Berliner's Earliest discs recovered?

[Angus McCarthy]

This is a fascinating article. It follows the same premise that was taken with the Phonautogram transfers which were made a few years back.



Apparently, Berliner submitted several of his earliest discs to be duplicated and physically printed in a popular magazine, so that people could see what the crux of his new invention actually looked like. The happy coincidence for us, 125 years later, is that they simply took one of his discs, and slapped it into the printing press like just another engraved image! One of the researchers who worked on the Phonautogram project stumbled across one of these prints, and has managed to recover audio of Berliner himself reciting a popular German poem, Der Handschuh.

The results:
