BALTIMORE -- New York City Mayor Michael Bloomberg has given $350 million to his alma mater, Johns Hopkins University.
The gift announced Saturday means the financial services magnate and philanthropist has topped $1 billion in total giving to the private Baltimore university where he graduated in 1964.
The university says $250 million from the latest donation will go to a variety of cross-disciplinary subjects, including water resources, health care, global health, the science of learning and urban revitalization.
The remaining $100 million will go to need-based financial aid for undergraduate students, awarding 2,600 Bloomberg scholarships in the next 10 years.
The mayor says he doesn't know any "other institution that can make a bigger difference in lives around the world through its groundbreaking research_especially in the field of public health."
