Lewis F. Powell, Jr., American lawyer and jurist (d. 1998)

Lewis Franklin Powell Jr. (September 19, 1907 – August 25, 1998) was an American lawyer and jurist who served as an Associate Justice of the Supreme Court of the United States from 1971 to 1987.

Born in Suffolk, Virginia, he graduated from both Washington and Lee Law School and Harvard Law School and served in the United States Army Air Forces during World War II. He worked for Hunton & Williams, a large law firm in Richmond, Virginia, focusing on corporate law and representing clients such as the Tobacco Institute. In 1971, President Richard Nixon appointed Powell to succeed Associate Justice Hugo Black. He retired from the Court during the administration of President Ronald Reagan, and was eventually succeeded by Anthony Kennedy.

His tenure largely overlapped with that of Chief Justice Warren Burger, and Powell was often a key swing vote on the Burger Court. His majority opinions include First National Bank of Boston v. Bellotti and McCleskey v. Kemp, and he wrote an influential opinion in Regents of the University of California v. Bakke. He notably joined the majority in cases such as United States v. Nixon, Roe v. Wade, Plyler v. Doe, and Bowers v. Hardwick.
