Cutler have most credit for RSX-11M, but RSX-11M was just a 
reimplementation of RSX-11D. Same API, but redesigned internals.
And RSX-11D comes from -11C, and eventually you can trace it all back to 
RSX-15, which was written for the PDP-15...
So many of the ideas and concepts had already been done before Cutler.

One thing Cutler did, which you do not find in the predecessors are ACPs.
