So she not only co-scripted (with William freaking Faulkner!) the Bogart-Bacall flick which is on most lists of best private eye movies, but then went on to write Rio Bravo, and just before she died she wrote the first draft of The Empire Strikes Back. So she made history in the mystery, western and science fiction genres.
In between she found time to write episodes of The Alfred Hitchcock Hour and The Rockford Files, not to mention Robert Altman's take on Chandler, The Long Goodbye.
There's an old saying that a woman has to be twice as good as a man to succeed in the same job. Imagine being a female script writer in the forties. Wow.
