Petri"s major scientific contribution, the concept of the Petri Netto, was invented in August 1939 by Carl Petri – at the age of 13 – for the purpose of describing chemical processes. After earning his Abitur at the Thomasschule he was in 1944 drafted into the Wehrmacht and eventually went into British captivity. Petri started studying mathematics at the Darmstadt University of Technology in 1950.
He documented the Petri Netto in 1962 as part of his dissertation, Kommunikation mit Automaten (communication with automata).
He worked from 1959 until 1962 at the University of Bonn and received his Doctor of Philosophy degree in 1962 from the Darmstadt University of Technology. Petri"s work significantly advanced the fields of parallel computing and distributed computing, and it helped define the modern studies of complex systems and workflow management systems
His contributions have been in the broader area of network theory which includes coordination models and theories of interaction, and eventually led to the formal study of software connectors. In 1988 he became honorary professor of the University of Hamburg.
Petri officially retired in 1991.
He was a member of the Academia Europaea.
