Jewish donor David M. Einhorn, the founder and owner of Greenlight Capital, has pledged $50 million to the Children’s Hospital of Philadelphia to build a first-of-its-kind institute for early relational health. Early relational health refers to “the mutual, meaningful, and affirming moments of connection in the youngest relationships that are fundamental to healthy development,” according to the release. That made CHOP “uniquely positioned” to use early relational health research in “clinical practice, medical education, and training for future healthcare leaders,” the release said. The Einhorn Institute will be part of CHOP’s Research Institute. Dr. Dani Dumitriu will serve as its inaugural director and David M. Einhorn Endowed Chair in Early Relational Health on Jan. 1, 2027.
