What Mattatuck Historical Society does
Mission
The mattatuck museum is a center of art and history, a gathering place that nurtures creativity and learning through transformative experiences to encourage a deeper understanding of ourselves and our heritage.
As stated on its FY2025 Form 990.
Programs
The mattatuck museum focuses on education as a central mission component, fostering relationships within the community. These learning and outreach efforts establish the museum as a key resource for interacting with art and history. In the last fiscal year, the museum prioritized creating varied public and school programs to strengthen this bond, offering chances for engagement throughout life, from early childhood to retirement. The museum serves diverse groups, including young children, families, k-12 students, adolescents, and adults, through different programming. While centered on residents of the greater waterbury region, the goal is to reach audiences across western connecticut. The mattatuck aims to offer an environment that is safe, accessible, and welcoming for families seeking enriching group experiences. The museum's programs hold significant value as many children and family units rarely access the fine arts due to historic issues with accessiblilty. Program offerings include virtual and on-site visits for k-12 classrooms, specific school's out activities during breaks, dedicated art and history programs for homeschool communities, independent gallery visits,…
It is my great pleasure to highlight the achievements of the mattatuck museum curatorial department this past year. Things continue to be busy as we present strong exhibitions, develop our collections in accordance with our collecting plan, and engage with the community. The mattatuck continues to present a robust and engaging exhibition schedule that tells important stories while reflecting the diversity of our community. We mounted 11 unique exhibitions in our changing galleries this fiscal year. Half of these shows were internally organized, which allows us to tailor them to present local artists, engage with relevant topics, and respond to the community. The remainder were loan shows organized with the assistance of art bridges foundation and brought artists of international renown to the mattatuck walls. On exhibit curated internally but featuring works on loan through the art bridges partner loan network, modern women: georgia o'keeffe & kay sage, received a connecticut league of museums 2025 award of merit. In addition to the large-scale exhibitions we organize for changing gallery spaces, this past year the department presented three smaller installations in the history…
The museum also provides a range of programs and tours specific to adult audiences. These include lectures, creative arts workshops, social painting sessions, stage performances, and music events. These are complemented by a mobile outreach effort, matt on the go, delivered virtually and in person. The museum supports wellbeing with weekly classes in yoga, tai chi, and mindfulness. In partnership with the alzheimer's association of connecticut, the memories @ the matt initiative offers specialized virtual gallery experiences for individuals in the early stages of dementia or alzheimer's and their caregivers.
Library & archives october 2024-september 2025: the museum's archivist focused on increasing access to the archival and library collections by publishing new finding aids to connecticut archives online. The archivist made oral histories available on the public portal and created workflows to upload digitized archival items to the connecticut digital archives (ctda). There were several donations of art and history books to the museum's library. Work continued to update the library's online catalogue, and there are more than 2,500 books from the collection searchable through tinycat and the museum's website. The library and archive is used by both amateur enthusiasts and scholars alike in areas of historical research, art history investigation and genealogy. Last year, the museum assisted with approximately 110 regional and national independent research requests through phone, email, and in- person research appointments. The number of in-person research appointments increased from 12 the previous year to 28 this year. Within the museum, the archivist provided images for social media and other department requests totaling 20 separate collaborations. The museum's archivist accepted a…

The 4 programs described on its FY2024 Form 990, listed largest first by expense. Program spending in total: $2,673,033.
The organization over time
Each line starts at 100 in 2017, so what you read is the shape rather than the size: 150 means half as much again as 2017, 50 means half. The number beside each label in the key is where it ended. The shaded band is where the middle 50% of its peers' revenue would sit, given their growth.
Balance sheet
Total assets and total liabilities at each year end, in dollars. The largest one-year move in total assets was 2019 to 2020, from $26M to $31M (+17%).
How it's funded, over time
Each bar is one year's revenue split into where it came from, and every bar is the same height — these are shares, not amounts, so a year that raised twice as much looks the same size. Hover a bar for the split.
Government-grant reliance: 2017 4% · 2018 2% · 2019 20% · 2020 55% · 2021 19% · 2022 9% · 2024 1% · 2025 3%. Grants only. Government contracts and fees sit inside program revenue.
37% of MATTATUCK HISTORICAL SOCIETY’s revenue is contributions — about as donation-reliant as the typical peer (63% for the typical peer).
Surplus & reserves
Operating surplus or deficit each year, and months of liquidity in hand. 1 of the last 8 reported years ran a deficit.

Leadership and staff
The officers, directors, trustees and key employees listed on each return. Joined and no longer listed compare each filing with the year before, matching people by surname and first initial; a year after a gap, or a roster under three people, has no comparison.
Who funds it, year by year
2017 → 2023: the base broadened from 6 funders to 13 funders, grant income rose $128k → $179k.
5 of 37 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 34% of grant dollars received. That money is really individual donors directing a sponsor; the institutions to cultivate are the non-DAF funders.
Left out of every figure on this page: $19k from one payer (the payer shares this organization's board, largest The United Way of Greater Waterbury Inc). These are real filings, and they are not money MATTATUCK HISTORICAL SOCIETY raised.
From the IRS filings of MATTATUCK HISTORICAL SOCIETY’s funders (the co-funder graph). Top 30 of 37 funders by total. Association, not causation. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
How concentrated its funding is
MATTATUCK HISTORICAL SOCIETY has a broad base — no single funder exceeds 29% of grant income, and it takes 3 funders to reach half.
the vertical line marks half of all grant income — 3 funders to its left
54% of the income these shares are computed over arrives through pass-through sponsors or from payers whose filings do not say what kind of payment it is. Concentration is still measured over all of it, because the money is real; what it does not support is a claim about how many institutions have chosen to fund MATTATUCK HISTORICAL SOCIETY.
Largest funder’s share by year: 2017 71% · 2018 57% · 2019 30% · 2020 23% · 2021 43% · 2022 40% · 2023 29% — diversifying over time.
“Effective funders” = inverse Herfindahl index (1 / Σ shareᵢ²) — the number of equal-sized funders that would give the same concentration. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
How long its funders stay
58% of MATTATUCK HISTORICAL SOCIETY's funders are still giving 3 years after their first grant; 57% give in more than one year at all.
Share of funders still giving k years after their first recorded grant, pooled across every acquisition cohort. A funder counts as retained in a year only if it made a grant that year. Measured to FY2023, the last fiscal year that has finished arriving — a funder cannot be counted as lapsed in a year most filers have not reached.
Where its funders are
73% of MATTATUCK HISTORICAL SOCIETY's grant income comes from Connecticut funders.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $726k arriving through sponsors registered in 5 states is excluded from the map and the split above: a sponsor holds money on a donor’s behalf, so its registered address would place those dollars somewhere no donor need ever have been. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
Against its field
MATTATUCK HISTORICAL SOCIETY's funding base is broadening — from 6 funders to 13 as grant income climbed.
