A Patchwork of Tiles

Jascin N. Leonardo Finger • September 8, 2015

What you are looking at is the interior south wall of the MMA Library/EcologyLab. I believe at some time in my blogging about the MMA Library conservation work, I mentioned that the terracotta tiles and the exterior stucco and the interior walls of the building were pretty much all one piece sp to speak. These photographs certainly illustrate that. Those ridges you see are actually the terracotta tiles which make up the structural walls of the building. When built in the early 1930s, about three coats of a lime plaster were placed on the terracotta and then tempera paint which is the more yellow looking finish you see in areas where the plaster did not fail. If not for some leaks about a decade or more ago, the plaster would not have failed because everywhere else in the Wing the plaster is in excellent condition – you can’t beat lime plaster!

But due to the damage from the leaks, the lime plaster had blistered and pulled from the terracotta so in we called Pen Austin (I have blogged about her before), an island mason who specializes in traditional methods of mortar, paint finishes, and plaster. Her work is partially Community Preservation Act funded – it became a bigger project because of the work that was completed on the outside of the building – remember again that this is all like one piece. We have the right woman – and her team – on the job and she hopes to be completed with the plaster work in about a week. It will take about a month for the lime plaster to cure and then painters can paint the walls.

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
