One such approach that emerged was the monitor. First described by Per Brinch Hansen [BH73] and later reﬁned by Tony Hoare [H74], the idea behind a monitor is quite simple.

Brinch Hansen and Hoare developed the monitor concept in the early 1970s, based on earlier ideas of their own and of Edsger Dijkstra. Brinch Hansen published the first monitor notation, adopting the class concept of Simula 67, and invented a queueing mechanism. Hoare refined the rules of process resumption. Brinch Hansen created the first implementation of monitors, in Concurrent Pascal. Hoare demonstrated their equivalence to semaphores. outboard motor shaft length for pontoon boatNettetHoare l.
