1860. They say it's like listening to a ghost http://www.firstsounds.org/sounds/index.php coolest part is that it was 17 years before the Edison invented the phonograph http://www.msnbc.msn.com/id/23835160/
Pretty amazing. Thomas Edison must have had some family members writing the history books here in America. Nikola Tesla is another who's name often goes unmentioned, because of Edison hype.
