Lady Bird Johnson, the former first lady who championed conservation and worked tenaciously for the political career of her husband, former President Lyndon B. Johnson, died Wednesday, a family spokeswoman said. She was 94.
Lady Bird Johnson returned home late last month after a week at Seton Medical Center, where she'd been admitted for a low-grade fever. Her husband died in 1973.
She died at her Austin, Texas, home of natural causes about 4:18 pm local time. Elizabeth Christian, the spokeswoman, said she was surrounded by family and friends.
She was hospitalized with a stroke in 2002 that left her with difficulty speaking. But even after that she continued to make public appearances and in May attended an event at the LBJ Library and Museum featuring historian Robert Dallek.
In March, she listened from Texas through a conference call when President Bush signed legislation naming the Education Department headquarters building in Washington, D.C., after her late husband.
