Now then, I don't want you to think I'm nit-picking, but can you provide a source doc. From a recent trip to Wiki, I get:
. . . After his short stay at Odessa University, Smakula returned to Germany as head of an optics laboratory in Heidelberg. From 1934 he worked at the Carl Zeiss AG company in Jena. While at Zeiss, in 1935, Smakula invented and patented optical anti-reflective coatings, a significant advance in optical technology. . .
Which is what I had already investigated and reported on. Arthur's question was about the invention of MULTI-coatings. Do you have anything on that?
So far, I've struck out.

INTERFERENCE coatings are multilayer. They have to be.
Single layers transform. To generalize to multilayer is to use INTERFERENCE.
An Physicist knows this. A technician probably does not.
Inventing and patenting multilayer coatings is some years away from
mass-manufacturing.
