Joan and Sanford Weill pledged $120 million to UC Davis—the largest gift ever for veterinary medicine—funding a new small‑animal teaching hospital and expanding One Health research that links animal and human disease. Two‑thirds of the gift will underwrite a hospital that integrates artificial intelligence and precision medicine into diagnostics and clinical trials. UC Davis said the donation will increase clinical capacity and boost translational research across species, from cancer to neurological conditions. The gift repositions veterinary medicine as a research and clinical hub with crosswalks into human health, while highlighting philanthropic appetite for applied biomedical infrastructure at public research universities.
