Margaret Hamilton, a computer scientist who led the software development for NASA's Apollo missions and played a crucial role in safely landing astronauts on the Moon, died at age 90 on September 30. At MIT from 1959 until the mid-1970s, she managed the Software Engineering Division, which developed all onboard flight software for Apollo 11. Notably, her team's priority-driven software averted critical errors during the Moon landing in 1969. In recognition of her contributions to science and space travel, President Barack Obama awarded Hamilton the Presidential Medal of Freedom in 2016.

Story summary
Margaret Hamilton, a pioneering computer scientist whose software played a critical role in NASA's Apollo 11 moon landing, died at age 90 on September 30, 2022. Born in Indiana and educated at the University of Michigan and Earlham College where she earned her BA in mathematics in 1958, Hamilton joined MIT in 1959 as a programmer before software engineering was widely recognized. She led the team that developed onboard flight software for NASA’s Apollo missions, becoming the first woman hired for such a position at MIT.
During the Apollo 11 mission, when alarms indicated potential computer issues prior to landing, Hamilton's software successfully diagnosed and prioritized essential tasks, ensuring Neil Armstrong and Buzz Aldrin could safely touch down on the Moon. Her work revolutionized software engineering practices in space exploration and inspired future generations of scientists and engineers.

The computer scientist behind groundbreaking research that helped land Nasa's astronauts on the Moon, has died aged 90.

Margaret Hamilton was a trailblazer in her field, leading the team who developed the software for Nasa's Apollo missions, which coined the term "software engineering".
Hamilton's former employer, the Massachusetts Institute of Technology (MIT), confirmed her death, adding she died on 30 September.

"To say Hamilton was a pioneer - to say she was ahead of her time - would be a dramatic understatement," MIT said in its statement, before acknowledging that she was a software engineer before it was mainstream.

Hamilton worked at MIT from 1959 until the mid-1970s and managed the Software Engineering Division.

It was in this division that she led a team of engineers writing and testing all on-board in-flight software for Nasa's Apollo 11 project that guided US astronauts Neil Armstrong and Buzz Aldrin to land safely on the Moon.
"I was attracted both by the sheer idea and the fact that it had never been done before.

I was the first programmer to join and the first woman they hired," she told the Guardian in 2019.

In 1969, moments before the historic Apollo 11 Moon landing, an onboard computer raised an alarm, signalling an error was occurring.
asserted
error → raise → alarm
The error detected the computer was overloaded, and for a moment it looked like the complex landing might not be achieved.
uncertain
landing → detect → moment
But Hamilton and her team had planned for such an error by engineering "priority-driven software" to shut down any background tasks and favour the most important - the Moon landing - according to MIT.

In 2016, Hamilton's life work was honoured by Barack Obama with the Presidential Medal of Freedom for her contribution to science and space travel.

Hamilton, born in Indiana in 1936, first studied mathematics at the University of Michigan in 1955 before moving to Earlham College where she got a BA in mathematics in 1958.
"We are saddened by her death, but grateful for the opportunity to have celebrated her extraordinary achievements throughout her long life", Earlham College said in a statement on social media.
"Her pioneering spirit and remarkable legacy will continue to inspire generations of Earlhamites," the statement said.

Hamilton is survived by her daughter, a son-in-law, two grandsons and four great-grandchildren, according to MIT.
