As chief justice of the United States, William Hubbs Rehnquist oversaw the Court’s profound shift in a conservative direction after the more liberal leadership of his predecessor, Warren Burger. Rehnquist was born on October 1, 1924, in Milwaukee, Wisconsin. After serving in the U.S. Army Air Forces from 1943 to 1946, he attended Stanford University in California, earning bachelor’s and master’s degrees in political science. After two years at Harvard University, where he earned a second master’s degree in government in 1950, he returned to Stanford to attend law school. There he graduated first in his class in 1952; one of his classmates was his future Supreme Court colleague Sandra Day O’Connor.
