## Summary
Jacques Pitrat was a French artificial intelligence scientist who spent most of his career as a senior researcher at CNRS (Centre national de la recherche scientifique). He was a pioneer of AI research in France, known for his work on metaknowledge and his role in establishing AI as a legitimate field of study in French academia.

## Biography
- Born: 1934-02-27 in Bourges, France
- Died: 2019-10-14 in Chevilly-Larue, France
- Nationality: French
- Education: École polytechnique (graduated 1954), University of Paris (PhD 1966)
- Known for: Pioneering artificial intelligence research in France
- Employer(s): National Center for Scientific Research (CNRS) from 1967
- Field(s): Artificial intelligence, computer science

## Contributions
Jacques Pitrat was instrumental in establishing artificial intelligence as a legitimate research field in France. Working at CNRS from 1967, he built a research program focused on metaknowledge - knowledge about knowledge - which became his signature contribution to the field. His work on systems that could reason about their own reasoning processes was ahead of its time.

Pitrat supervised numerous doctoral students who went on to become prominent computer scientists themselves, including Jean-Louis Laurière, Anne Adam, Tristan Cazenave, Jean-Pierre Laurent, and Joël Courtois. Through his teaching and mentorship, he created a generation of AI researchers who carried forward his vision of intelligent systems.

His research emphasized the importance of self-reflection in artificial intelligence systems. He argued that truly intelligent systems needed not just knowledge, but knowledge about how to use that knowledge - what he termed metaknowledge. This approach influenced how French researchers thought about AI architecture and system design.

## FAQs
### Q: What was Jacques Pitrat's role in French AI research?
A: Pitrat was a pioneer who established AI research at CNRS and supervised multiple generations of French AI researchers. He led research into metaknowledge systems and helped legitimize AI as an academic discipline in France.

### Q: Where did Jacques Pitrat work?
A: He spent his entire research career at the National Center for Scientific Research (CNRS), France's largest government research organization, starting in 1967.

### Q: What is metaknowledge in AI?
A: Metaknowledge is knowledge about knowledge itself - understanding what you know, how you know it, and how to use that knowledge effectively. Pitrat argued this self-reflective capability was crucial for truly intelligent systems.

### Q: When did Jacques Pitrat receive his PhD?
A: He earned his Doctor of Philosophy degree from the University of Paris in 1966, the year before joining CNRS.

## Why They Matter
Jacques Pitrat's significance lies in his foundational role in establishing French artificial intelligence research. At a time when AI was not widely accepted as a legitimate scientific discipline, he created a research program at CNRS that produced influential work on metaknowledge systems. His emphasis on self-reflective AI systems anticipated later developments in meta-learning and AI safety.

His influence extended through his doctoral students, who became leaders in French computer science. The research tradition he established at CNRS created a pipeline of AI researchers who carried forward his vision of intelligent systems that understand their own reasoning processes. Without his early advocacy and research, France's AI research community would have developed differently, likely following trends from the United States and United Kingdom rather than developing its own distinctive approaches to AI architecture and knowledge representation.

## Notable For
- AAAI Fellow (1994) - recognized for pioneering AI in France and contributions to metaknowledge research
- Director of Research at CNRS - senior position in France's premier research organization
- Doctoral advisor to multiple prominent French computer scientists
- Pioneer of metaknowledge research in artificial intelligence
- Established one of the first sustained AI research programs in France

## Body
### Early Life and Education
Jacques Marie Joseph Pitrat was born on February 27, 1934, in Bourges, France. He entered the prestigious École polytechnique in 1950 and graduated in 1954. After his undergraduate studies, he pursued doctoral research at the University of Paris, earning his PhD in 1966 under the supervision of René de Possel, Jean Ville, and Jacques Arsac.

### Career at CNRS
In 1967, Pitrat joined the National Center for Scientific Research (CNRS) as a researcher, beginning a career that would span over five decades. He rose to the position of Director of Research, CNRS's senior research rank. Throughout his tenure, he focused on artificial intelligence, particularly on systems that could reason about their own knowledge and reasoning processes.

### Research on Metaknowledge
Pitrat's central contribution was his work on metaknowledge - the idea that intelligent systems need not just knowledge, but knowledge about how to use that knowledge. This self-reflective approach to AI was innovative for its time and influenced how French researchers approached AI system design. His work anticipated later developments in meta-learning and AI systems that can monitor and improve their own performance.

### Legacy
Jacques Pitrat died on October 14, 2019, in Chevilly-Larue, France. His legacy lives on through the researchers he trained and the research tradition he established. The French AI research community continues to reflect his emphasis on theoretical rigor and systematic approaches to building intelligent systems.
