Born into a farm family, he graduated (1930) from Southwest Texas State Teachers College (now Southwest Texas State Univ.), in San Marcos. He taught in a Houston high school before becoming (1932) secretary to a Texas Congressman. In 1934 he married Claudia Alta Taylor (see Lady Bird Johnson), and they had two daughters, Lynda Bird and Luci Baines. A staunch New Dealer, Johnson gained the friendship of the influential Sam Rayburn, at whose behest President Franklin D. Roosevelt made him (1935) director in Texas of the National Youth Administration.
