Walter F. Murphy, an esteemed constitutional scholar and Charleston native, died Tuesday. He was 80.

Born in Charleston in 1929, Murphy traveled the country, earning advanced degrees in political science. While Murphy's studies and career kept him from the Lowcountry, he returned to Charleston in 2009.

Murphy's first wife, Mary T. Dolan Murphy, died in 2006. They had two daughters. In early 2010, Murphy married his first girlfriend, Doris Maher Murphy of Ravenel.

Murphy taught at Princeton University in New Jersey for 37 years, advising now well-know students, including U.S. Supreme Court Justice Samuel Alito.

Murphy served as the McCormick Professor of Jurisprudence at Princeton, a chair first held by Woodrow Wilson. In 2001, the annual Walter Murphy Lecture in American Constitutionalism was established in his honor, as Murphy is credited with pioneering the study of judicial politics within the Supreme Court.

During his studies, Murphy served in the U.S. Marine Corps, receiving a Distinguished Service Cross, Purple Heart and a Presidential Unit Citation for his efforts in Korea. Murphy retired from the Corps in 1974 as a colonel.

A memorial service will be held on Princeton's campus at a later date.
