Margaret Hamilton, NASA software engineering pioneer, dies at 90

Margaret Hamilton, the pioneering computer scientist and systems engineer known for her critical role in NASA’s Apollo program, has passed away at the age of 90.

As the director of the Software Engineering Division at the MIT Instrumentation Laboratory, Hamilton led the development of the on-board navigation software that enabled the Apollo 11 moon landing. Her design principles allowed the flight computer to manage critical overloads, ensuring the safety of the astronauts during the mission.

Hamilton is widely credited with coining the term ‘software engineering,’ a move that established the field as a rigorous academic and professional discipline on par with hardware engineering. Beyond her work with NASA, she founded Hamilton Technologies, Inc., where she developed the Universal Systems Language and the ‘Development Before the Fact’ mathematical theory for ultra-reliable systems design. Her achievements were recognized globally, including receiving the Presidential Medal of Freedom from Barack Obama in 2016 and an honorary doctorate from the Universitat Politècnica de Catalunya.
