The foundation concentrates its giving on a mix of large institutional endowments and local community support, with major multi-year commitments to higher education (notably Duke Law) alongside substantial support for medical research—especially tumor and cancer-related causes—and Jewish communal life in Cleveland. Smaller, recurring gifts fund local hospitals, cultural organizations, day schools and Israel-related groups, signaling both national-impact investments and neighborhood-level philanthropy.
Richard Horvitz and Erica Hartman-horvitz Foundation’s giving is marked by a $2,000,000 grant to Duke University of Law School for its Constitutional and Public Law Program, with additional support to the school’s Public Law Program, financial aid endowment, student fellowship fund, and Dean Levi Fund. That law-school series sits alongside major support for medical research and Cleveland institutions, showing a pattern that combines high-dollar institutional commitments with recurring local gifts. The foundation’s recent grants also include $666,666 to Children’s Tumor Foundation for Discovery Fund work and $500,000 to University Hospitals for the Ahuja Medical Center. Those awards align with other grants tied to cancer, neurofibromatosis, and clinical care, including support for University Hospitals Seidman Cancer Center and Case Western Reserve University School of Medicine. A separate cluster of grants supports Jewish communal life and education in Cleveland, including the Jewish Federation of Cleveland and Temple Emanu El, while smaller gifts reach arts, schools, and relief groups.
The foundation supports medical research tied to tumors, cancer, and related clinical work.

It also funds legal education and public-law programming. Duke University of Law School received $2,000,000 for the Constitutional and Public Law Program, $300,000 for the Public Law Program, and $125,000 for the Horvitz Financial Aid Endowment Fund. Jewish communal institutions are another clear focus. The Jewish Federation of Cleveland received $855,000 for general and unrestricted support, and Temple Emanu El received $50,000 for the Vision Campaign and $6,000 for the Rabbi Roberts Book Project. The foundation also makes grants for humanitarian and community-support purposes, including $25,000 to Jewish Federation of Cleveland for the Ukraine Relief Fund and $50,000 to Friends of the Israel Defense Forces for Lone Soldier’s Apartment.
