Maclean Foundation is a private corporation based in MUNDELEIN, IL. The foundation received its IRS ruling in 1996. The principal officer is Thomas M Pruden. It holds total assets of $19.3M. Annual income is reported at $1M. Total assets have grown from $537K in 2011 to $22.4M in 2023. The foundation is governed by 4 officers and trustees. Tax records are available from 2015 to 2023. According to available records, Maclean Foundation has made 13 grants totaling $16.8M, with a median grant of $746K. Annual giving has decreased from $10.6M in 2022 to $6.3M in 2023. Individual grants have ranged from $60K to $6.6M, with an average award of $1.3M. The foundation has supported 11 unique organizations. The foundation primarily supports organizations in New Hampshire, Illinois, Connecticut, which account for 77% of all grants. Grantmaking reaches organizations across 6 states. Contributions to this foundation are tax-deductible.
The Maclean Foundation is a private grantmaking foundation wholly shaped by the personal philanthropic vision of Barry MacLean, Chairman of MacLean-Fogg Company, a Mundelein, Illinois-based manufacturing conglomerate. Unlike foundations with formal grant programs, published eligibility criteria, or open application portals, the Maclean Foundation functions as an extension of its founder's institutional relationships — directing capital toward organizations where MacLean has served as trustee, board member, or major benefactor over a multi-decade career.
The foundation's giving history reveals an unmistakable pattern: every major grant recipient corresponds directly to an institution where Barry MacLean holds or has held a formal leadership role. Dartmouth College and its Thayer School of Engineering — MacLean's alma mater and the institution where he served on the Board of Overseers for over 36 years — received $8.6M. The University of Chicago (where MacLean is a University Hospitals trustee and the MacLean Center for Clinical Medical Ethics bears the family name) received $3.5M. The Art Institute of Chicago and Millennium Park Foundation align with MacLean's former chairmanship of the School of the Art Institute and his role as Art Institute Vice Chairman. The Museum of Science and Industry, where MacLean has been a trustee, received $750K. Shirley Ryan Ability Lab is consistent with his University of Chicago Hospitals affiliation.
For first-time applicants, the critical insight is this: there is no competitive grant cycle and no RFP. No letters of inquiry are invited from unknown organizations. The foundation has no public-facing grantmaking website, no published application process, and its database record carries a preselected-only designation — confirming that grants flow exclusively to organizations already within the MacLean network.
The typical relationship progression, drawn from the pattern of giving, is: long-term institutional engagement with MacLean as a board member or trustee, followed by a capital request — a named building, endowed chair, or program expansion — that MacLean champions as a leadership or transformational gift. Organizations in Chicago's arts, education, science, and medical sectors, or those with a Dartmouth College connection, and that have an existing relationship with the MacLean family are the only realistic candidates for engagement. Cold outreach is unlikely to succeed.
The Maclean Foundation's financial trajectory divides into two distinct eras separated by a single transformational event. From 2011 through 2021, the foundation operated as a very small family philanthropic vehicle, with assets ranging from $537K to $644K and annual grants totaling $20K–$113K: $75K in 2011, $25K in 2012, $113K in 2013, $104K in 2014, $75K in 2015, $65K in 2019, and $20K in each of 2020 and 2021.
In fiscal year 2022, the foundation received a single contribution of $38 million — almost certainly an endowment transfer from Barry MacLean or MacLean-Fogg Company. This injection lifted assets to $27.5M and immediately triggered large-scale institutional grantmaking: $10.58M in FY2022, $6.26M in FY2023, and approximately $4.08M in FY2024.
Across 13 documented grants totaling $16.84M in the database, the average grant is $1.3M. The median sits near $746K–$750K (between the Museum of Science and Industry grant and Union College grant). The smallest documented grant is $60K (Lake Forest Country Day School) and the largest is $8.6M (Dartmouth College, two-tranche Thayer Expansion Commitment).
By program area: Higher Education captures the dominant share at approximately $12.84M (76%) — Dartmouth $8.6M, University of Chicago $3.5M, Union College $746K. K-12 Education represents ~$1.26M (7.5%) via Loomis Chaffee School ($1.2M) and Lake Forest Country Day School ($60K). Chicago arts and culture accounts for ~$1M (6%) — Art Institute $500K, Millennium Park Foundation $500K. Science education (Museum of Science and Industry) is $750K (4.5%). Health and rehabilitation (Shirley Ryan Ability Lab) is $675K (4%). Conservation and wildlife (African Wildlife Foundation $160K, Ruffed Grouse Society $100K) totals $260K (1.5%).
