Lady Bird Johson
1912-2007 I have no idea of her political or social views, I just know one thing about her, and it puts her in the strong, gorgeous category as far as I am concerned - it was her campaign to "Keep America Beautiful" that was part of beginning to teach people that littering wasn't okay.
When I was a child, people thought nothing of opening a pack of gum, and throwing the wrapper on the ground, or throwing empty bottles or containers out their car windows, like it would disappear once it was out of their hands. Lady Bird Johnson played a big part in changing that.
