Besides, the museum displayed all of his inventions--it is extensive and very interesting. The day was getting late so I didn't get to see all of the exhibits--it would have taken hours.
But he invented the Edisonphone--the first dictaphone. Ugh! That brought back ugly memories.
And the inventions went on and on. But my favorite of all is the catch-phrase that came from his most popular invention--the phonograph. The earliest ones (shown above) did not have a volume knob so the loudness was dictated by the size of the horn. When some neighbor complained about the noise from that 'newfangled gadget' it became a practice to remove an article of clothing and push it down into the horn to muffle the noise. The best article for this purpose was a pair of socks. Hence, when you want someone to 'shut up' you tell him, "Put a sock in it!" And for that you can thank Thomas Alva Edison!
