We match the street line and ZIP code as the IRS gives them, ignoring case and outer spaces and nothing else, so "AVE" and "AVENUE" count as different streets and this list can miss some. A shared address can mean related organizations or a shared office, but it can also be a registered agent, a mail drop or a service provider holding mail for unrelated clients. It is not, by itself, evidence that two organizations are connected.

Mission and programs · 2024

Mission

Winterthur builds upon the vision of Henry Francis du Pont to inspire and educate through its collections, estate, and academic programs by engaging diverse audiences in the study, preservation, and interpretation of American material culture, art, design, and history.

Activities or mission (Part I)

Winterthur's mission is to preserve and enhance the legacy of its founder, Henry Francis du Pont, for the benefit and enjoyment of the public, including: the care, development, and study of its preeminent collection of decorative and fine arts made or used in America; the enhancement and interpretation of one of America's finest naturalistic gardens; the operation of graduate programs in American material culture and art conservation at the highest academic level; the operation and development of a library to support these important cultural goals; and the preservation of the historically important buildings and grounds.

  • Public Visitation and Exhibitions:Winterthur welcomed more than 130,000 visitors to the museum, estate, and gardens, Major exhibitions and large-scale public events, including Transformations: Contemporary Artists at Winterthur and the annual Artisan Market highlighted both the historic collection and the work of contemporary artists. Attendance growth was supported by a robust calendar of exhibitions, family programs, and community events, as well as strong participation in free and subsidized offerings.In September 2024, Winterthur hosted its annual Discover Winterthur event, during which admission was waived and visitors were invited to experience a wide range of programs across the property. Fifteen community partners participated by hosting informational tables, nearly 1,300 individuals attended.Winterthur also emphasized contemporary artistic practice through Transformations: Contemporary Artists at Winterthur, an exhibition featuring artists inspired by the museum's collection and gardens. In addition, the annual Artisan Market in July 2024 showcased 110 working artists, awarded grants to three artists, and attracted more than 6,500 visitors, reflecting continued year-over-year growth and strong public interest.Seasonal family programming further extended Winterthur's reach. During July and August 2024, Terrific Tuesdays offered significantly discounted admission for families with children, paired with hands-on activities across the estate. These same activities were also delivered free of charge to low-income childcare centers through outreach visits, ensuring that children unable to travel to Winterthur could still benefit from our educational resources.

    Expenses $20,918,833 · Revenue $2,463,092

  • Education and School Programs:Winterthur continued to expand its educational reach through free school programs, including onsite field trips, virtual offerings, and in-classroom experiences. Nearly 17,000 students participated in Winterthur programs during the fiscal year, making education one of the organization's largest programmatic investments. These programs included free admission and transportation support, as well as complimentary return passes for students and their families, increasing access for diverse audiences.Educational programming remained a cornerstone of Winterthur's mission. Nearly 17,000 students participated in programs during the fiscal year, an increase from just over 14,000 the prior year. School program participants represent Winterthur's most diverse audience. Each student received a complimentary pass to return with family and friends; approximately 400 passes were redeemed, accounting for an estimated 1,600 additional free visitors.

    Expenses $2,712,338 · Grants $586,171 · Revenue $412,347

  • Community Engagement and Access Initiatives:Winterthur advanced its commitment to community access through free and discounted admission days and partnerships with regional nonprofit organizations. Programs such as Discover Winterthur and Terrific Tuesdays offered waived or reduced admission costs, expanded outreach to new and infrequent visitors, and provided opportunities for community partners to engage directly with the public. These initiatives involved both direct program expenses and allocations supporting partner participation.

The first 25 listed. Compensation is as filed in Part VII: reportable pay from this organization and from related organizations, other compensation, and hours per week. The total, marked calculated, is our sum of the three dollar columns, with a blank column counted as $0; the form itself has no total. On a Form 990-EZ the columns are Part IV's instead, and on a Form 990-PF Part VIII's — compensation, contributions to benefit plans, and expense account — and the total sums those. A Schedule J breakdown is as filed: base pay, bonus, other, deferred compensation and nontaxable benefits from this organization, with any from related organizations beside each, and the filer's own total. It is shown with the Part VII listing of the same name on the same return. The form gives no key between the two, so that pairing is ours, and is marked matched by us. Earlier years are each on their own filing page.

Nonprofiteer parses Forms 990, 990-EZ and 990-PF, in a window of recent tax years. These returns are recorded from the IRS e-file index, so their figures were extracted by that index rather than read from the return here — treat them as a different source from the filings above, not as more of the same record. A dash means the index carries no figure; Form 990-T listings carry none at all. Showing the 10 most recent; the API carries the rest.

Auto-Revocation List

Not listed. The IRS publishes this list for organizations whose exemption was automatically revoked for failing to file for three consecutive years.

Publication 78

Listed as of 13 October 2026, under deductibility PC.

These are two separate IRS files on two separate schedules, shown as published and not reconciled with each other. Neither is a statement about whether a contribution is deductible today: 19,245 organizations appear in Publication 78 while the IRS's own revocation file lists them as currently revoked, more than half of those revoked before 2019. Absence from Publication 78 is evidence of nothing, and presence is not evidence either. Verify current status with the IRS before relying on it.
