Margaret Hamilton, the computer scientist who built the software for the Moon landings, has died at 90. She pioneered the field of software engineering.
The Massachusetts Institute of Technology confirmed her passing. She worked at MIT from 1959 until the mid-1970s. She managed the division that built all onboard flight software. Her team coined the term software engineering during those years.
Why this matters
Hamilton remains a hero for women in technology. She entered a male-dominated field long before it was common. Her code successfully handled a critical computer error during the Apollo 11 mission.
Also, her priority-driven software design kept the mission on track. It shut down less important background tasks during the landing. This decision saved the mission from a potential failure.
Meanwhile, modern technology relies on principles she helped establish. Every smart device today uses concepts from her early research. Her legacy lives on in modern space and computing systems.
A Legacy in Code
Hamilton arrived at MIT in 1959. She originally took the job to support her husband through law school. She quickly became the first programmer to join the space project.
Next, she earned fame for her dedication to the craft. A famous 1969 photo shows her next to a stack of printed code. That stack was as tall as she was.
After that, the government honored her many contributions. President Barack Obama awarded her the Presidential Medal of Freedom in 2016. He called her a symbol for many unsung women in science.
Life and Career
Hamilton was born in Indiana in 1936. She studied mathematics at the University of Michigan starting in 1955. She finished her degree at Earlham College in 1958.
Then, she moved to Boston to start her life and career. She founded her own company later in the 1970s. Hamilton Technologies continues to operate in Massachusetts today.
Still, friends and colleagues remember her pioneering spirit. Earlham College expressed sadness over her death. They also noted their gratitude for her long life of work.
