She was the best. Also the writer/illustrator of "Mike Mulligan and His Steam Shovel," and "Katy and the Big Snow," both of which, like "The Little House," won the Caldecott Medal.
My favorite is her 1962 "Life Story," subtitled "The Story of Life on Our Earth from its Beginning Up to Now," in which the saga of our planet is presented as a sort of play, with each amazing illustration depicted within a proscenium arch. It took her eight years, she claimed, to research this amazing book, which I am very happy to see is still in print.
Yes, I used to read it regularly to my kids as a bedtime story. In fact, all her books were in heavy rotation in my house.
