Eucalyptus Foundation

The Eucalyptus Foundation is a tightly held Geballe family foundation that operates with deliberate informality and minimal public profile. Founded in 1992, it traces its leadership to the Koshland family — descendants of the founders of Levi Strauss & Co. — and has grown from $29 million in assets in 2016 to $265 million in FY2024, making it a substantial mid-tier Bay Area funder despite near-total invisibility in the philanthropic press.

The giving philosophy is deeply personal and relationship-driven. There is no published grant program, no application portal, and no review calendar. The foundation does not accept unsolicited applications — a consistent statement across every available database — and selects all grantees proactively. This is not a formal invitation-only program in the Hewlett or Packard sense; rather, it reflects a family foundation culture where board members personally know their grantees and grants arise from trusted relationships, not competitive review.

The intellectual fingerprint of founding president Theodore H. Geballe — a legendary condensed matter physicist who worked at Bell Labs and Stanford for six decades before his death on October 23, 2021 — is visible across the portfolio. Science education grants (Eastside College Preparatory's High School Physics Program: $441,000 cumulative; American Physical Society's PhysicsQuest program: $200,000) and support for research-adjacent institutions reflect a deep belief in science as a public good. Gordon T. Geballe, now president, brings an environmental and legal background that reinforces the foundation's climate and environmental giving.

The foundation favors organizations with demonstrated Bay Area roots or direct Bay Area programming. California receives 80% of all grants by count, with San Francisco, the Peninsula, and the East Bay dominating. Current multi-year grantees — Environmental Defense Fund, NRDC, Nature Bridge, Fred Hutchinson Cancer Research Center, Kickstart International — have each received 3 or more consecutive grants, signaling the foundation rewards institutional loyalty and consistent results.

First-time organizations must understand this is a patient, relationship-first process. There is no LOI, no formal proposal stage, and no grant cycle. Richard Horan, Director of Grants (the only paid staff member), and family board members Gordon T. Geballe, Alison F. Geballe, and Adam P. Geballe are the key decision-makers. Organizations should budget 12–24 months for cultivation before expecting a first grant.

Across 183 recorded grants totaling $15,867,834 in the public database, the Eucalyptus Foundation shows a clear barbell distribution: a high volume of recurring modest grants in the $25,000–$100,000 range anchoring a community portfolio, punctuated by transformative multi-year investments reaching $500,000–$1.5 million cumulative.

Key grant metrics: Average grant: $86,709. Median grant: $37,500. Stated typical grant range: $500–$500,000. The spread between mean ($86,709) and median ($37,500) reflects the barbell structure — a handful of large commitments pull the average well above the typical gift.

Annual giving trends (990-PF): $3.76M (2012) → $3.82M (2013) → $3.97M (2014) → $4.45M (2016) → $5.95M (2019) → $6.27M (2020) → $5.14M (2021) → $6.10M (2022–2023) → $6.2M (2024). Giving has grown roughly 65% over 12 years and stabilized at $6.1–6.2 million annually since 2019. Notably, annual giving has not yet scaled to match the $149M asset infusion received in 2022, suggesting capacity exists for significant distribution increases.

Top cumulative grantee commitments: Fred Hutchinson Cancer Research Center $1,500,000 (3 grants, medical research); Environmental Defense Fund $1,300,000 (3 grants, Climate Corps Fellowship); UC Merced Foundation $825,000 (3 grants, arts programming); Yale University $800,000 (2 grants, School of Public Health); French American International School $750,000 (3 grants, new facility); Kickstart International $750,000 (3 grants, Africa economic development); Middlebury College/MIIS $750,000 (3 grants, environmental education); Nature Bridge $750,000 (3 grants, National Environmental Science Center).

By focus area (estimated from grantee purpose data): - Environment and climate: ~25% — Environmental Defense Fund, NRDC, Nature Bridge, Middlebury, Friends of the Urban Forest, Seacology - K-12 and youth education: ~22% — Eastside College Prep, Boys & Girls Clubs Peninsula, Ravenswood, Aim High, Playworks, San Francisco Symphony - Arts and culture: ~18% — UC Merced Foundation, International Festival of Arts & Ideas, Outside the Frame - International development: ~12% — Kickstart International, Geohazards International, Build Change - Higher education: ~8% — Yale School of Public Health, UC Berkeley - Human services and housing: ~10% — LifeMoves, Tenderloin Neighborhood Development, Huckleberry Youth - Medical research: ~5% — Fred Hutchinson Cancer Research Center

Geographic distribution: 147 of 183 grants (80.3%) went to California. Out-of-state grants primarily fund national organizations with Bay Area presence or US-based intermediaries for international programs.

