On the eve of the American Revolution, Pennsylvania Hospital opened its doors as a provincial charity for the physically and mentally ill. In a matter of decades, it became not only America's first "voluntary" hospital, but also the home of the first apothecary, medical library and surgical amphitheatre. From its radical conception by a group of extraordinary colonists, the hospital has evolved into a world-renowned facility that treats over 225,000 patients a year. In A History of the Pennsylvania Hospital, Kristen Graham introduces the people and ideas that guided the Pennsylvania Hospital through numerous wars and social and economic crises, landing it at the forefront of healing, learning and innovation.
