An international journey in science and service: Margaret Sena Akpo - American Association for the Advancement of Science (AAAS)

Margaret Hamilton, the computer pioneer whose software powered the first moon landing, has died, the Massachusetts Institute of Technology (MIT) announced on Wednesday. She was 90. In an era before titles such as software engineer and computer scientist became mainstream, Hamilton, who died on 30 September, learned to program under the tutelage of a renowned MIT meteorologist. She continued to perfect the craft in an MIT laboratory, writing software that could detect enemy aircraft. When the institute received a Nasa contract to develop the Apollo onboard flight software, she jumped at the opportunity. “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, minutes before the Apollo 11 spacecraft was set to make history by landing on the lunar surface, an onboard computer’s alarm rang, indicating an emergency. Faced with a decision of whether to abort the mission, the spacecraft continued on. The software was working just as Hamilton and her team intended.
