Earl Warren was born on March 19, 1891, in Los Angeles, California. He was educated at the University of California in 1912 and received a degree in law in 1914. He became Deputy City Attorney of Oakland in 1919 and held three terms as district attorney of Alameda County starting in 1925. Warren was elected attorney general of California in 1938 and elected governor of California in 1942. He was twice reelected to governor in 1946 and 1950. He lost an election in 1948 when running for the Republican vice president with Thomas E. Dewey running for president.
On March 1, 1953, Warren was appointed by Dwight D. Eisenhower as fourteenth chief justice of the U.S. Supreme Court. During his stay, the liberal court was known as the "Warren Court." He retired in 1969 and became known for his rulings in many landmark cases. In Brown v. Board, he established the ruling that "separate educational facilities are inherently unequal." This ruling overturned the previous ruling in Plessy v. Ferguson. In Miranda v. Arizona, the court said criminals must be informed of their rights at the time of their arrests.
Warren headed the commision investigating the assassination of John F. Kennedy in 1963 and later died on July 9, 1974 in Washington, D.C.
