Jean Ichbiah, developer of the Ada programming language, died last week.
Ada was developed specifically for the US military and, over 10 years of use, changed the way US military and Nato built embedded computer systems.
The programming language was named after Lady Ada Lovelace, daughter of the poet Lord Byron.
Ichbiah went on to also develop a fast text entry system for handheld computers.
During his lifetime he was awarded with the French Legion d'Honneur; a Certificate of Distinguished Service by the US Department of Defense; and was a Member of the French Academy of Sciences
