Jean David Ichbiah (25 March 1940 – 26 January 2007)[1] was a French computer scientist. From 1977 to 1983, he was the chief designer of Ada, a general-purpose, strongly typed programming language with certified validated compilers.[1]

Early life

Ichbiah was a descendant of Greek and Turkish Jews[1][2] from Thessaloniki who emigrated to France.[3]

Career

In 1980, he founded the Company Alsys. From 1972 to 1974, he worked on designing an experimental system implementation language called LIS, based on Pascal and Simula.[4] He had been chairman of the Simula User's Group and was one of the founding members of IFIP WG 2.4 on Systems Implementation Languages.[5]

He then joined CII Honeywell Bull (CII-HB) in Louveciennes, France, becoming a member of the Programming Research division.[1] Among other projects, he worked on the rewrite of the Siris 7 operating system into Siris 8 computer restructuring Iris 80 .

Ichbiah's team submitted a language design labelled "Green" to a competition to choose the United States Department of Defense's embedded programming language. When Green was selected in 1978, he continued as chief designer of the language, now named "Ada". In 1980, Ichbiah left CII-HB and founded the Alsys corporation[1] in La Celle-Saint-Cloud, which continued language definition to standardize Ada 83,[1] and later went into the Ada compiler business, also supplying special validated compiler systems to NASA, the US Army, and others. He later moved to the Waltham, Massachusetts subsidiary of Alsys.

In the 1990s, Ichbiah designed the keyboard layout FITALY, which is specifically optimized for stylus or touch-based input. Subsequently, he started the Textware Solutions company, which sells text entry software for PDAs and tablet PCs, as well as text-entry software for medical transcription on PCs.

Awards and honors

In 1979, Jean Ichbiah was designated a chevalier (knight) of the French Legion of Honour[1] and a correspondent of the French Academy of Sciences. He received a Certificate of Distinguished Service from the United States Department of Defense for his work on Ada.

Death

Jean Ichbiah died from complications of a brain tumor on January 26, 2007.[6]
