In memoriam Jean-Raymond Abrial (on www.linkedin)

 I am saddened to report (from today's print version of Le Monde) the passing away of the great French computer scientist Jean-Raymond Abrial. He is a pioneer in formal methods and their applications, particularly through three major innovations:

- The "Data Semantics" model.

- The two successive versions of the Z specification language.

- The remarkable B method and tools. One of the most spectacular achievements of practical formal methods was the groundbreaking verification of the security system of the Paris Metro's "Line 14".

A major loss for computer science.

Very sad news.
JR ABRIAL was also a great creator of real time programing language. He wrote the spécification of LTRv2 in the 60s when participating in the création of the Centre de Programmation de la Marine as a young navy engineer. LTRv2 was heavily used in the 70s and the 80s to develop many real time complex information systems, military and civilian. Later at the end of the 70s he was a key participant to the « green » team of Jean Ichbiah which created ADA. Z was first developed as a way to rigorously specify ADA programs.
I worked in CPM as a Young navy engineer in the 80s but unfortunately I never met JR ABRIAL who was already a legend…. RIP JRA…

 

<< A major loss for computer science >> : and also for software engineering. The B method is an almost unique case of a bridge between these two areas. Because Abrial was an almost unique person with one foot in each world.

Sad news. Jean-Raymond Abrial was a giant in computer science and software engineering, upon whose shoulders much of the field of formal methods still stands.

Thanks Bertrand for informing me. We had a full day in nantes last week for celebrating the achievement of Jean-Raymond but we did not know that he passef away the day before. A great scientist with strong ideas which will be still to pics of future researched and phd.
I Remember my visites in Marseille and our walks. In the lanes and streets in Marseille
 
 
sad news, with Prof. Börger they make me love formal methods
He was a true inspiration, especially to us Formal Methods researchers. He did not give up on the key ideas: Formal semantics for precise meaning, formal modelling languages for abstraction, refinement as a method, proof for highest insurance, tools to support the user, and most importantly real-world projects that speak for themselves. Jean-Raymond, we keep your ideas alive! Requiescat in pace.
 
 
Thank you Bertrand for sharing this information.
I have personnally learnt a lot from his inspiring work and his recommendations.
I am sad and extremely gratful to JRA. I will miss him a lot.
Next ABZ in Dusseldorf next week will pay a tribute to his memory. See you tehre for those who are particpating
Many thanks
All the best

A huge loss indeed...
 
A great man and a great loss.
 
Sad news indeed. I had the privilege of attending a week-long seminar on the B method circa 2004. He was a wonderful teacher, with a great sense of humor and style. He had used illustrative examples from the Paris Metro system in that seminar.
 
So sad to hear the news. Jean-Raymond was a true inspiration, someone with a vision not just for theory but even more so for practical application of formal methods. Perhaps thanks to his work on B I decided to do a PhD in the first place. 😢

Very sad news indeed!
I followed Jean-Raymond's seminal work from the first steps towards the introduction of Z specification language in the early 70's!
His commitment to Bourbaki's work has led to major contributions to computer science.
After Z, his contribution to the "green proposal" leading to the definition of ADA language, was an example.
At the end of 70's, being myself on leave from INRIA at the Oxford Programming Research Group, Tony Hoare asked me to suggest an "original researcher" from France he could invite for a stay at the PRG. Without hesitation, I suggested Abrial.
In contact with Hoare's CSP, his work on the B method (from Bourbaki) was done with the success we know: B book.
Later in the 1990s, he suggested to come to Marseille to collaborate with my research group on formal methods for communicating parallel systems.
Then, Atelier B from CLEARSY, after a first success for the design of the embedded software for the Meteor project with RATP-first automated metroline in Paris, was our choice to be proposed within a successful EU-FP6 project we have set up by 2000: "MATISSE - Methodologies and Technologies for Industrial Strength Systems Engineering" https://cordis.europa.eu/project/id/IST-1999-11435

RIP J-R!
 
Jean-Raymond was an amazing teacher, with a great sense of humour and an infectious enthusiasm for formal methods that made his students realise proofs aren't that scary after all. A great explorer and a fantastic person to be around also outside of formal settings. Rest in peace, J-R!
 
