[Medical philanthropy in the United States].

Philanthropic foundations played a crucial role in rationalizating and organizing American society in the late 19th and early 20th centuries. The promotion of science was applied to medical reform, leading to the advent of genuine medical research within the framework of brand-new university hospital faculties. With the two world wars, the state became heavily involved in the field of healthcare. After 1945, it became the main source of funding for biomedical research. Philanthropy did not disappear from the institutional landscape; it continued to work in tandem with public authorities. Its role in medical research is now minor in terms of funding volume, but a strategic one in the development of projects aimed at advancing basic science and knowledge of various diseases.
