His name may not be familiar to you, but Alain Colmerauer played an important role in the invention of artificial intelligence. And believe it or not, his story is also linked to our beautiful city of Marseille.

Who is Alain Colmerauer?
Alain Colmerauer (1941–2017) was a French computer scientist recognized worldwide as one of the pioneers of artificial intelligence. After spending part of his career in Canada, he joined the Luminy Faculty of Science in 1970, where he spent most of his academic career, even becoming a full professor. It was in Marseille that he designed “Prolog,” a computer language that profoundly influenced the development of AI by enabling machines to reason based on logical rules.
His work placed Marseille at the heart of an international scientific revolution, particularly through research in logical programming and collaborations with the major Japanese “fifth-generation computers” project. Thanks to Colmerauer, Marseille is not only a city of history and culture, but also a key location in the birth of modern artificial intelligence. So even though he was not born in Marseille (he was born in Carcassonne), the city inspired him to undertake a truly remarkable project!
What is Prolog?
Prolog is a special computer language that does not tell the computer what to do step by step, but simply provides it with facts and logical rules, then asks it a question. The computer then uses this information to reason and find the answer itself, much like a detective connecting clues. This approach, called “logic programming,” solves problems by describing the relationships between things rather than detailing a sequence of actions, and has been used particularly in artificial intelligence and for systems capable of drawing conclusions automatically.
And AI today?
Today, technological advances have done their job and AI has a central place in our society. The most significant technological revolution of the 21st century, although at the heart of current social debates, continues to evolve day by day. We’ll let you be the judge of whether this is good or bad news, and the best way to illustrate this duality is undoubtedly in the interactive play The Jury Experience. In this trial, an autonomous car is at the center of an accident, and it’s up to you to decide who is responsible.
