The DeLamar Institute of Public Health at Columbia University was founded in 1922 with a mandate to "study and [teach] the origins and cause of human disease and the prevention thereof." The precursor to Mailman School of Public Health, the Institute demonstrated from the beginning the core values that have shaped this institution for 90 years.

Today, the Mailman School of Public Health is recognized as an international thought leader addressing critical public health issues ranging from emerging infectious diseases and urban health disparities to the implications of health policy decisions. The Mailman School is committed to creating knowledge, translating science for impact, and educating the next generation of public health leaders.
