About ARNOLD S LEONARD CANCER RESEARCH FUND

The Arnold S Leonard Cancer Research Fund (doing business as Dr. Leonard’s Cancer Research Fund) is a Minnesota-based 501(c)(3) established to continue the research legacy of Dr. Arnold S. Leonard. The fund raises and directs donor support to laboratory research at the University of Minnesota focused on bacterially delivered anticancer immunotherapies and related genetic-engineering approaches.

The organization operates as a small grantmaking and fundraising charity: it runs donor-facing events and public appeals and channels donated dollars to University of Minnesota research programs (working through entities such as the Minnesota Medical Foundation). Recent public filings and the charity website show ongoing lab updates and fundraising activity in 2023–2024, and the fund reports that 100% of donated funds are directed to the research program it supports.
