As we reflect on America at 250, we can see moments when this country, still young and unfinished, quietly changed the world. In 1751, Thomas Bond and Benjamin Franklin founded Pennsylvania Hospital just as observation-based medicine took hold.

It emphasized clinical observation and shared learning, turning individual care into repeatable knowledge and helped define the academic medical center.

Benjamin Franklin and Thomas Bond founded Pennsylvania Hospital to serve Philadelphia’s most vulnerable.

From Brian

Pennsylvania Hospital showed us how care could become something that learns, improves, and spreads.
