Julian Hart Robertson Jr. (1932-2022) was an American billionaire investor and hedge fund manager, widely regarded as one of the pioneers of the hedge fund industry. He was the founder of Tiger Management Corporation, which he started in 1980 with $8 million in initial capital and grew into one of the world's largest and most successful hedge funds, peaking at over $22 billion in assets by 2000. Known for its rigorous research-driven approach and long-short equity strategies, Robertson mentored a generation of investors through his 'Tiger Cubs'—former employees who founded prominent funds like Viking Global, Tiger Global Management, and Baupost Group. After closing Tiger Management to outside investors in 2000, he continued managing his personal fortune and became a prominent philanthropist through the Robertson Foundation, focusing on education initiatives, medical research, and conservation. His notable philanthropic contributions included support for charter schools like Success Academy, over $100 million to Lincoln Center for the Performing Arts, and significant donations to Memorial Sloan Kettering Cancer Center and environmental causes. Robertson passed away in 2022 at age 90, leaving a legacy as a titan of finance and philanthropy.
