Otto von Bismarck's voice now known not just to the dead

Nice!

It was lost for 123 years: the only audio recording of Chancellor Otto von Bismarck (1815 - 1898). The recording was found in a dark corner of the New York Edison archives, and can be listened to, albeit only very poorly.

The audio can be heard here, and it really is bad. Apparently it's an excerpt of Gaudeamus igitur, Allons, enfants de la Patrie (Marseillaise), and an exhortation to his son to do everything in moderation.

I tried a noise removal in Audacity and it ended up sounding pretty weird - perhaps somebody else will do a better job, in which case I'll update the post with a better link.
