Kelly Bernatzky • July 28, 2021

Helene Weld, the President of the Board of Directors of the Nantucket Maria Mitchell Association (MMA), announced today that Joanna Roche will take on the role of MMA’s next Executive Director. According to Weld, “While our search allowed us to consider a number of excellent candidates from across the country, we are pleased to welcome a Nantucket resident to this critical role. We are certain Joanna is the person to take our organization to the next level in achieving our mission: to create opportunities for all to develop a life-long passion for science through education, research, and first-hand exploration of the sky, land, and sea of Nantucket Island.”

 

Joanna is a proven leader who has extensive experience in both the nonprofit and business world. In her past roles, she has led large teams, worked successfully with diverse boards, delivered strong financial performance, increased and strengthened revenue streams, and focused on providing exceptional guest experiences. Her past career successes will serve her well in carrying out the goals of the MMA.

 

Joanna has articulated a bold vision for the future and for what can be next for the organization, including raising the visibility of MMA not only on the island but nationally; enhancing the overall experience for those visiting and interacting with MMA; and building and diversifying the funding streams for the organization.

 

Joanna said, “I’m especially enthusiastic about using my passion to help continue to promote the legacy of Maria Mitchell. Mitchell was a true pioneer, not only as a woman scientist, but as a woman leader who was far ahead of her time in advocating for and supporting the next generation of the curious, and those who love nature and learning.”

 

She has a well-established network of connections on the island and has served on the Town of Nantucket Finance Committee for the past six years. She was also recently named to the Coastal Resiliency Advisory Committee, where she will advocate for and contribute her expertise on issues of importance to both the island and the MMA.

 

She was most recently the Executive Director of GSN Planet and Foundation, where she led two global nonprofits focused on sustainability and education in the wellness arena. She has consulted on numerous new capital and development projects, managing budgets, financial oversight, and revenue growth. She also served as an executive at the Westmoor Club where she led the vision, revenue growth, and staff of the Club’s Wellness Center. Earlier in her career, she was Executive Vice President and Chief Creative Strategist for Pierce Mattie Public Relations in New York.

 

Frances Symes, who serves on the MMA Board and co-chaired the search committee, said, “MMA is pleased and excited to have the talents and energy of Joanna as our new leader. With her understanding of the island combined with her passion for the environment, business expertise and commitment to a high-quality visitor experience, we know MMA’s future is in good hands.”

 

Originally from the Berkshires, in western Massachusetts, Joanna has always been active in the communities where she has lived, serving on many local boards and committees. She is also a well-known speaker, hosted a long-running radio show here on Nantucket, and is a wellness and meditation teacher. Roche loves the outdoors, and is a longtime runner. 

 

Weld concludes, “This is an exciting time for MMA, as we look to the future and find new ways to grow our impact and presence both here on Nantucket and nationally. Having Joanna as Executive Director will make us that much more successful in leading the organization into a strong and vibrant future. We are grateful to Interim Director Jason Bridges for skillfully leading the Maria Mitchell Association over the past year.”

 

The Maria Mitchell Association is a private non-profit organization. Founded in 1902, the MMA works to preserve the legacy of Nantucket native astronomer, naturalist, librarian, and educator, Maria Mitchell. 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.

The Ice Man Cometh

By Jascin N. Leonardo Finger • August 10, 2026
This is a blog of the past. I often think of this “story” when it’s hot and humid out. So here it is again. The past few weeks have been very un-Nantucket as far as the heat and the extreme humidity. When I was a child and even a teenager, I remember that we always wore long pants and even sweaters in the summer evenings on island. This does not seem to be the norm any longer unfortunately. The heat also leads me to think about staying cool and what generations before us did to preserve food. Long before modern refrigeration, ice was used for preserving foods. Although the use of ice brought an end to salting and drying fish for local markets, with railroad development and western expansion in the 1850s, salt fish was still being shipped to inland domestic markets as well as abroad. As the fishing industry grew on Nantucket and elsewhere, however, so did the need for ice to keep the catch fresh for market. On Nantucket, when a hard freeze produced ice of the necessary thickness, blocks were cut from Maxcey’s and Washing Ponds and the North Head of Hummock Pond and stored in nearby icehouses. This was a fairly long and tricky process that took skill to make sure the ice was the right thickness and that one did not fall through the ice. Mainland icehouses typically used sawdust for insulation, but Nantucket ice was insulated with beach grass, seaweed, and eelgrass—sawdust not being readily available here. The iceman would drive his cart around the streets with usually a gaggle of children trailing behind – or hitching a secretive ride on the back of the cart – hoping for a piece of ice to suck on and cool off with – back when something that simple was a pure delicacy. When electricity was introduced on Nantucket in 1889, cutting pond ice was no longer necessary. Captain John “Jack” Killen built the first ice-making plant, on Straight Wharf, opening it on May 5, 1902. Several other plants, including that of the Island Service Company, followed—all operating until the Great Depression. Nantucket’s early ice-making plants were established primarily for packing fish and shellfish, which were shipped in barrels or fish boxes layered with ice. Fishermen both on and off-island would stock up on ice before going out on long trips, and it is said that island ice was of a much higher quality than that from plants off-island—perhaps because of the purity of Nantucket’s water. Some people still cut ice. My parents had an elderly friend, now gone, and his family owned – and I assume still owns – a camp of cottages from the 19 th century up in New Hampshire. In the winter, the entire family shows up to harvest ice and store it in the icehouse. The ice is then used in each of the cottages during the summer since they have no electricity or plumbing. It is an art that is almost gone but happily there are still a few who have passed down the knowledge and skill for harvesting ice. I recently took a look at his obituary and was blown away – I remember him for ice harvesting – but wow what a life! One of service and seeking justice. JNLF

Through conservation, research, education, and advocacy, the organization works to preserve open spaces, protect water quality, and ensure the long-term environmental health of Nantucket for future generations. 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. ####
