Former Judge Ralph K. Winter of the U.S. Court of Appeals for the Second Circuit, a respected Yale Law School professor who served for decades on the Second Circuit, has died following a long illness, Chief Judge Debra Ann Livingston announced late Tuesday. He was 85.

A ranking member of the federal judiciary and protégé of the late U.S. Supreme Court Justice Thurgood Marshall, Winter joined the Manhattan-based appeals court in 1982, after his nomination by President Ronald Reagan the year prior.
