Laura Ingalls Wilder
It makes sense to us that Wilder would have started rather late — after all, if her Little House on the Prairie books are as autobiographical as they say, the lady had a lot of living to get through before she could put it all to paper. She actually began writing around age 44, working as a columnist, and had a pretty successful freelance career. But it wasn’t until 1931, when she published Little House in the Big Woods, that Wilder really made a name for herself, both in contemporary circles and for decades to come. She was 64.
