Looking East

Jascin N. Leonardo Finger • February 7, 2022

Or west, if you are considering it’s the west side of the Mitchell House. In the setting sun the week of January 24. I love how the sun has such a warm glow on the House. For the most part, that would be the same setting sun that Maria saw on the side of the House ̶ save for the telephone pole – you can make out its shape there. Sort of right in the middle and running up into the attic window.


You can also see some of the “debris” from work we are doing. First – the Mitchell House chimney is being reparged on the rear. Pen Austin, an island mason who specializes in historic masonry, plaster and paint treatments is conducting that work which was grant funded. She has given this chimney some TLC over the years and is now adding layer upon layer of lime mortar to the chimney. While this is not historically accurate (by 1790s standards when the House was built), it was done to the chimney starting in the late nineteenth century and thus it stays that way – and helps protect it at this point. The chimney was rebuilt at some point – probably in the later part of the nineteenth century – but below the roofline it is completely the 1790 chimney. Believe it or not, that’s not a common thing as when chimneys were rebuilt, a lot of the time they would be rebuilt in the attic spaces (below the roof/ridgeline), too.


The second area is the wood in the yard and the staging. This is for the mason, Wayne Morris, who is working on the conservation of the Maria Mitchell Vestal Street    Observatory – also grant funded and this time via a Community Preservation Act grant. He’s completed some work where you see the support on the roof and if it was a better, closer photograph, you could make out the area of the last “parapet” closest to the Mitchell House where he has done some investigating. He will need to re-build those.  He has been investigating how the slabs was installed so that he knows how to pull them (they are made of concrete) without damaging them. On that particular one, he found a wood shim. Not unusual, but it was completely rotted and crumbled because it had gotten wet over the last 100 years as water found its way in. That shim will be going away and if something is needed, a steel piece will go in – it doesn’t rot and it doesn’t rust! And it’s the acceptable thing to do in such conservation work here.

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

Maria Mitchell Vestal Street Observatory: Conserved, Refreshed, and Renewed

By Jascin N. Leonardo Finger • August 11, 2025
After many years on the making, we are happy to officially announce the re-opening of the Maria Mitchell Vestal Street Observatory – also fondly referred to as the MMO. As you may have seen on the Maria Mitchell’s Attic bog, this has truly been more than a multi-year labor of love. Way back in 2016, we began the first steps with a structural assessment by structural engineer, John Wathne of Structures-North. That, coupled with an earlier Conservation Assessment Program grant from Heritage Preservation and supported by the Institute for Museum and Library Services that allowed the MMA to hire architectural conservator, Michael Devonshire, began us on our path to conserve the historic MMO. Grants from the Community Preservation Act and the M. S. Worthington Foundation supported the conservation work on the 1908 Observatory and its 1922 Astronomical Study. Masonry and grout were repaired, rusted iron lintels over windows and doors were replaced with steel and work was completed to the “parapets.” This sounds simple – it was not – it was a multi- year project to work with the masonry and to create a matching grout. Wayne Morris, the mason, became a fixture on Vestal Street again – as he did all the masonry conservation and work on the exterior of the Research Center. Once the MMO’s exterior was weather tight and the interior masonry work completed, the rest of the crew moved in to conserve the plaster, re-paint, and conserve the original 1922 bookcases and woodwork in the Study. Paint was removed from the dome bringing it back to its original glory. Cement floors were cleaned and treated and electrical wiring was updated and new lighting put in the Study. A major renovation was also conducted concerning the “Seminar Room” – a 1987 addition to the west of the MMO – which was completed in 2024. This was funded in large part by Mitchell family descendant and former (now honorary) MMA Board Member, Richard Wolfe. New office spaces were created for astronomy staff, updates were made to the astronomy intern workspace and meeting space, and a new accessible bathroom was completed. We also owe a huge debt of gratitude to two other board members in this work, particularly with the Seminar Room – Elizabeth Markel and John Wise. We would like to thank everyone for their roles in making this long journey a success and for doing all of this important work. Thank you does not express it well enough – they have truly all been heroes of the MMO. We are beyond grateful. THANK YOU and WOW it all looks incredible!

Glass Plate Photographic Collection

By Jascin N. Leonardo Finger • August 4, 2025
With the help of Edward Pickering from Harvard, the MMA was able to develop a research program and realized that a photographic telescope would be necessary. Funds were raised and by November 1913, a 7.5-inch photographic telescope was installed. Using Maria Mitchell’s 5-inch Alvan Clark telescope as a guide for the larger photographic telescope, the photographic telescope had a lens from Thomas Cooke and Sons of York, England and a cast-iron pier, mount, and clockwork by Alvan Clark & Sons in Cambridge, MA. The pier, mount, and clockwork are still present in the MMO – the pier and mount still utilized but by a 17-inch research telescope purchased with a grant from the National Science Foundation. The glass plates taken of the night sky at the MMO total more than 8,000 and they are still utilized for research. They capture a moment in the night sky that can never be captured again – just like a regular photograph. In order to capture the image of the night sky, exposures could last for as long as three hours or more. Glass plates were heavily used for researching variable stars. They also afforded opportunities for new discoveries that could go unnoticed when one looked through a telescope by eye. Glass plates are gelatin-coated dry plate negatives that first came into use in the 1870s. They were utilized well into the late twentieth century particularly because they did not shrink or deform like plastic film. At the MMA, we continued to take glass plates of the night sky until 1995 when we had the opportunity and funding to update to a CCD camera – charge-coupled devices. While the CCDs provided many improvements, they still did not have the detecting area and resolution of glass plates. Technology continues to evolve, and the MMA with it, as we work with new methods to capture the night sky photographically. JNLF
