​Dykstra invented the ukernel -- its the THE kernel:
https://en.wikipedia.org/wiki/THE_multiprogramming_system

The paper itself is
http://uosis.mif.vu.lt/~liutauras/books/Dijkstra%20-%20The%20structure%20of%20the%20THE%20multiprogramming%20system.pdf

And all kernel hacker should read it some time.  It where the idea of
semaphores are defined and the idea of "up" and "down" - (aka P/V).

Well, in all fairness, semaphores were used on railways already in the 19th century...
