Miss Mitchell’s Students: Margaretta Palmer

Jascin N. Leonardo Finger • November 12, 2019

Standing under the canopy of the stars, you can scarcely do a petty deed or think a wicked thought.


Maria Mitchell’s influence reached far and wide and remained strong through many generations of not just her own students but the students of her students.  Her immediate galaxy was of course the women who took her astronomy and mathematics classes at Vassar College.  She instilled in her students a lifelong love of learning and the knowledge that as women, they had the power, strength, and knowledge to be the future of women scientists and educators in the world.  Some would go on to great accomplishments and some would go on to quietly influence other young learners of the world – spreading Maria’s legacy farther afield.


Over the next few blogs, I would like to share with you some of Maria Mitchell’s students.


The third is:


Margaretta Palmer, 1862-1924

A classmate of Antonia Maury’s, Palmer graduated in 1887 and served as Maria Mitchell’s assistant for that first year after graduation.  She had taken several of Maria’s astronomy classes.  In 1889, she was hired by the Yale Observatory to serve as an assistant– mirroring the program her classmate, Maury, was doing at Harvard.  She was among the first group of woman admitted to Yale for graduate school, receiving her Ph.D. in 1894 in mathematics – the first woman to earn a PH.D. in mathematics and the first of seven women to earn Ph.D.’s from Yale.  Her    thesis – a recalculation of her professor Maria Mitchell’s comet of 1847 – was a perfect match for this astronomer and mathematician and likely a nod to her Vassar mentor.  Her focus was in computational astronomy which led her to calculate the orbits of many comets that were previously discovered including several by English astronomer Caroline Herschel who was forced, due to her sex, to give much of the credit for her astronomical work to her astronomer brother, William Herschel.  Palmer worked at Yale for her entire career – weathering many tensions and internal fighting – but was able to publish several articles of her own, as well as numerous other publications that she co-authored.

It used to be that whatever the deer or bunnies ate at my home garden, I could plant with relief in Town in the Mitchell House garden. But, over the years, it has become more difficult as we have a plethora of bunnies – multiple complaints made here in this blog – and deer that are now coming into Town year round. They have resorted, in winter, to eating ivy and while ivy is considered invasive, it has been a long-time, reliable ground cover in Town – as in a hundred or more years. Now, we have voles – which do have cycles where their population booms for a year – or two – but we have not had them in the MMA gardens at least in my memory. Now, we do and I worry about them devastating the garden in front of the Observatory which is a large, native species garden we have worked on for many years. I know climate change is definitely playing a role – it’s affecting the birth cycles of voles and allowing them to have potentially more broods. Its also potentially affecting some of their predators that may not be as prevalent and thus fewer voles are being eaten. In any case, we have tunnels galore, which is why I was happy to have ONE blossom on the heirloom morning glories I plant for Mitchell House every spring. Out of 500 or more seeds – I got one lonely blossom! The voles are attacking my own personal garden – the last two summers – and I have lost many of the mainstay lilies and perennials that have been there for forty years – or they have shrunken due to their root systems being undermined and eaten. Roses are failing too. So if anyone has better ideas then solar hummers, live trap, kill trap, or Juicy Fruit gum – let me know – poisons not allowed! JNLF Update: Got four more blossoms - but still!

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. ###
