Margaret Hamilton, scientist who worked on NASA’s Apollo program, dead at 90

American computer scientist Margaret Hamilton, who played a pivotal role in developing the software for NASA's Apollo lunar program, has passed away at the age of 90, according to her former employer, the Massachusetts Institute of Technology (MIT). MIT described Hamilton as a "computing pioneer" and noted that she passed away on September 30.

Olivier de Weck, the Apollo Program Professor and interim head of MIT's Department of Aeronautics and Astronautics, hailed Hamilton as a visionary who was "ahead of her time." De Weck highlighted her groundbreaking work in software engineering during the nascent stages of the field, emphasizing that she not only developed advanced code herself but also led a team in utilizing this cutting-edge technology to create one of humanity's most complex systems.

Hamilton's contributions were instrumental in the successful Apollo program, which enabled the United States to achieve the historic feat of landing humans on the Moon, thereby surpassing the Soviet Union in the space race. Born in Indiana in 1936, Hamilton pursued mathematics before relocating to Boston, Massachusetts in 1959. She began her career at MIT in meteorology before joining a lab in 1965 that sought to develop software for the ambitious Apollo project.

Hamilton was the first programmer for the Apollo program at MIT and later became the assistant director in charge of the Apollo Command and Service Module team. Her software played a critical role in ensuring the onboard systems were robust and resilient, intervening just moments before the Eagle lander of the Apollo 11 mission touched down on the Moon, overriding a faulty script and guaranteeing the mission's safety.

James Wohletz, CEO of the Draper Laboratory, which was formed from MIT's Instrumentation Lab, praised Hamilton for her lasting impact on the organization. He credited her leadership and contributions to the Apollo Guidance Computer's onboard flight software, which ensured the safe landing and return of Apollo astronauts. In 2016, Hamilton received the prestigious Presidential Medal of Freedom from former President Barack Obama for her remarkable achievements.

In a 2009 interview with MIT News, Hamilton reflected on the challenges and triumphs of her early career, emphasizing the importance of dedication, mutual respect, and the freedom given to the team to innovate and push boundaries. She expressed a sense of pride in being among the pioneers who ventured into the uncharted territory of software development, acknowledging that their work was a testament to their commitment and the trust placed in them by upper management.

Hamilton continued to contribute to the field by publishing over 130 papers and founding two successful software companies, Higher Order Software and Hamilton Technologies, after her illustrious career at MIT.
