Margaret Hamilton, a pioneer in computer science whose work helped land astronauts on the Moon, died at the age of 90.
Hamilton led the team at MIT that created the software which guided Apollo 11’s descent and landing on 20 July 1969. The program was designed to keep the mission safe even when the onboard computer was overloaded, a feature that proved critical during the historic launch.
Known for coining the expression “software engineering,” Hamilton’s career began at MIT in 1959 and extended into the 1970s. After leaving the institute, she founded several software companies, including Hamilton Technologies, which continues to operate today.
In 2016 Barack Obama awarded her the Presidential Medal of Freedom, recognizing her as an emblem of the unsung women who shaped space exploration.
Hamilton was born in Indiana in 1936 and earned a B.A. in mathematics from Earlham College in 1958. She moved to Boston a year later with her husband, initially taking a position at MIT to support his legal studies. Imperial to her life's work, MIT confirmed her death on 30 September and remembered her as “ahead of her time” and a true trailblazer in computing.
She is survived by her daughter, son‑in‑law, two grandsons and four great‑grandchildren, according to MIT.
