Samuel Taliaferro Rayburn (January 6, 1882 – November 16, 1961) was an American politician who served as the 43rd speaker of the United States House of Representatives. He was a three-time House speaker, former House majority leader, two-time House minority leader, and a 25-term congressman, representing Texas's 4th congressional district as a Democrat from 1913 to 1961. He holds the record for the longest tenure as Speaker of the United States House of Representatives, serving for over 17 years (among his three separate tenures).

Born in Roane County, Tennessee, Rayburn moved with his family to Windom, Texas, in 1887. Sam T. Rayburn graduated from East Texas Normal College, Class of 1903. After a period as a school teacher, Rayburn won election to the Texas House of Representatives and graduated from the University of Texas School of Law. He won election to the United States House of Representatives in 1912 and continuously won re-election until his death in 1961, serving a total of 25 terms. Rayburn was a protégé of John Nance Garner and a mentor to Lyndon B. Johnson.

Rayburn was elected House Majority Leader in 1937 and was elevated to the position of Speaker of the House after the death of William B. Bankhead. He led the House Democrats from 1940 to 1961, and served as Speaker of the House from 1940 to 1947, 1949 to 1953, and 1955 to 1961. Rayburn also served twice as House Minority Leader (1947 to 1949 and 1953 to 1955) during periods of Republican House control. He preferred to work quietly in the background and successfully used his power of persuasion and charisma to get his bills passed due to having to navigate the post-Joseph Cannon era when each individual committee chairman had immense power in the House.

Along with Senate Majority Leader Lyndon Johnson and most of the Texan Representatives, Rayburn refused to sign the 1956 Southern Manifesto and helped shepherd the passage of the Civil Rights Acts of 1957 and 1960, the first civil rights bills passed by the U.S. Congress since the Enforcement Acts and the Civil Rights Act of 1875 during Reconstruction (1865–1877). Rayburn was also influential in the construction of U.S. Route 66. He served as Speaker until his death in 1961, and was succeeded by John W. McCormack. He is the most recent Speaker of the House to die in office.

Early life Rayburn was born in Roane County, Tennessee, on January 6, 1882. He was the son of Martha Clementine (Waller) and William Marion Rayburn, a former Confederate cavalryman. The Rayburn family descended from Ulster Scots immigrants who emigrated to the Province of Pennsylvania in 1750. In 1887, the Rayburn family moved to a 40-acre cotton farm near Windom, Texas. Rayburn grew up in poverty as he, his nine siblings, and his parents all participated in running the farm. Toiling in the fields made Rayburn determined to get a good education and help the poor and downtrodden.

Rayburn went to co-educational East Texas Normal College (now East Texas A&M University) in Commerce, Texas, in 1900 with $25 (around $750 in 2020) that his father saved up to help take care of his first few months of college expenses. To help cover tuition and room and board, Rayburn rang the school bell to signal the end of classes and swept out Commerce's public school buildings, earning $3 a month. Rayburn obtained his teaching credentials before completing his bachelor of science degree, and earned additional income by teaching in the public school of Greenwood, a small community in Hopkins County. He graduated in 1903 in a class of 13 (9 men and 4 women) and taught school for two years.

Texas State Legislature In 1906, at the age of 24, Rayburn won by a narrow 163 vote margin an election to the 34th district of the Texas House of Representatives. While serving in the legislature, he studied at the University of Texas School of Law, and he was admitted to the bar in 1908. As a representative, Rayburn helped pass laws that made textbooks more widely available to Texas schoolchildren, established the State Board of Health alongside the Texas State Department of Health, and created the Texas Department of Agriculture. Due to his power of persuasion when he was a very young legislator for four years on January 10, 1911, at 29 years of age, Rayburn became the youngest Speaker of the Texas House of Representatives in history. He defeated Clarence E. Gilmore 70 to 63 in the speaker election. Texas speakers from the beginning of statehood until Rayburn's tenure were mostly ceremonial and powerless, similar to the president pro tempore of the U.S. Senate. Under Texas state law the office actually had immense powers but the previous speakers never exercised them due to deference to party bosses. Upon election as Speaker, Rayburn requested the appointment of a special committee to determine "the duties and rights of the speaker". This became the first ever codification of the speaker's power. He helped pass much legislation as Speaker, including shorter working hours for women, child labor laws, and appropriations for a Confederate widows’ home and a tuberculosis sanitarium. Many decades later Rayburn rated his service as Texas House Speaker as the most enjoyable period in his long political career. He said, "that job had real power—that's what a man wants—but power's no good unless you have the guts to use it."

U.S. House of Representatives Due to a series of lucky events for Rayburn, the House district of his home county of Fannin County, the fourth district, was open for him to run. Senator Joseph Weldon Bailey was rocked by allegations of corruption and bribery involving oil companies so he announced his resignation effective January 1913. The longtime incumbent representative of the fourth district, Choice B. Randell, ran for Bailey's open senate seat in the July 1912 primary election and lost. Rayburn won election to the House of Representatives in 1912 after a bruising Democratic primary where he won by only 490 votes. He won the general election afterwards and became a Representative. He entered Congress in 1913 at the beginning of Woodrow Wilson's presidency and served in office for almost 49 years (more than 24 terms), until the beginning of John F. Kennedy's presidency.

