The Second Director of the Maria Mitchell Observatory

Jascin N. Leonardo Finger • March 31, 2021

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.

A repost from long ago – because I still like a good chair. Quite awhile ago, I wrote about some of my collection addictions, including pottery shards, 19 th century kitchen mirrors, and of course, enamelware. Well, here is another one for you. I love chairs. Yes, this is another collection addiction of mine. But not all chairs – chairs from the eighteenth and nineteenth centuries. Typically, I like plain, simple wood chairs with a horizontal piece or two of wood for the back and a plain, thick wood seat. Simple, not a lot of turns to the wood, and not a lot of decorative features or paint. Several years ago, I had a meeting at the home of the leader of a group I was working with. She owned the Obed Macy house, very much untouched and quite a remarkable house. Yes, Obed was the Nantucket historian (among other things), as well as the son of island entrepreneur Judith Macy, and the nephew of the island “she-pirate” Kezia Coffin. We met outside on the side porch which was a late 19 th century addition to the house and one that certainly reflected what life was like in the period it was added to the house. The owner had brought out every chair in her home. I was on a chair high (not a highchair!) – here I had my choice of nineteenth chairs to sit on. Since I was one of the first to arrive, I took my time picking out which chair I was going to sit on – I kid you not. I was like Goldilocks − though I was grown-up enough not to sit on every chair to decide which one I was going to claim for the meeting! I went on and on and likely on and on about all these lovely chairs to her. Unfortunately, the day came several years later when she was faced with having to sell her beloved home to move off-island. She called me. She wanted to know if I wanted any of her chairs since she remembered how much I went on and on about them. It was a mixture of emotion because losing this island resident was a loss for the island and for its history and historic architecture. I went to her home a few days before she was going to have her sale and helped her move items from the house out onto the lovely 19 th century side porch where I first reveled in her chair collection and also out into the large, simple backyard that looked like it too had not been touched since the 19 th century. She told me to take whichever chairs I wanted as she wanted me to have them. Depressing. I told her I would not take but that I would buy. We had a little back and forth but she finally relented. Then, I had to choose and it was quite agonizing. Not wanting to be a chair hog, I limited myself. I now have two matching and two others sitting around my dining room table made from salvaged Nantucket pine floorboards. We refer to them as “Helen’s chairs” – their previous owner. She likely found them here on Nantucket; one or more may have even come with the house when she bought it. We eat every meal sitting in them, spend time with our family in long discussions and laughter sitting in them, and each time I sit, touch, dust, or move them, I think of Helen and the house these chairs once sat in and the conversations and people they must have witnessed over the many years. A simple wood chair – a witness to history and time. JNLF

A repost – with my apologies – from last year. It started budding the week of April 30 this year. This is what our landscaper for the MMA calls it. “The ancient vine.” He tells the people who work for him not to touch the “ancient vine.” I have probably made him – and all of them – terrified of it. I am even terrified of it to some degree. I refer to the grape vine behind the Mitchell House that is supposed to be Peleg Mitchell Junior’s grape vine – Maria Mitchell’s uncle who inhabited the house from about 1836 to his death in 1882. It has two trunks but one died several years ago. Because of that, each year I try to root shoots. It’s fairly easy to do – when you cut back the vine in late fall/early winter. I have had success but not success protecting the shoots I baby all winter from bunnies and other critters once I plant them – try as I might. I started doing this when the one trunk died – I was PANICKED! The landscaper stays away because I have told him if anyone is going to accidentally harm or worse yet, kill, this grape vine it would be me so I only have myself to blame. So each November/December – once ALL the leaves have fallen off – I climb my ladder and quietly, carefully, and fearfully cut back the stems typically to two buds. I have been somewhat successful in spurring grape production – and these grapes attract some amazing birds in the fall. It takes me some time – and I pretty much hyperventilate the entire time – and then, I stare at it all winter. Passing under it multiple times a day to reach my office. Hoping, and yes, praying, it will come out in the spring. It’s a late budder so just recently the buds started to show themselves – thank goodness! – and I was rewarded today (May 5, 2025) with this wonderful hot pink color on the edges of the leaves as they are uncurling.

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
