Vestal Street Updates

Jascin N. Leonardo Finger • April 8, 2024

Vestal Street has seen a bevy of activity of late. In January, we began the renovation of the Maria Mitchell Vestal Street Observatory’s (MMO) Seminar Room addition – as it has been referred to since it was built in 1987. When it was created, the point was for it to serve as meeting, lecture, work space on three floors for the Astronomy Department – in particular the National Science Foundation Research Experiences for Undergraduate (NSF REU) interns we have each summer, visiting astronomers, and the astronomy staff.  Believe it or not, it was the first time the Observatory had a bathroom! And, it connected to what we refer to as the Astronomer’s Cottage (ca. 1830 and purchased for the MMA in 1922) so that staff could move between the house and the Observatory without going outside – convenient!  


With a gift from board member and Mitchell family descendant, Richard Wolfe, we have been able to renovate this space, bringing it up to date and adding HVAC, an accessible bathroom and kitchenette, three office spaces, a seminar/meeting area, and space for intern workspaces. Lighting and interiors are being improved as this is written and we hope to have the space ready by June 1, 2024. A special thank you goes to John Wise, another Board member, who has been working with the MMA to make sure this renovation happens in a short timeframe.


The work here dovetails nicely with the conservation of the historic observatory to which the Seminar Room is connected. The historic MMO, built in 1908 with a 1922 addition, has seen exterior conservation work over the last several years with support from the Community Preservation Act and the M. S. Worthington Foundation. This fall, we will move inside with more grant funding which will allow us to conserve the historic interiors and install a proper HVAC system to protect the historic fabric and historic astronomical equipment and papers. We will restore the floor in the Astronomical Study from 1922 – it’s hidden under wall-to-wall carpet and 1950s tile but it’s still there – and allow us to conserved the historic plaster and all of the original varnished woodwork. Stay tuned on

this project.

E. Dorrit Hoffleit, Ph.D.

By Jascin N. Leonardo Finger • September 8, 2025
Dorrit Hoffleit began her tenure at the MMO in 1957. A graduate of Radcliffe, Hoffleit earned a Ph.D. from Radcliffe in 1938. During World War Two, she worked for the U. S. government on missile trajectories and joined Yale’s Astronomy Department in 1956. Her directorship of the MMO allowed her to work part of the year on island and the remainder at Yale with the two organizations sharing her salary. She was the principal author of the Yale Bright Star Catalog – work that was continually added to over fifty years – and her work also focused on the study of variable stars. Hoffleit continued in the path of Harwood with research and public outreach, and bringing worldwide recognition to the MMO. Among her many accomplishments on behalf of the MMO, Hoffleit is known for her work with the National Science Foundation (NSF) and a grant she received in 1957 to allow for the summer training of female undergraduate students in astronomy. This was the pilot project for the national program of the Research Experiences for Undergraduates (REU) in various branches of science and technology, launched by the NSF in 1990. The MMA became a permanent REU site in astronomy, which is funded by the NSF based on periodically submitted proposals. Today, the MMO continues to have a lasting effect on its students. More than five percent of all the U.S. women becoming Ph.D.s in astronomy have participated in the MMA REU program. The probability of a current MMA REU student (either female or male) to become a Ph.D. is approximately sixty percent. Approximately fifty current professors of astronomy in the U. S. have participated in the REU program at the MMA. Hoffleit who retired from the MMO in 1978, continued her connections to the MMA up until the last weeks of her life. She passed away in 2007 at the age of one hundred. JNLF

Astronomical Study

By Jascin N. Leonardo Finger • August 25, 2025
With Margaret Harwood’s growing collection of glass plates of the night skies needing better storage and Harwood in need of a warm place to work in the fall and spring, the Hinchman family gave $5,000.00 towards the construction of a study and storage area at the MMO. The MMA was able to raise the remaining $1,500.00 needed and the Astronomical Study was built in 1922 between the Observatory and Mitchell House. The Astronomical Study was built as a memorial to Eliza R. Mitchell, the Treasurer of the MMA from 1905 to 1918, and a family member. JNLF

Maria Mitchell In Her Own Words

By Jascin N. Leonardo Finger • August 18, 2025
August 17{1857} Today we have been to the far-famed British museum. I carried as “open sesame” a paper given to me by Prof. Henry asking for me special attention from all societies with which the Smithsonian {is} connected . . . . The art of printing has brought us incalculable blessings, but as I looked at a neat manuscript book by Queen Elizabeth copied from another, as a present to her Father I could not help thinking that it was better than worsted work! On August 2, 1857, Maria Mitchell and the young woman she was accompanying as a chaperone, Prudence Smith, arrived in Liverpool England for their European tour. Maria Mitchell’s “open sesame” was a letter of introduction – she went with several. She would find that the doors were thrown open for America’s first woman astronomer – she was that well known in America and abroad. She would become quite close to Sir George Airy, the British Astronomer Royal, and his wife Richarda, as well as the astronomical Herschel family. JNLF
