Essel Foundation Inc.

The Essel Foundation is a family foundation in the truest sense — its entire philanthropic identity flows from the Lieber family's personal commitment to brain science and mental health. Founded in 1966 and headquartered at 2500 Westchester Avenue in Purchase, New York, this foundation operates with a tightly controlled giving philosophy: all grants are preselected, no public applications are accepted, and the foundation maintains no public website or listed contact information beyond its IRS filings.

The president, Geoffrey Simon, and secretary, Janice Lieber, run operations with zero officer compensation across all available filing years — a hallmark of family stewardship rather than institutional philanthropy. This is not a program-officer-driven grantmaker with formal review panels; it is an extension of a family's direct philanthropic relationships.

The foundation's approach centers on deep, sustained partnerships with a small number of institutions. The Lieber Institute for Brain Development — named for the founding family and based in Baltimore, Maryland — has received 8 grants totaling $45 million, representing approximately 73% of all tracked giving. This is not grant-making in the conventional sense; it is family-directed institution-building. The Brain & Behavior Research Foundation has received roughly $12.4 million across 9 recorded grants. Columbia University's Department of Psychiatry represents a third anchor relationship, culminating in a transformational $10 million gift to launch the Dr. Herbert Pardes Scholars Initiative.

Organizations outside the current grantee ecosystem should understand this is not a foundation to cold-approach. The Lieber family gives primarily to organizations where they have personal relationships, institutional trust built over years, and direct visibility into research outcomes. The occasional grants to Williams College ($1.2M), The Carter Center ($155K), HeartShare Human Services ($15K), and Adam's Camp New England ($5K) likely reflect personal connections rather than programmatic expansion.

Given the massive asset growth in FY2024 — from $109.7M to $270.4M with $172.5M in contributions received — the foundation may be entering an expansion phase. Organizations in translational neuroscience, psychiatric genomics, and early-career researcher development should monitor any signals that the foundation is broadening its portfolio.

Essel Foundation's grant-making shows extreme concentration paired with significant year-to-year volatility. Across 33 tracked grants totaling $61.75 million, the average per-grant award is $1.87 million — but that figure is heavily skewed by the Lieber Institute relationship. Using the foundation's own disclosed typical grant data for recent years: median grant is $200,000, average $528,333, with a range from $5,000 to $2.4 million.

The single dominant grant stream is the Lieber Institute for Brain Development (Baltimore, MD): 8 grants totaling $45 million, or 73% of all recorded giving. Individual Lieber Institute awards have ranged from approximately $1 million to at least $2.4 million per grant, all with unrestricted designations. The Brain & Behavior Research Foundation is the second-largest recipient at roughly $12.4 million across 9 grants, primarily for schizophrenia, depression, and psychiatric disorder research.

Smaller grants reveal a broader but much thinner philanthropic reach. Williams College has received 4 unrestricted grants totaling $1.2 million. Columbia University entities account for another $2.7 million across 6 recorded grants. Outlier grants include: Youth Anxiety Center NYP Fund Inc ($200,000), The Carter Center Inc ($155,000), University of Florida ($50,000), University of South Florida ($25,000), HeartShare Human Services of New York ($15,000), and Adam's Camp New England ($5,000).

Annual giving has been highly variable: $635K in FY2018, $3.17M in FY2019, $18.45M in FY2020 (peak), $13.45M in FY2021, $13.23M in FY2022, $5.68M in FY2023. FY2024 giving is approximately $14.79M across 6 awards, a significant recovery. This pattern reflects lumpy, relationship-driven deployment that spikes when anchor institutions need capital and contracts during accumulation phases — not a predictable annual payout schedule.

Geographically, New York (14 grants) and Maryland (8 grants) dominate, reflecting headquarters proximity and the Baltimore-based Lieber Institute. Massachusetts (4 grants, primarily Williams College), Nebraska (3 grants), and Florida (2 grants) round out the footprint. All grants on record carry unrestricted designations, signaling complete institutional trust.

The following table compares Essel Foundation to four foundations with overlapping focus in neuroscience, psychiatric research, and mental health.

Essel operates at a comparable asset level to Dana and McKnight's neuroscience endowment but with dramatically more concentrated giving — fewer grantees, deeper relationships, and no competitive process whatsoever. The irony is that Brain & Behavior Research Foundation, which runs an open peer-reviewed grant competition, is itself one of Essel's largest grantees — the foundation funds a funder. The Simons Foundation comparison illustrates a plausible long-term trajectory: if the Lieber family continues capitalizing Essel at the FY2024 pace, this foundation could approach Simons-level capacity within a decade, making today's relationship-building investments potentially very high-value.

The most consequential recent development is Essel Foundation's dramatic balance sheet expansion in FY2024. Total assets grew from $109.7 million (FY2023) to $270.4 million (FY2024), driven by $172.5 million in new contributions — likely a major personal gift from the Lieber family, a significant realized investment event, or a planned capital deployment. This nearly 150% asset increase is the largest single-year change in the foundation's recorded history and strongly suggests an imminent ramp-up in grant-making activity.

The Columbia University $10 million gift establishing the Dr. Herbert Pardes Scholars Initiative is the most publicly documented major recent grant, though its exact announcement date is not confirmed in available web sources. The initiative honors Dr. Herbert Pardes, the former Columbia Psychiatry chair and longtime Lieber family associate, and funds junior faculty development in mental health research — a notable programmatic evolution toward career-stage philanthropy.

Total giving in FY2024 reached approximately $14.79 million across 6 awards, recovering sharply from the $5.68 million low in FY2023. No press releases, new program announcements, staff changes, or formal grant cycles were identified through web research. The foundation operates in deliberate obscurity: no public website, no social media presence, and no publicly listed phone number or email. Geoffrey Simon has served as president across all available filing years with no leadership changes, and all officers continue to serve without compensation.

Because Essel Foundation operates exclusively by invitation, standard grant-writing advice does not apply. The strategic imperatives are entirely about relationship development, and the timeline should be measured in years, not grant cycles.

Map your institutional connections first. The Lieber name appears on the foundation's own leadership (Janice Lieber, secretary) and its flagship grantee (Lieber Institute for Brain Development). Any institutional connection to Steve or Connie Lieber, or to Geoffrey Simon, should be documented and activated through your development office.

Attend the right scientific venues. The foundation's grantees cluster around psychiatric genetics, schizophrenia research, and brain development — the research community anchored by Daniel Weinberger (Lieber Institute) and the Brain & Behavior Research Foundation's scientific advisory network. Conferences including the Society of Biological Psychiatry annual meeting, ACNP (American College of Neuropsychopharmacology), and the World Congress of Psychiatric Genetics are where this ecosystem convenes.

Leverage warm introductions aggressively. A referral from a Lieber Institute principal investigator, a Columbia Psychiatry faculty member, or a BBRF grantee is vastly more valuable than any cold outreach. Ask your department chair and research dean whether any prior contact history exists with the foundation.

Emphasize unrestricted giving compatibility. Every single recorded grant purpose is 'unrestricted.' Frame any pitch around institutional mission alignment and long-term research impact — not specific deliverables, quarterly milestones, or accountability structures. This foundation wants to fund institutions it trusts, not manage projects.

Be patient and consistent. Williams College has received 4 grants over multiple years at modest sizes. The foundation rewards long-term relationships before scaling up. A first engagement, if it comes, will test the relationship before significant capital follows.