Une intelligence rare, la volonté d’une recherche appliquée utilisable pour des grands projets industriels… des systèmes sont prouvés grâce à lui
  
 
A shining beacon for my own research. Thanks for sharing, Bertrand
Thanks for sharing, Bertrand. Not only a loss for computer science, a loss as a friend. See also https://en.wikipedia.org/wiki/Jean-Raymond_Abrial
Sad news he helped me a lot to learn B and Event-B
Sad news. Jean-Raymond Abrial was a giant in computer science and software engineering, upon whose shoulders much of the field of formal methods still stands.
I am very sorry to hear this sad news. His work on data models was influential as well. E.g., it influenced entity-relationship models.
Thank you, Bertrand, for sharing the news. This is very sad. I am lucky to have met Jean-Raymond Abrial several times and worked with him as part of my Ph.D. thesis. He was very rigorous in his research and had such good pieces of advice. He was not only a great scientist but also a very nice person to work with. I always kept in touch since then. Thanks, Jean-Raymond, for all the nice exchanges we had.
A huge loss indeed...

May he rest in peace!
A gentleman, free-spirited, a great scientist, enthusiastic and inspiring. Hats off to him!
I first met Jean-Raymond in Nantes in 1996.
We will miss him forever.
 
 
 
I first saw Jean-Raymond Abrial at AFADL when I was a PhD student. I was in awe of the master, the inventor of the very method I use in my work. The B method has become the backbone of the tools I develop. May he rest in peace.
  
J'ai cotoyé (un peu) JR Abrial au début des années 2000, ses travaux ensuite. C'est un exemple de rigueur et d'honnêteté intellectuelles sans compromis
 
I had the opportunity to work with Abrial in the late 90’s early 2000’s in particular on the automation of the Paris metro. On this occasion I was able to appreciate the intelligence and elegance of his reasoning.

His death is is sad news
 
Sad to hear that. We use "Rodin" in our teaching, so Jean-Raymond's legacy lives on.
 
Sad to hear. Indeed, a great loss.
 
I remember the B Book, when i was student during my thesis. And some exchanges i had by email..
 
Deeply saddened by the passing of Jean-Raymond Abrial — a true pioneer of formal methods. His contributions, from Z to the B Method, shaped generations of rigorous system design. His legacy will endure.
  
Very sad to hear this news. Much of the math for my PhD (almost) 20 years ago was based on his classic The B Book, which I sill treasure on my bookshelf.
 
He was teaching at Marktoberdorf in 1996 when I was a PhD student, and was trialling some of the material that eventually became The B Book. He was insightful, helpful and took my naive questions in absolutely the best way. A gentleman and a scholar.
 
I remember his kindness. During an internship as a student I wrote a plugin for Rodin and he sent an email to thank me.
  
Maria Husmann Jean Raymond Abrial was not only kind but as well humble. As an example that formal methods do not automatically lead to meaningful systems, he reminded us that to specify one should be allowed to enter a room should normally imply one should be allowed to leave it as well. He mentionned a well known public building in Paris which forgot to specify this property in the design of the access control system and staff had to patrol each room daily until an update ensuring this safety could be rolled out.

I was very fortunate to attend his Marktoberdorf course on Event-B when I was a PhD student. He was a wonderful person and a brilliant scientist whose deep contributions continue to reverberate.
 
Merci Bertrand Meyer . J'ai eu le bonheur de l'avoir comme professeur à l" Grenoble INP - Ensimag en 1969-1970. Cours où il nous decortiquait une de ses créations les moins connues mais peut-être la plus "basique" avant sa période "abstraite". La base de données Socrate, un bijou mélangeant élégance efficacité et facilité d'usage. Un grand monsieur à l'allure stricte et degingande qui nous impressionnait.
 
I am very said about that. a fantastic researcher with a huge contribution to critical systems.
 
I met Abrial several times going back to Zed he was someone that I thought set great example on how to design useful formal methods
  
Yes indeed, very sad news!
My personal testimony in a separate post, titled EN L’HONNEUR ET EN SOUVENIR DE JEAN-RAYMOND ABRIAL.
 
Sad news indeed and a true loss for our discipline. I met Jean-Raymond at Pune in India at an event organized by Tata Consultancy. He was a true gentleman.

In the Advanced Software Engineering course I gave at Monash University, we chose his Event-B approach as an introduction to formal methods.
 
Very sad. He was a true inspiration
 
This is very sad news. Jean-Raymond had a huge influence on my research and was a wonderful person to work with. Inspiring and encouraging. He will be missed.
