Michael Steinhardt is a prominent hedge fund manager. He formed his own hedge fund management firm, originally known as Steinhardt, Fine, Berkowitz & Co., in 1967, in his mid 20s. It opened an offshore fund in 1970. Over time, as Messrs Fine and Berkowitz went their own ways, this firm evolved into Steinhardt Partners. It was, in essence, an event driven multi-strategy fund.
Steinhardt subsequently retired from the asset-management business and has devoted himself to philanthropy. In his retirement, Steinhardt wrote his autobiography: “No Bull: My Life in and out of Markets.”
