Cellophane
On May 26, 1914, Swiss chemist Jacques E. Brandenberger applied for a patent (awarded on May 21, 1918 as patent number 1,266,766) for a method of producing composite cellulose film, a.k.a. cellophane. Actually, I have no idea if this is true cellophane or some other film, but I think of it as cellophane, in any case. I spent the evening assembling and packaging photographs for the upcominb WCA Christmas Bazaar on Saturday and this is my trash bin, full of wrapping material.
