Bernstine taught only one course that I took, Federal Courts, which dealt with the arcana of the Constitutional jurisdiction of the federal courts in the United States. Some 36 years later, I don't remember much of the class but I do remember then-professor Bernstine positively. His class-appropriate yellow tee-shirt emblazoned with an old-fashioned steam engine with the words "Erie Railroad Co." stands out among my law school memories.
Bernstine went on to become the law school's dean and held a variety of other posts over the subsequent years. He was 69 at his death, which means he was only seven years older than me. A sobering thought.
