I am very sorry to inform you that the farther [sic] of our research area,
Carl Adam Petri, has passed away a few days ago.
Carl Adam Petri has had a tremendous influence on the theory of concurrency
and many other areas of science. We are all very grateful to him for laying
the foundation for our flourishing research area.
Petri, a German mathematician and computer scientist, was a pioneer of research in concurrent systems. He invented Petri nets, a formalism to describe and analyze dynamic, concurrent behavior. Any researcher working in process modeling or process mining, among many other fields, knows what we owe to his contributions.
