Margaret Hamilton, a groundbreaking computer scientist who led the team that created the onboard flight software for NASA’s moon-bound Apollo program and later in life was celebrated as a powerful symbol of women in technology, has died. 30 at a hospital in Cambridge, Massachusetts, her daughter, Lauren Hamilton, told The Associated Press on Thursday. NASA Administrator Jared Isaacman said on the social platform X that her work helped make humanity’s first journeys to the moon possible.

“To say Margaret Hamilton was a pioneer — to say she was ahead of her time — would be a dramatic understatement,” Olivier de Weck, the Apollo program professor at MIT and interim head of its aeronautics and astronautics department, told MIT News, a publication of the university’s communications office. “She was a software engineer at a time when that field was in its infancy,” de Weck continued, “and she not only developed advanced code herself but also led a team in using that nascent technology to develop one of the most complex systems humanity had ever achieved.” In recent years a photo circulated online showing a smiling Hamilton, in her early 30s, standing next to a towering stack of pages containing codes her team used during the Apollo project. And a Lego set celebrating the women of NASA that was unveiled in 2017 included a figure of Hamilton.

She graduated with a degree in mathematics from Earlham College in Richmond, Indiana, in 1958 and went to work for MIT in 1959. Her early focus there included working with a meteorology professor on weather prediction software, according to the MIT News article. In the mid-1960s, she started at MIT’s Instrumentation Lab, which had a NASA contract for Apollo.

After first working on software for uncrewed missions, she later led the team developing the onboard flight software for the crewed missions, and by 1968 she was assistant director in charge of the command and service module team, according to MIT News. “We took our work seriously, many of us beginning this journey while still in our 20s,” Hamilton told MIT News in 2009. “Coming up with solutions and new ideas was an adventure.” “Because software was a mystery, a black box, upper management gave us total freedom and trust,” she continued.

Looking back, we were the luckiest people in the world; there was no … Looking back, we were the luckiest people in the world; there was no choice b… Margaret Hamilton, who coined the term "software engineering" and led the development of on-board flight software for NASA's Apollo program in the 1960s, died last week at the age of 90.

A recipient of the Presidential Medal of Freedom in 2016, Hamilton was also immortalized as a LEGO minifig the following year—part of the "Women of NASA" set that also included astronauts Mae Jemison and Sally Ride. She was a software engineer at a time when that field was in its infancy, and she not only developed advanced code herself but also led a team in using that nascent technology to develop one of the most complex systems humanity had ever achieved,” said Olivier de Weck, interim head of the MIT Department of Aeronautics and Astronautics. “The Apollo program still stands as one of our greatest testaments to the power of collaboration, ingenuity, and engineering, and Hamilton was a fundamental contributor to that program’s success.” Born in 1936 in Paoli, Indiana, Hamilton graduated from Earlham College in 1958 with a degree in mathematics and a minor in philosophy—the latter a nod to her father (a poet) and grandfather (a headmaster).
