Who invented the "cache"?

Question for the old-timers:

Who came up with the concept of "cache" or "cached memory"? When? And
what is the first written reference to it?

I suspect it appeared in the 70's, but it could be older than this.

(Am I in the right newsgroup?)

A: Because it messes up the order in which people normally read text.
Q: Why is top-posting such a bad thing?
A: Top-posting.
Q: What is the most annoying thing on usenet and in e-mail?

It was almost certainly IBM- and disclosed in the IBM Journal.
 
One of the first computers, the Manchester University machine, circa 1951,
used a CRT screen (very unreliable electrostatic storage), to hold blocks
recently read from the drum.
This is pretty much a cache.

Right! The invention of cache can then be attributed to the first
Ugha-Ugha cave man who discovered it was easier to store water in his
cave than make a trip to the river each time.

As old as that! But who came with the name? I guess I may have to check
with IBM, as Fred Bloggs suggests.

In that case, it was probably a woman.

The word itself goes way back to cacher, french, to press, hide. So
it's no different than calling a CCD a bucket-brigade delay. Just a
new use for an old word.

But it could have been named anything else. Who decided to call it
"cache" instead of FTM (Fast Temporary Memory), for example?

So who was responsible for flushing the cache?
