I've talked a lot about PRIDE, Milt Bryce's information-systems methodology that was perhaps the first commercially available, rigorous methodology for developing software and the first serious attempt to transform information systems development in the commercial sector from an arcane art into a proven, repeatable science. It really has few forbears.

But... Margaret Hamilton was one of those forbears. She got the ideas out there; PRIDE just commercialized them and made them palatable to business IT shops.
