Harry C. Trexler Trust

The Harry C. Trexler Trust was founded in 1935 from the estate of General Harry C. Trexler, a Lehigh Valley industrialist whose holdings spanned lumber, cement, power, and telephone companies. Trexler left the bulk of his estate to the trust, naming the City of Allentown as its primary beneficiary for park maintenance and improvement. A separate philanthropic mandate directs remaining income to charitable organizations across Lehigh County, with annual grants supporting education, social services, and the arts. The trust operates as a grantmaking foundation rather than an active investment vehicle. Its capital is deployed conservatively — predominantly in fixed-income and public-equity portfolios — to generate steady distributable income. Grantmaking concentrates locally: the City of Allentown's park system receives the largest share annually, funding maintenance for Trexler Park and other green spaces. Additional grants flow to Lehigh County nonprofits, including the Allentown Art Museum, which houses the Harry C. Trexler Collection of decorative arts and paintings. The trust is administered by a board of trustees that has historically included local business and civic leaders. L. Charles Marcon, a trustee and the former CEO of Duggan and Marcon, served as President of the Lehigh Valley Partnership. Fellow trustee Donald M. Bernhard previously directed community affairs at PPL Corporation. Janet Roth serves as CEO and is an active member of the Allentown Rotary Club. The trust also holds direct real estate assets: the Trexler Nature Preserve in Lowhill and North Whitehall Townships and the historic Springwood residence in Allentown. Structurally, the trust is locked in perpetual local obligation — a model resembling a municipal endowment rather than a private foundation with discretionary global reach. Unlike family offices that flexibly shift mandates across generations, the Trexler Trust's geographic and programmatic boundaries are fixed by its charter. That constraint creates a durable, multi-decade funding stream for one Pennsylvania county's civic infrastructure, insulating Allentown's parks and charitable sector from political budget cycles.

Frequently asked questions

What is the relationship between the Trexler Trust and the City of Allentown?

The City of Allentown is the trust's primary beneficiary, receiving the largest annual share of income for park maintenance and improvement. This arrangement originates from Harry C. Trexler's will, which directed the trust to care for Allentown's park system in perpetuity. The city does not control the trust's investment or distribution decisions — those remain with the board of trustees — but it submits annual requests for park-related funding. Major assets include Trexler Park and the Trexler Nature Preserve.

How does the trust invest its capital?

The trust pursues a conservative, income-oriented strategy typical of perpetual charitable trusts, predominantly allocated to fixed-income and public-equity portfolios. It is not an active venture, private-equity, or direct-deal investor. The investment approach prioritizes capital preservation and steady distributable income to meet annual grant obligations. Specific portfolio holdings and external managers are not publicly disclosed.

Who makes investment and grantmaking decisions?

A board of trustees governs both investment policy and grantmaking. Trustees have historically included Lehigh Valley business and civic leaders; current members include L. Charles Marcon and Donald M. Bernhard. Day-to-day operations are managed by a CEO — currently Janet Roth — and a small staff. Grant decisions follow the trust's charter mandate, which restricts charitable distributions to Lehigh County organizations.

Does the trust make grants outside Lehigh County?

No. The trust's charter restricts its charitable grantmaking to organizations serving Lehigh County, Pennsylvania. The only exception is its direct support for Allentown's park system, which is separately mandated. Organizations outside Lehigh County are not eligible for funding, making this one of the more geographically constrained private foundations of its size.

What is the trust's connection to the Allentown Art Museum?

The Allentown Art Museum houses the Harry C. Trexler Collection, a group of decorative arts and paintings acquired by Trexler during his lifetime. The trust has historically provided grant support to the museum. The collection represents one of the few cultural assets tied directly to the Trexler name outside the trust's park holdings.

Is the Trexler Trust structured as a private foundation or a family office?

It is a private foundation under IRS classification, not a family office. It has no family members involved in governance and operates with an independent board of trustees. The trust exists to fulfill Harry Trexler's specific charitable and civic directives rather than to manage wealth for descendants — Trexler had no surviving children.

Where did Harry Trexler's wealth originate?

Harry C. Trexler amassed his fortune through diversified industrial holdings in the late 19th and early 20th centuries, primarily in lumber, cement manufacturing, electric utilities, and telephone companies concentrated in Pennsylvania's Lehigh Valley. He was a founder of the Lehigh Portland Cement Company and held extensive timberlands. This multi-industry base generated the capital that ultimately endowed the trust.
