMA Astronomer and Director of the Astronomy Department of the MMA since Margaret Harwood, the MMA’s first astronomer, served from 1916 to 1957. Dr. Milingo has spent her career committed to generating transformative experiential learning opportunities, contributing to public education and outreach, removing barriers for students, and changing the conversation and learning spaces in astronomy, physics, and STEM in general. This event will be held both in person and via Zoom. Pre-registration is required to attend either option. To register for the free, in-person event, use the registration link below: https://112458a.blackbaudhosting.com/112458a/October-Science-Speaker-Series--Dr-Jackie-Milingo To register for the free, Zoom option, use the registration link below: https://us06web.zoom.us/webinar/register/WN_5q4kXF2rRHi8iWbFPkLN5w 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. ###

Maria Mitchell In Her Own Words

By Jascin N. Leonardo Finger • September 29, 2025
Sept. 25, 1854. . . . The best that can be said of my life so far is that it has been industrious, and the best that can be said of me is that I have not pretended to what I was not.  I think of two things when I read this. One is that Quakers believed in being industrious and not wasting time. The second point makes me think immediately of Holden Caulfield – The Catcher in the Rye if you don’t know that character’s name – and his various references and discussions to “phonys” as he refers to them though Maria’s mention here is not entirely in the same vain. A materially successful Quaker was one who was living “in the light,” as Quakers referred to it. Even if gifted with material wealth, Quakers still lived frugally and were a hard working group of people. As Hector St. Jean de Crèvecoeur noted, “Idleness is the most heinous sin that can be committed in Nantucket . . . for idleness is considered as another word for want and hunger.” If you were not productive and industrious, you would starve – and it would affect others in the community since isolated Nantucket acted as a corporate family economy – everyone was relying on one another for survival. While Maria is also not necessarily going to this depth of industrious it is a Quaker ethic that was strongly imbued in her. She certainly was a hard worked with numerous accomplishments to her name and many different projects completed even by 1854 at age thirty-six. And don’t forget October 1 st is the anniversary of Maria’s comet discovery – October 1, 1847. JNLF
