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 onboard 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.

The error detected the computer was overloaded, and for a moment it looked like the complex landing might not be achieved.

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.

The team’s famous software engineering was immortalised in a 1969 photograph of Hamilton standing beside the stack of printed code that towered beside her.