Rayburn was a protégé of then-Representative John Nance Garner. Despite Rayburn's freshman status, in 1913, Garner helped him become a member of the powerful House Interstate and Foreign Commerce Committee, which handled legislation pertaining to commerce, bridges, coal, oil, communication, motion pictures, securities exchanges, holding companies and the Coast Guard. Rayburn learned how to make deals and how to deal with adversity during his first two decades in the House. While he was a young representative he introduced and helped pass numerous anti-trust and railroad-related legislation such as the Clayton Antitrust Act of 1914, the Federal Trade Commission Act of 1914 and the Esch–Cummins Transportation Act (The Railway Stock and Bond Bill that was originally introduced in 1914 was the first ever major legislation that was crafted and proposed by Rayburn. In 1920 it finally became law in the Esch-Cummins Act).

As a signal of things to come for Rayburn, after only eight years in the House he was elected to be House Democratic Caucus Chairman. He served as chairman from 1921 to 1923. At only age 39 when he was elected chairman he was the youngest person ever elected to that position. During the 1920s, Rayburn kept a low profile due to the Republican dominance of Congress and the Presidency under Presidents Harding, Coolidge, and Hoover. Rayburn's biggest contribution in this decade was to help create the U.S. Highway System in 1926, the first major victory of his lifelong dream to make paved roads available for all Americans.

Rayburn worked as Garner's campaign manager during the 1932 presidential election and released Garner's delegates to vote for Roosevelt after a deal was made to make Garner the vice-presidential nominee.

From 1931 to 1937, Rayburn was Chairman of the House Interstate and Foreign Commerce Committee. Due to his position and influence on this committee he helped pass landmark New Deal bills such as the Truth in Securities Act, the bills that established the Securities and Exchange Commission and the Federal Communications Commission, the Public Utilities Holding Company Act, the Emergency Railroad Transportation Act, and the Rural Electrification Act.

Rayburn was a big supporter of projects that helped make life easier for farmers and rural Americans like dams and farm-to-market roads. His role in creating new lakes such as Lake Texoma and changing old rural dirt roads into fully paved roads ensured lifelong support from his congressional district constituents. The dams in rural America controlled rivers from flooding and also generated electricity. The Flood Control Act of 1936 combined with the Rural Electrification Act helped to bring electricity to 90% of rural America by 1959, compared to only 3% in the early 1930s. In 1943–44, Rayburn helped to establish in Texas, Oklahoma, Arkansas, Missouri, Kansas, and Louisiana the Southwestern Power Administration, which became a "mini-Tennessee Valley Authority" in the region. The main difference from the TVA was the SWPA only involved federal dams constructed by the U.S. Army Corps of Engineers. He also helped pass laws that established the Soil Conservation Service and the Civilian Conservation Corps. These two agencies were primarily engaged in water and soil erosion control due to the negative effects of farming in America that led to catastrophes like the Dust Bowl.

Speaker of the House

On September 16, 1940, at the age of 58, and while serving as House Majority Leader, Rayburn became Speaker of the House upon the sudden death of Speaker William Bankhead. Rayburn's ascension to the speakership was surprisingly rapid; that including Bankhead, the three Speakers prior to Rayburn died in office within six years. (Henry Thomas Rainey died in 1934 and Jo Byrns in 1936.)

Rayburn's first major crisis after assuming the speakership was World War II. In the decade prior to the war, the United States was isolationist and decided not to participate in the war when war broke out in 1937 in Asia and 1939 in Europe. Rayburn helped pass the Lend-Lease Act in March 1941. This act allowed the U.S. to distribute food, oil, and materiel to the United Kingdom, China, and the Soviet Union. In August 1941, he helped pass the Service Extension Act of 1941. In 1940, a 12-month peacetime draft was instituted by the government to prepare for possible war. But the isolationists in the House wanted to not get involved in the war and wanted to let the peacetime draft expire after 12 months in 1941. After Rayburn talked to all representatives who were anti-draft and tried to persuade them to change their minds, the bill was passed by a vote of 203–202, a one-vote margin. If this bill had been defeated, the U.S. Army stood to lose about two-thirds of its strength and three-fourths of the officer corps due to the end of the draft.

In early 1944, top Roosevelt officials approached Rayburn and asked him to work discreetly with Congress to gain funding for the production of an atomic bomb. Later that year, Rayburn secured $1.6 billion to fund the Manhattan Project, the code name for the secret project that led to the creation of the atomic bomb. This secret operation was done with most of the President's own cabinet, all of Congress save for a few members, and even the vice president not knowing about the atomic bomb. Only Rayburn, the Senate Majority Leader, and five other congressmen were aware of this operation. Rayburn had to hide the Manhattan Project through fake names and other deceptive means in appropriation bills until the bombs were used in 1945.
