Harvard University announced a $350 million gift — the largest in Harvard’s history — to support efforts at the School of Public Health (HSPH) to tackle the world’s toughest health challenges. The gift comes from Newton, Mass.-based The Morningside Foundation, established by the family of the late T.H. Chan, which has focused its philanthropy primarily on education, health, and faith-based organizations in North America and Asia. The gift will also lead to the renaming of the School, which will be called the Harvard T.H. Chan School of Public Health.
