While Unix users joke that the world did not exist before 1970,
agreed, and indeed you so commented.

In physics, hologram theory is due to Dennis Gabor, ca. 1947 and
laser holograms or holographs are very ubiquitious, even for
authentication (eg, VISA card). 

While Webster points out that the word "holograph"  dates back to ca.

That's why it's perhaps fortunate that this dialogue has shown that
two widely different words in their meaning, such as holograph
(whole-field picture) and holograph (handwritten signature) have
equal forms ... and similar use for authentication...

Point taken that legal use was first and that physicists just
shamelessly copied the word.

I plead guilty!

And, maybe your point of using holograph for one and hologram for
another is indeed a good solution, while we may have of course to
still live with holograph holograms and hologram holographs ...while
not with holograph holographs...
