[PlanetKR] In Memoriam Joe Halpern

[Gabriele Kern-Isberner]

Dear KR community,

I've just received sad news -- Joe Halpern, a pioneer of knowledge 
representation and reasoning methodologies, passed away at the age of 72 
on Feb 13.

At KR 2024 in Hanoi, Sheila McIlraith and Murray Shanahan had a 
conversation with Joe Halpern about "Great Ideas from KR: drawing on the 
past to shape the future", please see 
https://kr.org/KR2024/invited_speakers.php .

Cornell University published a website in memoriam of Joe Halpern:

Sad regards,

     Gabriele Kern-Isberner
     (current President of KR Inc)
