Claudia Alta Taylor was born on Dec. 22, 1912, and her nursemaid quickly declared her as “pretty as a ladybird” — giving her a nickname for life. Born in Karnack, the future Mrs. Johnson would become “an author, a businesswoman, a champion of education and conservation efforts,” according to her American-Statesman obituary.

That obituary, written by Janet Wilson, begins:

Her marriage to a larger-than-life Texan thrust a shy, small-town girl named Lady Bird Johnson into the national spotlight. A love affair with the great outdoors kept her there.

And though nationally, she was best known as the wife of Lyndon B. Johnson, the 36th president, Mrs. Johnson was very much a figure in her own right. She mixed Southern graciousness with a quiet, cast-iron fortitude that not only won admirers but allowed her to steer a large business enterprise and help forge a national environmental movement.

Here’s a look back in photos at a little of her remarkable life:
