Chief justice of the United States in the context of "Taft family"

The Supreme Court of the United States (SCOTUS) is the highest court in the federal judiciary of the United States. It has ultimate appellate jurisdiction over all U.S. federal court cases, and over state court cases that turn on questions of U.S. constitutional or federal law. It also has original jurisdiction over a narrow range of cases, specifically "all Cases affecting Ambassadors, other public Ministers and Consuls, and those in which a State shall be Party". In 1803, the court asserted itself the power of judicial review, the ability to invalidate a statute for violating a provision of the Constitution. It is also able to strike down presidential directives for violating either the Constitution or statutory law.

Under Article Three of the United States Constitution, the composition and procedures of the Supreme Court were originally established by the 1st Congress through the Judiciary Act of 1789. The court consists of nine justices—the chief justice of the United States and eight associate justices—who meet at the Supreme Court Building in Washington, D.C. Justices have lifetime tenure, meaning they remain on the court until they die, retire, resign, or are impeached and removed from office. When a vacancy occurs, the president, with the advice and consent of the Senate, appoints a new justice.

John Jay (December 23 [O.S. December 12], 1745 – May 17, 1829) was an American statesman, diplomat, signatory of the Treaty of Paris, and a Founding Father of the United States. He served from 1789 to 1795 as the first chief justice of the United States and from 1795 to 1801 as the second governor of New York. Jay directed U.S. foreign policy for much of the 1780s and was an important leader of the Federalist Party after the ratification of the United States Constitution in 1788.

Jay was born into a wealthy family of merchants and New York City government officials of French Huguenot and Dutch descent. He became a lawyer and joined the New York Committee of Correspondence, organizing American opposition to British policies such as the Intolerable Acts in the leadup to the American Revolution. Jay was elected to the First Continental Congress, where he signed the Continental Association, and to the Second Continental Congress, where he served as its president. From 1779 to 1782, Jay served as the ambassador to Spain; he persuaded Spain to provide financial aid to the fledgling United States. He also served as a negotiator of the Treaty of Paris, in which Britain recognized American independence. Following the end of the war, Jay served as Secretary of Foreign Affairs, directing United States foreign policy under the Articles of Confederation government. He also served as the first secretary of state on an interim basis.

Primus inter pares is a Latin phrase meaning first among equals. It is typically used as an honorary title for someone who is formally equal to other members of their group but is accorded unofficial respect, traditionally owing to their seniority in office.

Various modern figures such as the prime minister in parliamentary systems, the president of the Swiss Confederation, the chief justice of the United States, the chief justice of the Philippines, the archbishop of Canterbury of the Anglican Communion, the chair of the Federal Reserve in the United States and the ecumenical patriarch of Constantinople of the Eastern Orthodox Church fall under both senses: bearing higher status and various additional powers while remaining still merely equal to their peers in important senses.

Salmon Portland Chase (January 13, 1808 – May 7, 1873) was an American politician and jurist who served as the sixth chief justice of the United States from 1864 to his death in 1873. He earlier served as the 25th United States secretary of the treasury from 1861 to 1864, during the American Civil War in the Abraham Lincoln administration. Chase also served as the 23rd governor of Ohio from 1856 to 1860, and represented Ohio in the United States Senate from 1849 to 1855 and again in 1861. Chase is therefore one of the few American politicians who have held constitutional office in all three branches of the federal government, in addition to serving in the highest state-level office. From the 1850s onward, even as Chief Justice, Chase sought a presidential nomination that never came because he was considered inept.

Born in Cornish, New Hampshire, Chase studied law under Attorney General William Wirt before establishing a legal practice in Cincinnati. He became an anti-slavery activist and frequently defended fugitive slaves in court. Chase left the Whig Party in 1841 to become the leader of Ohio's Liberty Party. In 1848, he helped establish the Free Soil Party and recruited former President Martin Van Buren to serve as the party's presidential nominee. Chase won election to the Senate the following year, and he opposed the Compromise of 1850 and the Kansas–Nebraska Act. In the aftermath of the Kansas–Nebraska Act, Chase helped establish the Republican Party, which opposed the extension of slavery into the territories. After leaving the Senate, Chase served as the first Republican governor of Ohio from 1856 to 1860.

