Mr. Schwarzman has been involved in all phases of Blackstone’s development since its founding in 1985. The firm has established leading investing businesses across asset classes, including private equity, where it is a global leader in traditional buyout, growth equity, special situations and secondary investing; real estate, where it is currently the largest owner of commercial property in the world; hedge fund solutions, where it is the world’s largest discretionary hedge fund investor; and credit, where it is a global leader and major provider of credit for small, middle-market and other companies. Blackstone also has major businesses dedicated to infrastructure and life sciences investing, as well as delivering the firm’s investment management expertise and products to insurance companies.
 
Mr. Schwarzman is an active philanthropist with a history of supporting education, as well as culture and the arts, among other things. In 2020, he signed The Giving Pledge, committing to give the majority of his wealth to philanthropic causes. In both business and philanthropy, Mr. Schwarzman has dedicated himself to tackling big problems with transformative solutions. In June 2019, he donated £150 million to the University of Oxford to help redefine the study of the humanities for the 21st century. His gift – the largest single donation to Oxford since the renaissance – will create a new Centre for the Humanities which unites all humanities faculties under one roof for the first time in Oxford’s history, and will offer new performing arts and exhibition venues as well as a new Institute for Ethics in AI. In October 2018, he announced a foundational $350 million gift to establish the MIT Schwarzman College of Computing, an interdisciplinary hub which will reorient MIT to address the opportunities and challenges presented by the rise of artificial intelligence, including critical ethical and policy considerations to ensure that the technologies are employed for the common good.

In 2013, he founded an international scholarship program, “Schwarzman Scholars,” at Tsinghua University in Beijing to educate future leaders about China. At over $575 million, the program is modeled on the Rhodes Scholarship and is the single largest philanthropic effort in China’s history coming largely from international donors. Mr. Schwarzman is Co-Chair of the Board of Trustees of Schwarzman Scholars. In 2007, Mr. Schwarzman donated $100 million to the New York Public Library on whose board he serves.
