This is treated in any book on analog computer design.
See the books by G.Korn for more than you want to know.

Everything in a modular synth existed to some degree before Moog.
His contribution was standardising everything, and making it
voltage controlled in a matching way.

I have heard that it was john Simonton at PAiA who first called them
'analog synths' after the analog computers. The transistorised 
analog computers of the day look like a modular synthesist's wet dream.
