…Six years ago, at the end of the Great Recession, Mayor Michael Bloomberg solicited proposals for a school that could anchor and nurture the city’s incipient tech sector. The idea was to help the city diversify away from the financial services industry that had been the economy’s bedrock until it started to crack during the crisis. In September Cornell Tech—a collaboration between Cornell University and Technion-the Israel Institute of Technology—will open the first buildings on its Roosevelt Island campus, a 12-acre, $2 billion complex seeded with $100 million in city funds. They include the Bloomberg Center, an academic building, and The House, a residential complex. The third building, known as The Bridge, will facilitate the collaboration of industry and academia with the aim of creating technology companies that run on serious science and serve the city’s traditional industries, most notably advertising, fashion, finance, media and medicine.
