Thirty-sixth president of the United States, Lyndon B. Johnson, was born on a hill country farm near Stonewall, Texas, on August 27, 1908, to Samuel Ealy Johnson, a former Texas legislator, and Rebekah Baines Johnson. He attended Southwest Teachers College, now Texas State University, graduating with a degree in history and social science in 1930. LBJ spent one year as principal and teacher in Cotulla, educating impoverished Hispanic elementary school students. He became the secretary to Texas Congressman Richard M. Kleberg in 1931; the four-year position helped him gain influential contacts in Washington. Johnson married Claudia Alta "Lady Bird" Taylor on November 17, 1934. LBJ acted as Director of the National Youth Administration in Texas from 1935 to 1937. Johnson won his first legislative election in 1937 for the 10th Congressional District, a position he held for 11 years. He was a firm supporter of President Roosevelt's New Deal and in 1940 acted as Chairman of the Democratic Campaign Committee. In 1948, following his service as a Lieutenant Naval Commander during World War II, LBJ ran as the Democratic nominee for Senate. In a cloud of controversy, he narrowly defeated former Texas Governor Coke Stevens and easily beat his Republican opponent in the general election. Before winning his second Senate term, LBJ was elected Majority Whip in 1951, became the youngest ever Minority Senate Leader in 1953, and was voted Majority Leader in 1954. Johnson unsuccessfully ran for the Democratic presidential nomination in 1960 but was selected to be Vice President under John F. Kennedy.  Johnson was sworn in as Commander and Chief aboard Air Force One following President Kennedy's assassination on November 22, 1963, and won reelection in 1964. As President, he passed landmark legislation with the Civil Rights Act of 1964 and the Voting Rights Act of 1965. Debate over military efforts in Vietnam intensified in late 1963 when the President stated that the United States would not withdraw from Southeast Asia. Escalation of the war against North Vietnam brought disapproval from Democrats, claiming the efforts were misguided, and from Republicans who criticized the administration for not executing sufficient military vigor. Antiwar protests, urban riots, and racial tension eroded Johnson's political base by 1967, which further dissolved following the Tet Offensive in January 1968. On March 31, 1968, Johnson announced that we would not seek a second presidential term. After returning to Texas, Johnson oversaw the construction of the Lyndon Baines Johnson Library and Museum on the University of Texas at Austin campus. Throughout his political career, LBJ was an influential figure in Texas affairs; his policies brought military bases, crop subsidies, government facilities, and federal jobs to the state. After suffering a massive heart attack, Johnson died at his ranch on January 22, 1973. In February of the same year, NASA's Manned Spacecraft Center in Houston was renamed the Lyndon B. Johnson Space Center in honor of one of the country's most influential Texans.
