Art Samberg, an alumnus of Columbia Business School who led major hedge funds, donated $25 million to help build the school's new Manhattanville Campus in New York City. The campus, designed by Diller Scofidio + Renfro and under construction since 2008, will feature two buildings totaling 492,000 square feet to create more learning space and a high-tech environment for Columbia Business School students. It will be shared with other Columbia schools and is scheduled to fully open in 2021.
