Members of the Harvard Medical School community have also excelled in the research arena. Faculty members have been making paradigm-shifting discoveries and achieving "firsts" since 1800, when HMS Professor Benjamin Waterhouse introduced the smallpox vaccine to the United States. Their accomplishments are recognized internationally, and, in fact, fifteen researchers have shared in nine Nobel prizes for work completed while at the School.
The Faculty of Medicine includes more than 11,000 individuals working to advance the boundaries of knowledge in labs, classrooms and clinics. The school's main quadrangle in Boston houses 146 tenured and tenure-track faculty members in basic and social science departments as well as classrooms where students spend their first two years of medical school.