Geographically, Illinois receives approximately 57% of grant dollars through Chicago-area institutions. New Hampshire (Dartmouth) captures roughly 51% — the overlap is because Dartmouth's total exceeds individual Illinois grant totals. The foundation's spend-down trajectory suggests a 5-7 year active major-grantmaking window before assets limit future large commitments.
The Maclean Foundation's data-matched peer cohort consists of private family foundations of similar asset scale (~$19.3M), all classified under NTEE category T (Philanthropy & Grantmaking). None of the matched peers have publicly available grantmaking histories, reflecting the typical opacity of small family foundations.

What distinguishes the Maclean Foundation within this peer group is its exceptional giving velocity: in FY2022–2023 alone, it distributed over $16.8M — nearly its entire current asset base — while asset-matched peers show no comparable grantmaking activity in public records. This aggressive distribution pace, combined with a clear spend-down trajectory (assets fell from $27.5M in 2022 to $19.3M by 2024), indicates the foundation is operating more like a time-limited donor-advised vehicle than a perpetual endowment. Grant seekers should note that the active major-grantmaking window appears short — likely 3-7 years — before assets reach a level that constrains large capital commitments.
The Maclean Foundation's most significant documented activity is the Dartmouth College Thayer Expansion Commitment, recorded as $8.6M across two IRS-reported grants. This aligns with Barry MacLean's history as the largest single donor in Thayer School's 158-year history. A $25M gift announced in May 2016 included $15M for the MacLean Engineering Sciences Center and $10M as a challenge grant for endowed professorships — with portions flowing through the foundation over subsequent years.
In late 2025, Dartmouth Engineering published a profile honoring Barry MacLean '60 Th'61 for 50 years of service on the Thayer Board of Advisors, noting that Thayer grew from 65 engineering degrees annually (1976) to 384 by 2025. His family — three children and a granddaughter — are Dartmouth graduates.
The University of Chicago connection is anchored by the MacLean Center for Clinical Medical Ethics, established in 1983 with support from Dorothy J. MacLean and the MacLean family. Barry MacLean has served as trustee of University of Chicago Hospitals and as Vice Chairman and former chairman of the School of the Art Institute of Chicago.
No public grants announcements, press releases, or new program launches specific to the Maclean Foundation as a grantmaking entity were found for 2025 or 2026. The foundation does not maintain a grantmaking website or issue public communications. Its address (1000 Allanson Rd, Mundelein, IL 60060) is MacLean-Fogg Company's corporate headquarters, and the listed contact is Thomas M Pruden (847-566-0010), confirming the foundation operates as an administrative function within the family enterprise rather than as a standalone philanthropic institution.
Prospective grantees must approach the Maclean Foundation with clear-eyed realism: this is a relationship-driven foundation with no open application process, no published grant guidelines, and a preselected-only grantee designation. Every documented dollar in its grantmaking history has flowed to institutions where Barry MacLean has personal leadership involvement spanning decades.
Audit your network before anything else. Determine whether any member of your board, major donors, or senior leadership has a documented connection to Barry MacLean, Brooke MacLean (Vice President of the foundation), MacLean-Fogg Company, or any institution in the MacLean network: Dartmouth College, University of Chicago, Art Institute of Chicago, Museum of Science and Industry, Shirley Ryan Ability Lab, Millennium Park Foundation, African Wildlife Foundation, or Ruffed Grouse Society. A warm introduction from a mutual institutional connection is the minimum threshold for any engagement.
Frame exclusively around capital impact. Barry MacLean's entire philanthropic track record consists of named capital commitments: buildings, endowed professorships, program expansions, capacity-building campaigns. He is not a programmatic funder. Any viable request must be structured as a transformational or naming gift opportunity of at least $500K. Smaller asks ($60K–$160K) in the database reflect personal charitable interests (wildlife, local education) rather than institutional relationships — and those organizations likely had prior connections.
Use institutional channels, not cold outreach. The highest-probability pathway is engagement through trustee or development networks at Dartmouth or University of Chicago — institutions where MacLean is already deeply embedded. A Dartmouth development officer or University of Chicago Hospitals trustee can provide context on whether an introduction to MacLean is appropriate.
Contact Thomas M Pruden directly. As the listed foundation contact (847-566-0010, 1000 Allanson Rd, Mundelein, IL), Pruden is the operational point of contact. A brief, professional inquiry about whether the foundation accepts any solicited interest letters is a defensible first step — but expect the answer to be no unless you already have a relationship angle.
Plan for 12–36 month cultivation. Based on the foundation's giving history, relationships precede grants by years, not months. The Dartmouth and University of Chicago commitments reflect decades of personal engagement. Do not approach this foundation as a one-cycle prospect.