The Eucalyptus Foundation occupies a distinctive mid-tier position among Bay Area family foundations — large enough to sustain multi-year six-figure grants but operating with the informal culture of a much smaller entity. The table below compares it to comparable Bay Area family foundations; figures marked with ~ are approximations based on public 990 data and industry sources.

Eucalyptus stands out for its breadth across verticals relative to peers of similar size. The Walter S. Johnson Foundation focuses narrowly on K-12 education; Columbia Foundation concentrates on arts and social justice. Eucalyptus spans all of these plus international development and medical research — reflecting a portfolio built on family interests rather than strategic program focus.

The foundation's payout rate (~2.3% on $265M assets) is the most striking anomaly relative to peers. Private foundations are required to distribute at least 5% of qualifying assets annually — a threshold that implies Eucalyptus may need to more than double annual giving in the coming years to comply. This is almost certainly a transitional artifact of the transformative $149M contribution received in 2022, and grant seekers should view the current $6.1M giving level as a floor, not a ceiling. By contrast, the Osher Foundation and Koret Foundation operate at payout rates more consistent with the 5% minimum.

No significant public news or press releases were identified for the Eucalyptus Foundation in 2025–2026, consistent with its extremely low public profile. The foundation does not issue press releases, maintain an active website (eucalyptus.org returns only "OK"), or participate in philanthropy media. The following developments are drawn from 990-PF filings and grant database records.

Founding President's Death (October 23, 2021): Theodore H. Geballe, Stanford physics professor emeritus and former Bell Labs researcher celebrated for pioneering work in superconductivity, died at age 100. His name appears in 990-PF filings with the notation "Dec'd 102321." His 30-year leadership of the foundation shaped its science education portfolio (Eastside College Prep physics, $441K; American Physical Society PhysicsQuest, $200K) and research institution relationships. Gordon T. Geballe, his son, assumed the presidency.

Major Asset Infusion (FY2022): The foundation received $149,112,188 in contributions in FY2022 — a transformational event that nearly tripled total assets from $60.5M to $208.5M in a single year. This appears to reflect a large estate gift or inter-family transfer. Annual giving remained at ~$6.1M, creating a compressed payout ratio that will likely force giving increases in 2025–2027.

Professionalization of Grant Staff: Richard Horan's addition as a compensated Director of Grants ($62,500/year) — visible in recent filings but absent from older records — represents the first professional grant staff in the foundation's history. Prior filings show all officers serving as volunteers.

Sustained Portfolio Continuity: Environmental Defense Fund, Nature Bridge, Fred Hutchinson Cancer Research Center, and Kickstart International each maintain 3-grant histories in the database, indicating these core relationships have continued without disruption through the leadership transition.

Given the foundation's invitation-only structure, the "application" process is entirely a relationship cultivation exercise with no formal stages, deadlines, or review cycles. The following advice is specific to Eucalyptus Foundation's documented practices.

Use the only public contact channel: Email inbox@eucalyptusassoc.com with a brief 2–3 paragraph introduction letter. Address it to Richard Horan, Director of Grants. Include: (1) your organization name, founding year, and location; (2) the specific program you want to fund and its target population; (3) one compelling outcome metric from the past 12 months; (4) a clear connection to the Geballe family's documented interests. Do not send a full proposal, budget, or attachments in the initial contact.

Connect through current grantees. A warm introduction from Environmental Defense Fund, Boys & Girls Clubs of the Peninsula, Nature Bridge, Eastside College Prep, or Geohazards International is worth more than any cold email. Map your board and staff relationships to identify shared connections with current Eucalyptus grantees.

Lead with science, climate, or Bay Area community impact. The Geballe family's intellectual roots in physics and environment mean proposals emphasizing science education, climate solutions, Bay Area youth access to STEM, or marine conservation are inherently aligned. The $1.3M to Environmental Defense Fund's Climate Corps and $441K to Eastside College Prep's physics program demonstrate these are not incidental priorities.

Align your language with their documented grant purposes. Study the exact phrases from their grantee records: "Climate Corps Fellowship Program," "National Environmental Science Center," "High School Physics Program," "Economic Development - Africa," "Hispaniola and South Asia Collaborative Exchanges." Mirror this action-outcome framing in your pitch.

Frame for multi-year partnership from day one. Every major grantee shows 3 consecutive grants. A first ask of $50,000–$100,000 framed as year one of a three-year $300,000 commitment resonates more than a one-time project request.

Avoid these common mistakes: (1) Sending a full unsolicited proposal — it will not be reviewed; (2) Positioning as a national organization without Bay Area ties — 80% of grants go to California; (3) Making a financial ask in the first contact; (4) Focusing on abstract mission statements rather than specific programs with measurable outputs.

No formal timing window exists. Grantmaking appears continuous year-round. Reach out when your program story is strongest, not when you think a deadline window is open.
