CAMBRIDGE -- Two and a half years ago, biology researchers at MIT were discussing their work with an outside advisory committee. What could help you in your job, they were asked. One simple answer came from the women in the room: child care.
David H. Koch, a billionaire philanthropist and MIT graduate, had attended dozens of these meetings over the past few decades, but had never been so moved.
Koch, who had already given the Massachusetts Institute of Technology about $150 million to found a cancer research institute and endow faculty positions, decided to spend $20 million more, on a fund to support the building of a new center for 126 infants, toddlers, and preschoolers, as well as scholarships and programs.
