I was recently reading the new bio of Edwin Land. Besides learning that the
family name was Salomonovitch and it was thought that his father mistook
the immigration officials saying "You are now landed" as the source of the
family name there was a couple of other tidbits that look like areas for
exploration. Perhaps someone has already exploited this function. 3M Color
key perhaps???

1. Polyvinyl alcohol absorbs dye. The early base for Land's polarizing film.
2. Polyvinyl alcohol hardens in light like gum if dichromated.

Coat PVA on plastic sheets. Dichromate. Expose and then dye the sheet.

Just thought I'd pass it on.

Hmmm. It could have been the Polaroid Salomonovitch Camera.
