The Second Director of the Maria Mitchell Observatory

Most people work for a living. I live in order to work. It is what I love to do.

– Dr. Dorrit Hoffleit


In March 2007, Dorrit Hoffleit turned 100. She was a legend not only at the Maria Mitchell Association, but also at Yale University. Despite her retirement in 1975, Hoffleit continued to work well into her 90s, maintaining her office at the Yale Astronomy Department just across the street from her home and coming to Nantucket in 2005 to observe a transit of Venus – an event that Maria Mitchell witnessed in the 1880s at Vassar College. Dorrit Hoffleit attended Radcliffe College despite the fact that when she was eleven years old her teacher told her mother: "Dorrit is not as clever as her brother." And her mother replied: "What do you expect? She's only a girl."


Hoffleit’s career in astronomy began in 1928 as a research assistant at Harvard College Observatory, where she earned forty cents an hour to her male counterparts’ dollar an hour. She worked on photographic variables and spectral classification and took classes part-time in order to obtain her master’s degree. Encouraged by the Harvard Observatory director and her mentor, Dr. Harlow Shapley, Dorrit found herself again enrolled at Radcliffe in order to earn her Ph. D. In 1938, she was one of fourteen women to earn a Ph. D. from Radcliffe – the only one in astronomy that year. At commencement, she was awarded Radcliffe’s Carolyn Wilby Prize for the best original work in any department. Her thesis concerned the determination of stellar absolute magnitudes from an analysis of their spectra. She continued to work for Harvard Observatory until 1956, when she was appointed the director at the Maria Mitchell Association Observatory. The same year, she was offered a position in the Yale University Astronomy Department where she continued her work on variable stars, authored several books, wrote many papers, and made important contributions to the Yale Bright Star Catalogue. As director of the Maria Mitchell Association Observatory until 1978, Dorrit Hoffleit taught and mentored some one hundred young women who went on to careers in astronomy, mathematics, and the sciences. She was the oldest active woman astronomer and perhaps the oldest active astronomer.

Sadly, on April 9, 2007, Dr. Hoffleit passed away in her home after a brief illness. She leaves a tremendous legacy of over seventy years of astronomical work and the fact that her work continues on in the hundreds of people she has mentored in astronomy and in life over the years.

Clementine has finally molted! We at the MMA have been awaiting this for quite some time so I decided to re-post an old blog about Clementine. Well, not quite. But, part of my job is to also take care of all of the MMA properties. So, I headed over to check on one and what cleaning supplies are needed for the summer and for our staff spring clean-up of the site. In one room, some of the animals from the Aquarium over-winter. One of those is “our” lobster, Clementine, so-called because she is orange in color. (Orange lobsters are five times rarer than blue lobsters and only one in ten million lobsters are orange.) She is fairly active and though the hope is that she “sleeps” a bit for the winter, she doesn’t seem to. So, enter curator into room who glances over and hopes the lobster does not “run” to the side of the tank asking to be fed. Yes, she really does that – she has gotten used to people. I always hate it because I feel guilty – I do not feed her because that falls to the Natural Science Department and I do not want to hurt her or her schedule in any way. In any case, “Whew!” She actually seemed quiet at the back of the tank. Maybe she was “sleeping.” I kept moving to the next room and glanced back. Low and behold, she was at the front of the tank waving her claws! Seriously? So I kept moving on – after telling her, “I can’t feed you,” – and she went to the back of the tank again! Another, “Whew!” I decided to text Emily, our Director of Natural Science (at that time), and relay what happened. I get a text back. “You can feed her if you want.” “Really?” I texted back. “What do I give her?” So, Clementine then ran back to the front of the tank when she saw me opening the freezer and taking out the mussels and a shrimp. I got another text from Emily: “Use the forceps to hand them to her.” Well, I wasn’t about to put my hand in there! So, I get the shrimp, put it in the forceps, open the top of the tank and start to put my hand down, and INSTANTLY two HUGE lobster claws come out of the tank and grab not the shrimp but the forceps! I wish I had a picture. I was afraid she was going to take the forceps. And then, I was afraid my hand was going to be her lunch. I could not get her to release the forceps – it was a battle royale though the battle was more on her part because I was afraid I would break her claw! After some twisting of the forceps and tugging, she finally relented, took the shrimp, and began her lunch. Another, “Whew!” I was afraid I was either going to hurt her or I was going to be explaining to my three-year old what happened to Mommy’s hand at work. Veuve Clicquot with that, Clementine? Apparently, someone else knew what transpired with the lobster. As I left the building, a male mallard duck was paddling around in the rather large puddle – if you can call it that – located on the property. We have recently had a large amount of rain. He was laughing (I mean quacking) at me. In all seriousness, I have never met a lobster with so much personality. Yes, personality. Clementine may just have changed my tune on lobster rolls. JNLF

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
