Lady Bird Johnson was born Claudia Alta Taylor in nineteen twelve. The Taylor family lived in the small town of Karnack, Texas. Claudia's father, Thomas Jefferson Taylor, owned two stores as well as thousands of hectares（公顷） for cotton production. Her mother, Minnie Taylor, died when Claudia was only five years old. A woman who worked for the Taylor family gave Claudia her nickname. Alice Tittle said the small child was "as purty as a lady bird."
As first lady, Missus Johnson became an energetic activist for educational and environmental issues. She helped support Head Start, a public program aimed at giving educational and health services to young children from poor families.
She started the Society for a More Beautiful National Capitol. Its aim was to improve the beauty of Washington by planting trees and flowers in public areas and parks. Missus Johnson understood that these improvements were also linked to important issues such as pollution, public transportation, mental health, and crime rates.
Lyndon Johnson and Lady Bird Johnson had a difficult four-year term. The president faced strong opposition about the United States involvement in the war in Vietnam.

Mister Johnson died of a heart attack in nineteen seventy-three.
Lady Bird Johnson continued her tireless work to improve the country's natural environment. She created the National Wildflower Research Center in nineteen eighty-two.
