James Gerard Dinan (born 1959) is a prominent American hedge fund manager, investor, and philanthropist. He established York Capital Management in 1991.

Early life and education

James Dinan was born in 1959 in Baltimore, Maryland to parents Robert and Jeannette Dinan. Raised in a Roman Catholic household alongside four siblings, his family moved to Paxton, Massachusetts in 1969 due to his father's career as a textile engineer. Dinan completed his secondary education at the private Bancroft School in 1977. He then obtained a Bachelor of Science degree in economics from the Wharton School at the University of Pennsylvania in 1981, during which he became a member of the Alpha Chi Rho fraternity. Following graduation, he commenced his professional journey at the stock research firm Donaldson, Lufkin & Jenrette (DLJ). He further advanced his education by earning an M.B.A. from Harvard University in 1985.

Investment career

Dinan began working at Kellner DiLeo & Company, a merger arbitrage firm, in 1985. After experiencing a complete loss of his $600,000 savings during the 1987 stock market crash, he successfully secured $3.6 million from former colleagues at DLJ to launch York Capital in 1991, a hedge fund named after York Avenue where he resided. By 1993, the fund achieved a return of 33.8% and expanded its assets under management to exceed $610 million by the year 2000. In 2010, Dinan sold a one-third interest in York Capital to Credit Suisse for $425 million. The following year, he contributed $1 million to the Museum of the City of New York. By mid-2014, he acquired part ownership of the NBA team Milwaukee Bucks. In June 2017, Dinan designated two successors to oversee leadership at York Capital. As reported in 2018, the firm managed assets totaling $20.5 billion.

Philanthropy

In recognition of a substantial gift made in 2024 to his alma mater, the University of Pennsylvania renamed Henry T. Vance Hall on the Wharton Business School campus as Dinan Hall.

Personal life

James Dinan is married to Elizabeth R. Miller and they have three children, one of whom is racing driver Michael Dinan. The family resides in Manhattan and owns additional residences located in Westchester County, Nantucket, West Palm Beach, and Saint Barthélemy.
