Harvard T.H. Chan School of Public Health traces its roots to public health activism at the beginning of the last century, a time of energetic social reform. From the start, faculty were expected to commit themselves to research as well as teaching. In 1946, no longer affiliated with the medical school, HSPH became an independent, degree-granting body. Today, the Harvard T.H. Chan School of Public Health brings together dedicated experts from many disciplines to educate new generations of global health leaders and produce powerful ideas that improve the lives and health of people everywhere. We work together as a community of leading scientists, educators, and students to take innovative ideas from the laboratory to people’s lives, not only making scientific breakthroughs, but also working to change individual behaviors, public policies, and health care practices.
