Norman Redlich, former dean of New York University School of Law and Corporation Counsel for the City of New York, died Friday at his Manhattan home following complications of Parkinson’s disease. He was 85.

The Bronx-born Mr. Redlich worked for his family’s business for several years after graduating from Yale Law School in 1950. He received an LL.M in taxation from New York University Law School in 1955 and joined the school’s faculty in 1960. In 1963 and 1964, he served as the assistant counsel of the Warren Commission investigating President Kennedy’s assassination.
