Henry Ford was a BIG fan of Thomas Edison. So much so that Ford moved Edison's Menlo Park, NJ laboratory to his Greenfield Village museum in Dearborn, Michigan.
In 1929, the 50th anniversary of Edison's invention/perfection of the incandescent light bulb, Henry Ford, President Hoover, and Thomas Edison gathered in the laboratory and Edison recreated the invention of the light bulb. The newsreel cameras were rolling. Grabbed this screen shot. Edison is sitting in the chair:
Henry Ford was so enamored with Thomas Edison that, after the event, he ordered the chair to be nailed to the floor and
never moved. It remains there to this day. Notice how the floor
around the chair has been replaced, but the chair remains exactly where it was in 1929. I think that's pretty darn cool.
Ford also had Edison come to Michigan the year before for the groundbreaking of the museum. Ford had Edison stick a shovel into a large block of wet cement and sign his name. It, too, remains in place.
Now, every time I see that block of cement I can't help but think how cool that would look in my man cave ... and I am reminded of the time Lucy stole John Wayne's concrete footprints from Grauman's Chinese Theater ...
