Koszul

Aron Simis sends in this photo of Jean-Louis Koszul, taken in Grenoble France.
Aron writes, “I wonder if this of interest to the community to post the picture. I consider it quite rare, since I spent most of my mathematical life talking about “Koszul” and finally met my mathematics in person!”
Also in the photo (l to r): Marcel Morales, Mikhail Zaidenberg, ??, Koszul, Simis, Lê Tuân Hoa, Santiago Zarzuela.
