R. Guillominot Boespflug & Cie, in France, which was the actual
manufacturer of Zone VI Brilliant paper, has been around since the late
1800's. It looks like they were making papers back then.

After they closed, some former employees of the company bought it and
re-opened under the name Bergger paper.

The very first enlarging papers must have appeared on the market
in the mid-1920 mirroring the popularity of small formats like Rolleiflex
and Leica which was producing some of the first enlargers.
What papers were first available for enlarging and their speed?
Who was first to come out with enlarging papers?
Thanks! Rich
