Eliminating hookworm in the South. Instituting high standards at American medical schools. Saving diabetes patients by testing and distributing insulin. Discovering the flu virus. Decimating HIV’s death rate. These are just a handful of the many notable achievements in medicine that owe their success to the generosity of American philanthropists. Some of them are fascinating stories—how Uncas Whitaker’s $700 million fortune almost singlehandedly made biomedical engineering the thriving field that it is today, giving us cochlear implants, artificial hearts, lab-grown skin, and more. Some are harrowing—how at least eight researchers working for the Rockefeller Foundation died trying to find a yellow fever vaccine. All are inspiring for donors interested in medical research and saving lives. The Philanthropy Roundtable has researched and compiled a roster of the most important U.S. philanthropic achievements in medicine throughout nearly three centuries. It is now online here on the Roundtable’s website. More roundups of major philanthropic achievements are on the way as part of our creation of a comprehensive almanac of philanthropy.
