some interesting  stuff  here    at the time  the UK had  not   
declassified  so  that  part of the story is  thin when I  did this

My reading of the history of the  proximity fuse (a/k/a VT fuse) says
that VT was weaponized under the  direction of Navy Capt. Deke Parsons at 
the
Applied Physics Lab in Silver  Spring, MD, just down the road from me.  As a
reward for his efforts,  Deke was transferred to the Manhattan project to
turn the Trinity device  into the Fat Man and the uranium-based Little Boy
into the first atomic  balm used in combat.

Also, VTs initially were not  permitted to be used in ETO for fear that
the duds that fell on land could  be reverse engineered when recovered.
Hence, their first use was in PTO  where duds would fall into the sea.

Subject:  [Milsurplus] Proximity fuses

There is an article in the most recent  issue of Electric Radio Magazine
which talks in detail about Mr. Butement,  born in New Zealand, moved first
to Australia, then to England whose ideas  and experiments resulted in the
proximity fuse.

I see that the paper  from India linked for us by Ed also mentions Butement.

Apparently,  though, the U.S. was the only country who was able to
successfully BUILD  them, although many other countries were attempting to
develop them,  including Germany in the 1930s.

Also, Sylvania is prominently mentioned  as the only company who could build
sub-mini tubes in the quantity and  quality needed.
