Quick Summary

Margaret Hamilton, who created the software that powered NASA’s Apollo 11 moon landing and pioneered computer programming in an era before it became common, passed away at age 90 on September 30. At MIT, she learned to program under a meteorologist and later developed error detection and recovery mechanisms for the Apollo mission's onboard flight system, which successfully handled critical hardware issues during the historic lunar landing in 1969. President Obama highlighted her contributions when he awarded her the Presidential Medal of Freedom in 2016.

Story summary

Margaret Hamilton, a pioneering computer scientist who developed critical software for NASA's Apollo program, died at age 90 on September 30. Born in Indiana in 1936, she studied mathematics and later joined MIT where she became the first programmer hired by NASA for the Apollo project in 1965. Her work was crucial during the historic moon landing of Apollo 11 in 1969, particularly when her software successfully managed hardware issues, ensuring the mission's success. Hamilton’s contributions made her a symbol of women in technology and were celebrated widely posthumously by NASA and MIT, who recognized her as a trailblazer in an era before "software engineering" was even a common term.
