I am amazed to find out HOW MANY companies have put their
names on crystals over the years. Do you know of more?
These names will likely be lost to obscurity in a few years
if we do not somehow memorialize them here or in our publications.
I count over 110 companies so far, although I suspect some were
duplicate outfits operating under different names. many of these
firms had to have had their own machinery for making the crystals.
Most of these firms existed in the 1940-160 era, which was the heyday
of radio crystal manufacturing. Quite a short period of time, when
you think about it! You have to wonder what happened to all of these companies!