An associate justice of the Supreme Court of the United States is a justice of the Supreme Court of the United States, other than the chief justice of the United States. The number of associate justices is eight, as set by the Judiciary Act of 1869.

Article II, Section 2, Clause 2 of the Constitution of the United States grants plenary power to the president to nominate, and with the advice and consent (confirmation) of the Senate, appoint justices to the Supreme Court. Article III, Section 1 of the Constitution effectively grants life tenure to associate justices, and all other federal judges, which ends only when a justice dies, retires, resigns, or is impeached and convicted.

John Marshall (September 24, 1755 – July 6, 1835) was an American statesman, jurist, and Founding Father who served as the fourth chief justice of the United States from 1801 until his death in 1835. He remains the longest-serving chief justice and fourth-longest-serving justice in the history of the U.S. Supreme Court, and he is widely regarded as one of the most influential justices ever to serve. Prior to joining the court, Marshall briefly served as both the U.S. Secretary of State under President John Adams and a U.S. Representative from Virginia, making him one of the few Americans to have held a constitutional office in each of the three branches of the United States federal government.

Marshall was born in Germantown in the Colony of Virginia in British America in 1755. After the outbreak of the American Revolutionary War, he joined the Continental Army, serving in numerous battles. During the later stages of the war, he was admitted to the state bar and won election to the Virginia House of Delegates. Marshall favored the ratification of the U.S. Constitution, and he played a major role in Virginia's ratification of that document. At the request of President Adams, Marshall traveled to France in 1797 to help bring an end to attacks on American shipping. In what became known as the XYZ Affair, the government of France refused to open negotiations unless the United States agreed to pay bribes. Upon his return from France, he led the Federalist Party in Congress. He was appointed secretary of state in 1800 after a cabinet shake-up, becoming an important figure in the Adams administration.

William Howard Taft (September 15, 1857 – March 8, 1930) was the 27th president of the United States from 1909 to 1913 and the tenth chief justice of the United States from 1921 to 1930. He is the only person to have held both offices.

Taft was born in Cincinnati, Ohio. His father, Alphonso Taft, was a U.S. attorney general and secretary of war. Taft attended Yale and joined Skull and Bones, of which his father was a founding member. After becoming a lawyer, Taft was appointed a judge while still in his twenties. He continued a rapid rise, being named solicitor general and a judge of the Sixth Circuit Court of Appeals. In 1901, President William McKinley appointed Taft civilian governor of the Philippines. In 1904, President Theodore Roosevelt made him Secretary of War, and he became Roosevelt's hand-picked successor. Despite his personal ambition to become chief justice, Taft declined repeated offers of appointment to the Supreme Court of the United States, believing his political work to be more important.

Oliver Ellsworth (April 29, 1745 – November 26, 1807) was a Founding Father of the United States, attorney, jurist, politician, and diplomat. Ellsworth was a framer of the United States Constitution, United States senator from Connecticut, and the third chief justice of the United States. Additionally, he received 11 electoral votes in the 1796 presidential election.

Born in Windsor, Connecticut, Ellsworth attended the College of New Jersey where he helped found the American Whig–Cliosophic Society. In 1777, he became the state attorney for Hartford County, Connecticut, and was selected as a delegate to the Continental Congress, serving during the remainder of the American Revolutionary War. He served as a state judge during the 1780s and was selected as a delegate to the 1787 Philadelphia Convention, which produced the United States Constitution. While at the convention, Ellsworth played a role in fashioning the Connecticut Compromise between the more populous states and the less populous states. He also served on the Committee of Detail, which prepared the first draft of the Constitution, but he left the convention and did not sign the document.
