Nantucket Maria Mitchell Association Welcomes Dr. Valerie Hall Featured Guest for August Science Speaker Series

August 2, 2023

NANTUCKET, MA—The Nantucket Maria Mitchell Association (MMA) announces that it will host Dr. Valerie Hall, Ph.D., as a featured presenter for its Science Speaker Series. Her presentation will take place on August 16 at 6 pm. It will be presented in-person at the MMA Research Center at 2 Vestal Street and via Zoom. This event is free to all.


This feature presentation will give an overview of the biology of the bay scallop and its unique fishery. Dr. Valerie Hall, Maria Mitchell Research Associate, and nine of her students: Ellie Kinsella and Gray Simanson; Sophia Beni, Gus Simanson, Sayam Thapamagar, James Borthwick, Kate Kinsella, Julia Winsor, and Aiden Haase will first describe the biology of the Nantucket Bay Scallop, Argopecten irradians. This presentation will cover the Bay Scallop classification, habitat, distribution, ecological niche, life cycle, reproduction, timing of spawning, predators, parasites, and environmental hazards the species faces. Students will then describe the laboratory and field program which is now in its eighth year at the Maria Mitchell Association. They will also share their experiences on scallop collecting trips in addition to the process of dissecting and preparing the reproductive tissue for histology (the process by which microscope slides are prepared from thin sections of gonad). Finally, students review their examination of prepared slides to determine the degree of spawning of each collection and co-relate their findings to water temperature. Students not only learn how to collect and analyze data but also to master the biology of this species while they gain experience and skills working as a part of a team in a research laboratory setting.


Dr. Valerie Hall has lived on Nantucket for 46 years. After a 35-year career teaching high school science, mostly on Nantucket, she earned her Ph.D. in Fisheries Oceanography at the University of Massachusetts’ School for Marine Science and Technology in 2014. She then began a research and mentoring program at the MMA which has just completed its eighth summer. During that time, Dr. Hall has worked with over 80 high school and college students alike. Students earn community service hours and have benefitted immensely from Dr. Hall’s program, many of them asking to return for subsequent seasons.

This presentation is complimentary and held both in-person, at the MMA’s Research Center located at 2 Vestal Street, and via Zoom, please pre-register.



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.

Maria Mitchell In Her Own Words

By Jascin N. Leonardo Finger • May 19, 2025
May 27. {1857} There is this great difference between Niagara and other wonders of the world, that is you get no idea from descriptions or even from paintings. Of the Mammoth Cave you have a conception from what you are told, of the Natural Bridge you get really a truthful impression from a picture. But Cave and Bridge are in still life, Niagara is all activity and change. No picture gives you the varying form of the water of the change of color; no description conveys to your mind the ceaseless roar. So too the ocean must be unrepresentable to those who have not looked upon it. Maria Mitchell would tour the Mammoth Cave and the Natural Bridge during her trip to the southern United States as Prudence Swift’s chaperone – I have written of these travels and Prudence before. Niagara Falls is a place she likely saw on her way to visit her younger sister Phebe Mitchell Kendall, who once lived with her husband in Pennsylvania. I was a bit surprised that she feels the way she does about the Cave and Bridge being well-represented by images but I do kind of se her point. But Niagara, the ocean, any moving body of water – she is right. You don’t fully comprehend it until you hear it, touch and taste it, see its colors, and feel it splash, sprinkle, or mist across your face. Niagara certainly mists across your face – sort of like a breezy day at the beach and the salt mist that slowly builds across your face and coats the beach grass so that it shimmers in the sunlight.

Lily of the Valley

By Jascin N. Leonardo Finger • May 12, 2025
I have been watching it. Waiting. Today, I was rewarded with the scent as they have now started to open. From late fall, all through the winter and early spring, there is a very large patch of dirt with traces of roots and purple-like portions of some sort of plant. Then, they slowly start to send their shoots forth – up from that dusty pile of dirt come little greenish pips that become the leaves. Then, you start to see the stems tightened against the leaves and then lovely chartreuse buds are visible that then turn to white and slowly open from top to bottom. As soon as they star to open, I wait. Knowing that one morning I will walk by soon and then I will get a delicious waft of Lily of the Valley. I have written about this patch at the Mitchell House before. I have always been fascinated by the fact that these grow in full sun – they have no shade whatsoever. And this patch is old. I’m not sure how old – I do not think late nineteenth century but possibly – or maybe very early twentieth century. We have one or two images in the collection from the early 1900s but one does not show the ground, and the other not so much either. I also think this is one of the earliest flowering patches of Lily of the Valley on island – let me know if you’ve seen others this early. And in FULL sun to boot! But in any case, today was the day – May 5, 2025 – that I got the first waft. Saturday when I was here, they were not ready yet. But now, they are! And when I smell it, I know why it was my mother-in-law’s favorite flower. JNLF

Nantucket Maria Mitchell Association Welcomes Richard Sotell, CFP as Featured Guest for May Science Speaker Series

May 6, 2025
NANTUCKET, MA—The Nantucket Maria Mitchell Association (MMA) announces that it will host Richard Sotell, Certified Financial Planner (CFP) as its May featured Science Speaker Series presenter. His presentation “The Science of Money: The History of Tariffs and Taxation” will take place on Wednesday, May 21 from 7 – 8pm EST. The presentation will take place on Zoom and pre-registration is required. This event is free to all. Join the MMA and financial expert and top 401(k) advisor, Rich Sotell, for a discussion on the history of tariffs and taxation. Taxes and tariffs have played a major role in shaping nations. In America, British taxes and tariffs on goods like tea and paper helped spark the American Revolution. Later, U.S. tariffs were used to protect young industries from European competition. Today, taxes fund public services such as education, healthcare, and infrastructure, while tariffs are still used strategically—sometimes to encourage domestic production, other times as tools in international negotiations. Rich Sotell will discuss in detail how taxes and tariffs began and their relationship to our global economy. Sotell has been involved in the financial industry since 1975 and is a founder of the Kraematon Group and is responsible for the operations of the 401(k) division. He has developed marketing programs for both banks and mutual fund companies in the areas of IRA and 401(k). Sotell is a tax law expert concerning distributions from qualified retirement plans and IRA’s. He has lectured on these subjects to insurance company executives, on radio, and at several professional education programs. Sotell is currently a contributing member to several high level 401(k) advisory boards in the mutual fund and payroll industries. He was named by the Financial Times as a 2015 and 2016 “Top 401 Retirement Advisor,” a list of 401 elite professionals specializing in U.S. defined contribution plans. Sotell earned a Bachelor of Arts degree from Colgate University in 1975. His professional designations include Certified Financial Planner (CFP), Investment Company/Variable Contracts – Series 6 Registration, and a Uniform Security Agent – Series 63 Registration. The Kraematon Group is a leading 401(k) consulting firm headquartered in Wellesley, MA. In addition to providing 401(k) consulting services to Allied American Insurance Agency and its former parent Arbella Insurance, Kraematon consults with over 3% of all Massachusetts based public companies regarding their 401(k) plans.
