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.

Mallow!

By Jascin Leonardo Finger • August 31, 2026
I’m sure you’ve seen it as you trek about the island – near the beaches and ponds. This image is of the swamp or marsh mallow that we have on Vestal Street in our garden out front of the Observatory. It can grow in drier places – though it’s not as lush as at Capaum Pond or out in Quaise. It’s in the Hibiscus family – and is fairly tropical looking and always a delight to see.  “When in bloom, one of the most showy plants of the Island, for a mass of the magnificent, large flowers on the edge of a blue pond causes one’s heart to thrill at the wealth of deep pink colour . . .” from Nantucket Wild Flowers, Alice O. Albertson (cousin of Maria Mitchell), 1921. JNLF

A Piece of a Clay Pipe

By Jascin N. Leonardo Finger • August 24, 2026
I have always wanted to find a piece of a clay pipe. I know – weird – but if you have ever read any of my blogs here for the MMA then you know I have a thing for pottery shards. I sort of figured I would not find a piece of a clay pipe – not even a piece of a stem. But the other day, walking in a place where I have found quite a few shards, I found a piece of clay pipe! Now, I’m not talking about water pipes – I am talking about tobacco pipes. And I know very little about clay pipes. Yes, I am a curator of a historic house museum, but this family did not smoke. They were Quaker and among the many things they abstained from, tobacco was one of them. Therefore, I am not up on clay pipes so I am doing a bit more research.  For one, age can be determined by the width of the hole inside the pipe. So based on this one, I would say it’s fairly late. Since they were so fragile, and those holes pretty small, if it got filled with tobacco, the person just broke off the stem creating a shorter pipe and one that was not clogged with tobacco. Apparently, stems could be recycled – in fact, 15,000 broken stem pieces were uncovered at a historic walkway at Colonial Williamsburg – they were used as fill! And pipes were made into the early twentieth century – falling out of favor around World War One. It makes sense – they were cheap, easy to make, and affordable. Typically, one could last a few years – unless you dropped it of course. An,d pipes were used by men, women, and (eh, em) yes, children. I can see that Nantucket may not have had a lot of tobacco smoking residents – not just that some were Quaker – but because of the Quaker influence. I t does not mean people here do not smoke – I just think there may have been fewer smokers on the island in the nineteenth century and earlier. JNLF

Maria Mitchell In Her Own Words

By Jascin N. Leonardo Finger • August 17, 2026
August 19 {1857}. There are four great men whose haunts I mean to seek, and on whose footsteps I mean to stand: Newton, Shakespeare, Milton, and Johnson. To-day I told the driver to take me to St. Martin’s, where the guide-book says that Newton lived. He put me down at the Newton Hotel, but I looked in vain to its top to see anything like an observatory. I went into a wine-shop near, and asked a girl, who was pouring out a dram, in which house Newton lived. She pointed, not to the hotel, but to the house next to a church, and said, “that’s it – don’t you see a place on the top? That’s where he used to study nights.” It is a little, oblong-shaped observatory, built apparently of wood, and blackened by age . . . .” Blackened no doubt by the wood ash and soot found in the air throughout over-crowded nineteenth century London. We always think about London being very foggy in the nineteenth century but frankly a lot of it was wood and coal ash as the nineteenth century grew older, particularly as factories developed and belched all of that into the air – think Sherlock Holmes in the 1880s. But Maria Mitchell, while starting in Europe as a young woman’s chaperone, also knew that this tour of Europe was a great learning experience – the equivalent of a college education she could not have. Doors were thrown open to her around Europe – in particular at all of the observatories that dotted the continent. She was not just well-known – she was famous. JNLF
