Gerald Gunther (May 26, 1927 – July 30, 2002) was a German born American constitutional law scholar and a Professor of Law at Stanford Law School from 1962 until his death in 2002. Gunther was among the twenty most widely cited legal scholars of the 20th century, and his 1972 Harvard Law Review article, "The Supreme Court, 1971 Term Foreword: In Search of Evolving Doctrine on a Changing Court: A Model for a Newer Equal Protection," is the fourth most-cited law review article of all time. Gunther's pathbreaking casebook, Constitutional Law, originally published in 1965 and now in its 17th edition (co-edited with Kathleen Sullivan), is the most widely used constitutional law textbook in American law schools.
