There is a very nice oral history the Computer History Museum produced: https://computerhistory.org/blog/margaret-hamilton-in-her-ow...
In Levy's "Hackers" there is a story about late night hacking on the TX-0 that fouled-up some weather simulation code an academic user of the computer was running. After hearing this oral history I believe Margaret was the programmer and the code was for Prof. Edward Lorenz.
