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.

A re-blog from years past. The item you see here is a small piece of what once was. Upon her visit to Europe as a young woman’s chaperone in 1857 –1858, Maria Mitchell visited many of the major observatories of Europe and met many of the movers and shakers in the scientific, art, and literary worlds of the continent. While Caroline Herschel (1750 – 1848) and her brother, Sir William (1738 – 1822), were long dead, Maria was able to meet Caroline’s nephew (William’s son), Sir John Herschel (1792 – 1871). All three were astronomers, though Caroline found herself having to give credit – or have her brother accept credit – for much of her work because she was a woman. She has often been credited with the being the first woman to discover a comet. She was likely not – and the other woman who was the first lost credit through history as she had to “give” her comet discovery to her husband. See a pattern? Caroline was just one of many women in a long line of, “She couldn’t possibly do that – she is a woman!” As Maria once said, “But a woman, what more could you ask to be?” But back to this small item. It was a page from one of Caroline Herschel’s notebook’s, torn from its home by John Herschel to serve a s a memento for Maria of her visit to the family’s home. Maria was a bit shocked but . . . she took it! Over the years, the paper tore and ripped and just crumbled away until Maria finally decided that to save it, she needed to past it into one of her own journals. And thus, we have what we have. I assume Caroline’s notations refer to her brother William – “Wol” and Woll.” It could be an “I” but it really looks like an “O.” She is considered the world’s first professional woman astronomer – she would be compensated for her work after some time – and she warrants a greater look at – too much for a blog. So I encourage you to go take a look at her. Maria would want you to! JNLF

I am not so sure our founders would love that title but the image is of the Maria Mitchell Vestal Street Observatory (MMO) “from the rear.” I love this image as it is really the only one we have – unless you count the one that is taken from farther away and from further into the backyard of the Mitchell House. That one allows you to see the natural slope of the Mitchell House back lawn which would be altered when they added the Curator’s Cottage. Both of the images were taken before the Curator’s Cottage was added at the back of the Mitchell House in the early 1930s – and this one you see here was taken before 1922 when they added the Astronomical Study onto the MMO. It also shows the original dome – which was copper – before it was replaced in 1951 – which is the current dome. The copper did not hold up to our climate here – salt spray, damp, fog. But the new one, shipped over from England, has held up well. The current dome was donated by Margaret Underwood Davis (MMA board president at the time), in memory of her son, Cushing Davis who was an amateur astronomer. Margaret Davis served as president from 1930-1946 and again from 1949-1953. The image tells you some other things too. For instance, the grape arbor behind the Mitchell House is supposed to be Peleg Mitchell’s (Maria’s uncle) grape vine – I have blogged about it several times before – and you can see it in this image. You can also see how the Milk Room connects to the 1850s kitchen. The 1850s kitchen was added by Peleg Mitchell Jr and it’s the first little wart you see with the white pipe attached. The next wart is the Milk Room – also added by Peleg – it’s the one with the shutters on the window. Both still exist it’s just the Curator’s Cottage was attached in the 1930s. You will see another chimney too. It appears alongside the white pipe. That is likely the original chimney to what is now the Astronomer’s Cottage at the MMA. We acquired the Cottage in the 1920s but I believe all of the additions, and the removal of the chimney, were done before we were given it.  Fun! JNLF
