Miss Mitchell’s Students: Mary Watson Whitney

Jascin N. Leonardo Finger • September 30, 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 first is:


Mary Watson Whitney, 1847-1921

Born the month before Maria discovered her comet, Mary Whitney would be in Maria’s first Astronomy class at Vassar.  She would also serve as her former teacher’s assistant and later her replacement when Maria left Vassar in 1888.  Like Maria, Whitney had a love for the natural world and was an excellent mathematician; she grew close to both Maria and William Mitchell.  After leaving Vassar, Whitney taught school, attended – by invitation – mathematics lectures at Harvard as the only woman allowed to do so, and would be named the first president of Vassar’s alumnae group.  Vassar awarded her a master’s degree in 1872.  She travelled to view the eclipses with Maria and when Maria became more frail, returned to Vassar to serve as her assistant.  She accepted a research position at Harvard’s observatory giving it up to return again to Vassar to take Maria’s place where she worked until her retirement in 1915.  Whitney would serve as the Nantucket Maria Mitchell Association’s first president.

May 6, 1878 Between the clouds, Miss Spalding obtained 7 photographs of Mercury on the Sun. It is comfort to me to be able to plan and do a new kind of work. The large telescope worked better than usual, Clark having just been to the Observatory. Clark, as in Alvan Clark, a man who would become the premier telescope maker in America and who built Maria Mitchell’s 5-inch Alvan Clark refractor that she purchased from him (after working with him to build it per her specifications) with money gifted to her from “The Women of America” led by Elizabeth Peabody. More than likely, it is this telescope she is referring to as she did use it in the Vassar College Observatory with her students – and it is also taking center stage in photographs, along with her (first her father’s) Dolland telescope.  Maria had decided she would photograph the Sun on every clear day, and this was one of those results. She would use these images, with her students, to study sun spots and their changes. With her students, Maria would photograph the transit of Mercury as noted above. She would also photograph the transit of Venus a few years later with her students. JNLF

And with it, some of the heirloom daffodils I purchased for the Mitchell House last fall. A place was recommended to me by two longtime friends of the MMA and gardeners extraordinaire. It is called Old House Gardens. I ordered a small amount as we now have a plethora of voles on Vestal Street – I believe I complained about them here last year. They won’t eat daffodils so I got a few of “Butter and Eggs” (1777) and “Conspicuus” (1869) as either of these could have appeared in William Mitchell’s gardens. They were not listed in a letter from John Quincy Adams that I have mentioned before. But, Adams was not here visiting the Mitchell family when the daffodils would have been in bloom. The one pictured here is “Butter and Eggs” not completely unfurled. JNLF

April 1878. The conference of Woman’s Congress officers met in Washington. Because we had one member in Washington we were invited to meet in that place. I went on at a great expense of time, money and strength . . . . We were in session at least nine hours. I think that more than half of that was used by Mrs. Spencer and Mrs. Sayles. The only motion which I carried through was to pay the Secretary $200 . . . In 1878, that was a long train(s) ride to Washington, DC from Poughkeepsie, NY and Vassar College. If Maria seems perturbed, I am sure she was. As president of the Association for the Advancement of Women, and thus the Congress, she had to be at the meeting. But it appears she did not get much say in the nine hour meeting. This was also a long trip to take when she had another, even longer trip coming up in July of 1878. In that month, she would travel with students and her sister, Phebe, out west to Colorado to view the eclipse and that train and wagon ride I am sure was weighing on her mind – not just the physical trip but making her way for an important eclipse viewing event.
