His death Wednesday at the Federal Medical Center in the prison in Butner, North Carolina, was confirmed by the US Bureau of Prisons. A cause of death was not released.
In February 2020, he petitioned the courts for an early release from prison, stating that he had terminal kidney failure and a life expectancy of less than 18 months. But the US Attorney's office for the southern district of New York said Madoff's crime was "unprecedented in scope and magnitude" and is "sufficient reason" to deny Madoff's request.
Madoff was the mastermind behind a $20 billion Ponzi scheme -- the largest financial fraud in history.
He had a legendary career on Wall Street, famously delivering astronomical returns for his investors, which included director Steven Spielberg, actors Kevin Bacon and Kyra Sedgwick and New York Mets owner Fred Wilpon.
