The reason I asked is that we already discussed about this issue
before, either here or at another list, and you are repeating it.
Last time I pointed out that Trivelli and others were studying grain
morphology and photographic properties of emulsions and he found no
instance of grain clumping despite very early reports on such a
phenomenon from 1910's or 1920's. I was wondering if you had any
further evidence that requires to change the view. I think I gave you
the reference last time, but it's published in J. Franklin Institute.

That just means that at least one bozo at Kodak advertising department
didn't know about it and it doesn't mean no one at Kodak knew about
it. Papers written by Kodak researchers such as Levenson about history
of developers correctly credit Capstaff's work.
