On Aug. 20, 1810, Drs. James Jackson and John Collins Warren penned a petition calling for the establishment of a general hospital in Boston. This petition -- known as the Circular Letter -- called for a new hospital to provide healthcare for the poor and disenfranchised. In 1811, the Massachusetts legislature granted a charter for the incorporation of the Massachusetts General Hospital, becoming just the third general hospital in the United States.

Now entering our third century, the founders' vision for Mass General remains embedded in the fabric of the institution and the whole world has become our neighbor. Founded in 2006, the Center for Global Health builds on the hospital’s rich history of leadership in clinical care, medical education and humanitarian aid while crafting innovative solutions to some of the most intractable challenges facing our global community.
