Thomas Edison's Greatest Invention
This clip was taken from an hour-long Q&A session following a recent program. The audience was one of the most astute and intelligent I have ever had. In this video you may be surprised to learn what Thomas Edison credited as his greatest invention.The question posed was not his 'favorite', but rather what he considered his 'greatest'. His favorite was the Phonograph. See if you can think of what he might have said before you play the video. Clue: It wasn't the light!
