Margaret Hamilton, Apollo software pioneer who helped define the field, dies at 90
Margaret Hamilton, who led the MIT team that built onboard flight software for NASA's Apollo missions and helped establish software engineering as a discipline, has died at age 90.

Margaret Hamilton, the American computer scientist who led onboard software development for NASA's Apollo missions and helped establish software engineering as a discipline, died on September 30 at the age of 90. Her former employer announced the death on Wednesday, according to reporting from MIT News and international news outlets.[2][3][7][1]
Hamilton led the software team at MIT's Instrumentation Laboratory, directing what The New York Times reported as a 100-person group that wrote the onboard code for the lunar program. Her team was responsible for developing the flight computer systems that guided the spacecraft to the moon.[4][6][7]
Her pioneering software played a critical role in the first moon landing in 1969. During the Apollo 11 descent, priority scheduling and error-recovery features built by Hamilton's team silenced computer overload alarms, keeping astronauts Neil Armstrong and Buzz Aldrin safely on course for landing.[5][6]

Apollo software pioneer Margaret Hamilton dies at 90. Margaret Hamilton, who led the software team at MIT's Instrumentation Laboratory, developed the onboard flight computers that guided NASA's Apollo missions, including the safe Apollo 11 landing in 1969. During that historic descent, her team's priority scheduling and error-recovery features silenced overload alarms and kept Neil Armstrong and Buzz Aldrin on course. In the picture, Margaret Hamilton stands next to the navigation software that she and her MIT team produced for the Apollo Project (1969).
