It's a bit tricky tracking this stuff down.  But, so far, I have 
found that the UHF connector was invented by E. Clark Quackenbush at 
the American Phenolic Company (Amphenol) in the 1930s. (at least this 
is what the Amphenol RF catalog says)

One also might find this

an interesting summary.

That ap note cites an IEEE paper by Bryant in the IEEE Trans on MTT, Sept 1984

It also cites a paper about blue dot precision N connectors published 
at JPL (so now I know what those connectors are down in the lab.)


Another source (one Andrew Emmerson) credits Quackenbush, and 
comments that in the late 30s, UHF meant frequencies over 100 MHz.
