John Joseph Paul Studzinski, CBE, is a prominent British-American investment banker, philanthropist, and art collector born on March 19, 1956, in the United States. He began his career in finance after earning a Bachelor of Arts in Government from Bowdoin College in 1978 and a Master of Business Administration from the University of Chicago Booth School of Business in 1983. Studzinski joined Morgan Stanley in 1987, rising to become a Managing Director and Global Head of Mergers and Acquisitions in Europe, where he played a key role in major deals and established himself as a leading figure in international finance. In 2002, he co-founded the strategic advisory firm Hakluyt & Company, which provides intelligence and advisory services to global corporations, and served as its managing partner until 2011. Following stints at Blackstone and Apollo Global Management, he joined PIMCO in September 2018 as Managing Director and Vice Chairman, focusing on global investment management and client relations.

Beyond finance, Studzinski is deeply committed to philanthropy, serving as Chairman of the Strategy Committee of the Smith Institute and as a trustee for organizations such as the National Gallery in London and the 21st Century Trust. He co-founded the 21st Century Foundation, which supports initiatives in education, health, and social justice worldwide. In 2011, he married Jane Harman, the former U.S. Congresswoman and President of the Woodrow Wilson International Center for Scholars, blending their personal and professional networks across the Atlantic. An avid art collector specializing in contemporary works, Studzinski has donated significant pieces to institutions like the Tate Modern and supports cultural preservation efforts.

Recognized for his contributions, Studzinski was appointed Commander of the Order of the British Empire (CBE) in 2009 for services to philanthropy and the arts. His career exemplifies a bridge between Wall Street and the City of London, influencing global economic and charitable landscapes through strategic advisory, investment leadership, and civic engagement.
