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

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!
