Jack Valenti, aide to President Lyndon B. Johnson and longtime president of the Motion Picture Association of America, was born in Houston on September 5, 1921. He attended the University of Houston, graduating in 1946 after serving as an Army combat pilot in World War II. Thanks to the GI Bill, Valenti then enrolled at Harvard Business School, earning a MBA in 1948. Upon his return to Houston, Valenti began working for the Humble Oil Company advertising department. He co-founded his own advertising agency in 1952. Conoco, a Humble rival, was its first client.    Valenti first met Lyndon B. Johnson in 1956 at a Houston gathering of young Democrats. When Johnson became John F. Kennedy's running mate, the vice presidential candidate chose Valenti to run the ticket's campaign in Texas. Three years later, Valenti organized the Houston leg of Kennedy's 1963 trip through Texas, joining the presidential motorcade through Dallas on November 22. Following the JFK assassination, Valenti was summoned to Air Force One, where he witnessed Johnson take the oath of office and was hired on the spot as a special assistant. Valenti and his family lived in the White House for the first two months of Johnson's presidency. In 1964, Johnson deputized Valenti to oversee relations between the Oval Office and Congressional Republican leadership.    Valenti resigned from the White House in 1966 to become the president of the Motion Picture Association of America. Holding the post for 38 years, Valenti revolutionized the American film and television industry. In 1968, he created the MPAA film rating system to replace the obsolete Hays Production Code, addressing worries of audience suitability while maintaining a filmmaker's right to free expression. As technology changed and piracy concerns grew, Valenti became a fierce advocate for intellectual property rights, lobbying for the Digital Millennium Copyright Act.    Following his retirement in 2004, Valenti became president of Friends of the Global Fight Against AIDS, Tuberculosis, and Malaria. He died on April 26, 2007, due to complications from a recent stroke. 

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.
