The Lichen Guy

I did not know him well but I did know him for a long time.  He first comes into my memory when I was a young teenager at the MMA.  He was some sort of scientist associated with Nantucket’s UMASS Field Station.  He had an English accent.  He was funny and gregarious.  He was about quite a bit because of the work he was doing with students in the summer at the Field Station and because he was friendly and worked in conjunction with people who either worked for the MMA or had close ties to the MMA for a myriad of reasons.


I got to know him a bit better – as an adult – when I hosted a stone conservation workshop probably a dozen or so years ago.  It was the first time I did it.  I had written part of a grant to the Community Preservation Act to fund a workshop with a stone and paint conservator who I had been working with at the Mitchell House.  We had a dozen people show up – including the Prospect Hill Cemetery Historian who I now continue to do this workshop with – and Doug Eveleigh came too.  He came a little late and I was sort of surprised.  I knew a bit about what he did – and I am WAY oversimplifying it here – he studied fungi, moss, and lichens and had been using the stone monuments on Nantucket for some of his work.  Stone monument is another word for gravestone.  And, given the climate here –damp, fog, pure and reflective sun, few trees – the moss and lichens that grow on the stones is very unusual.  For a scientist working in such an area, a boon likely.  For the stones and a preservationist like me, a nightmare of destruction.


So, we taught people how to properly remove the lichen and moss without harming the historic stone monument.  And Professor Eveleigh sighed and sat and then began to regale us with all the amazingly different types of lichens and moss that we were in fact killing.  I offered him some gloves, a brush, some of the cleaner but he politely refused and said he would watch.  We learned a lot from him – it was an added bonus – and while I felt good about helping the stones I started to feel guiltier about killing the lichen and moss (still do to this day) and its little ecosystem.


In the end, with maybe ten minutes to go out of a two-hour program, he actually decided to remove some lichen and moss.  I was surprised – we all were – not sure what changed his mind.  But, ever since that day, I often remark about him joining us and his struggle to remove the moss and lichen when I lead such a workshop.  But, I also note how much he shared with us.  I know it was just scratching the surface (pun intended).


Over the years, I would occasionally hear from him or see him if he was back on island.  Always jovial and always mentioning the moss and lichen.


Sadly, Professor Eveleigh passed away at the end of December.  But, I will always remember his attendance at the stone workshop – and continue to tell the story.  I encourage you to look him  up – my blog here doesn’t do his life’s work justice.  I am, after all, a historian and preservationist not a scientist – though working for a science organization, I do try!

Well, actually replace the roof! With funding from the Community Preservation Act and the work of Lydon and Sons, Inc. the Mitchell House is getting a new roof. The current one had come to the end of its useful life. A cedar roof can last a long time – longer than asphalt – and is more historically accurate. The roof we are removing was installed in about 1992 – replacing a roof from the 1930s that was not cedar but a combination of materials that actually yes, did last sixty years. The unfortunate issue has arisen that the roofwalk (walk) has to be replaced. This is NOT the original walk – nor that old of a walk. It’s likely from the 1970s or so and has been cobbled at over time. It’s not a functioning walk – no one is allowed on it – but the Mitchell House needs it none the less. Maria Mitchell and her father, William, likely used the walk for astronomical observations – in addition to the yard – but the walk is also protected as part of the preservation easement on the House. Walks – NOT and NEVER called widow’s walks – were used for preventing and putting out chimney fire and roof fires. In a place where wood was expensive and had to be brought from “the main” these were purely utilitarian. What good Quaker (or non-Quaker) would build a platform for his wife to stare out to the harbor to see if her husband was on his way home? The other issue is that the walk was completely resting on the ridge board – and actually was notched to accept the pitch and tip of the ridge board so they couldn’t work around it. I suspect this may have been the ways walks were once built – and also a crafty and smart thinking carpenter who came up with the idea. It makes the walk lower. But between that issue and the age of the walk and then the blizzard of February 2026 that packed gusts over 83 MPH (that’s Category 1 hurricane winds) the walk gave in. Balusters had been knocked out and the railings were loose and pulling away from the posts. So, we will also be working with Barber and Sons to create a new roofwalk – and they agreed to do this for us quickly which is also no small feat given how busy everyone is these days. So from the bottom of the Mitchell House’s heart (and mine) a big thank you to Chris Lydon and Lydon and Sons and crew, Barber and Sons / Beau and Nate Barber, the Community Preservation Committee, and Nantucket Preservation Trust (our easement holder)!

NANTUCKET, MA—The Maria Mitchell Association (MMA) invites the community to “Dark and Quiet: Astronomy in the Age of Satellite Constellation” presented by Dr. Joshua Reding for its April Science Speaker Series. This free presentation will take place Wednesday, April 15 from 7 – 8pm on Zoom. In the past decade, the number of active satellites in Earth’s orbit has grown by a factor of 10. This breakneck growth in the commercial space industry has turned entrepreneur, investor, and policymaker eyes to the skies, but in the process has boxed out the historic stewards of the space domain: scientists. Explorers and pioneers across human history learned that uncharted territory hides unprecedented challenges, but the consequences of decisions made towards occupying the “final frontier” do not abide by international borders. Space operators therefore ignore the warnings and concerns of scientists not only at their own risk, but at the risk of everyone living under increasingly crowded skies. In this conversation, Dr. Josh Reding will explain how astronomers are trying to inform and guide policymaking for the rapidly changing space environment, both informally through volunteer action and advocacy and formally in domestic and international policy forums. Dr. Reding is an optical astronomer by training and now a radio spectrum manager by profession. He completed his B.A. with a double major in Astronomy-Physics and Philosophy at Colgate University, and his M.S. and Ph.D. in Physics from the University of North Carolina at Chapel Hill. His research investigated unusual white dwarf stars that likely formed in stellar mergers as “failed” supernovae and he has also designed astronomical instrument components and installed them at world-class observatories. Concurrent with the completion of his Ph.D., Reding began his professional science policy career as a North Carolina STEM Policy Fellow in the NC Department of Commerce’s Office of Science, Technology & Innovation. He was then selected for the American Association for the Advancement of Science Science & Technology Policy Fellowship, which places scientists in federal offices as expert contributors to ongoing agency missions. This event will be held via Zoom. Pre-registration is required. To register for the free, virtual event, use the registration link: https://us06web.zoom.us/webinar/register/WN_5MoAybp5QHCasQ0QE5xmgQ#/registration The Science Speaker Series is generously sponsored by the Maria Mitchell Association’s lead sponsor, Bank of America. The Maria Mitchell Association was founded in 1902 to preserve the legacy of Nantucket native astronomer, naturalist, librarian, and educator, Maria Mitchell. After she discovered a comet in 1847, Mitchell’s international fame led to many achievements and awards, including an appointment as the first professor of astronomy at Vassar College. Maria Mitchell believed in “learning by doing” and today that philosophy is reflected in the MMA’s mission statement, programs, research projects, and other activities. The Maria Mitchell Association operates two observatories, a natural science museum, an aquarium, a research center, and preserves the historic birthplace of Maria Mitchell. A wide variety of science and history-related programming is offered throughout the year for people of all ages. ###
