William Joseph Brennan Jr. was a highly influential American jurist. He served as an Associate Justice of the Supreme Court of the United States. His tenure lasted from 1956 until his retirement in 1990. Brennan was known as a leader of the Court's liberal wing. This means he often supported progressive legal ideas. He was the eighth-longest serving justice in the history of the Supreme Court. 
Brennan's career followed a path of increasing legal responsibility. He began by studying economics at the University of Pennsylvania. He then attended Harvard Law School and graduated near the top of his class in 1931. After law school, he worked in private practice in New Jersey. He also served in the U.S. Army during World War II. He rose to the rank of colonel and earned the Legion of Merit Award. Before joining the highest court, he served on the Supreme Court of New Jersey. 
His appointment to the U.S. Supreme Court involved complex political steps. President Dwight D. Eisenhower gave him a recess appointment in October 1956. A recess appointment happens when the President fills a vacancy while the Senate is not in session. Eisenhower chose Brennan because he met three specific criteria. He wanted a candidate with experience on lower courts. He also wanted someone of relative youth and good health. Finally, he wanted a Roman Catholic candidate. Brennan won Senate confirmation in 1957 despite some political controversy. 
On the Supreme Court, Brennan was a master of judicial influence. He was famous for his ability to shape many different opinions. He often bargained with other justices to win their votes. This skill helped him lead the Court during the Warren Era. Chief Justice Earl Warren often asked Brennan to write the majority opinions. Because of this close relationship, other justices nicknamed him the "deputy Chief." He wrote 1,360 opinions during his time on the bench. This is the second-highest number of opinions written by any justice. 
Brennan authored several landmark legal opinions that changed American law. In Baker v. Carr (1962), he established rules for how legislative districts are drawn. In New York Times Co. v. Sullivan (1964), he protected free speech by creating the "actual malice" standard for libel suits. He also helped expand rights for individuals in other ways. In Eisenstadt v. Baird (1972), he helped establish a legal right to contraception for unmarried people. In Craig v. Boren (1976), he ruled that laws discriminating based on sex must face "heightened scrutiny." This means the law must have a very strong reason to treat people differently based on sex.
As the Court became more conservative, Brennan's role changed. During the Burger and Rehnquist Courts, he often found himself in the minority. He was a staunch opponent of the death penalty. He believed it violated the Eighth Amendment's ban on "cruel and unusual" punishment. Brennan wrote a dissenting opinion against the death penalty in more than 1,400 cases. He often worked closely with Justice Thurgood Marshall during these years. Together, they were sometimes called the "Justice Brennan-Marshall" duo by their law clerks. 
Brennan's legal legacy connects to many modern ideas about rights and power. He worked to expand the ability of people to sue for violations of their rights. Through cases like Bivens v. Six Unknown Named Agents, he allowed people to seek damages for Fourth Amendment violations. He also worked on the concept of personal jurisdiction. This is the legal authority of a court to make decisions over a person or a business. In Burger King v. Rudzewicz, his opinion helped expand the reach of state courts over large corporations. His life of service ended with his retirement in 1990.
