Quick Answer
Margaret Hamilton led the team that wrote the Apollo spacecraft's flight software.
The Full Story
Computer scientist Margaret Hamilton led the MIT Instrumentation Laboratory team that developed the onboard flight software for NASA's Apollo programme. Her software architecture, including priority-driven task scheduling and error recovery, proved critical during the Apollo 11 landing when the computer was overloaded with radar data — it correctly prioritised landing tasks and the mission continued. Hamilton coined the term "software engineering" to legitimise the discipline. She received the Presidential Medal of Freedom in 2016.
Key Facts
1.The Apollo guidance computer had about 72 kilobytes of memory — less than a modern calculator.
2.Hamilton's software detected the overload problem just three minutes before touchdown.
3.She brought her young daughter to the lab at night while debugging code.
