When Thomas Edison invented the phonograph everyone thought he could do almost anything. An April 1st headline on the New York Graphic stated he had invented a "Food Machine" This letter was Edison's response to that piece and his comments to the editor of the paper Mr. Croffutt...
The headline was one to get attention all over the USA, causing people to start contacting Edison to order food machines. This was a great moment for Edison as he gave to the editor a phonograph and sent to him this letter with the bit of fun on the back...The phonograph so amazed him Mr. Croffutt called Edison the Wizard of Menlo Park....It was name that stuck....
Basically over a April Fool's joke and the phonograph... It would always be the name Edison would be known as...The Wizard of Menlo Park....Now you know how he got that name..We are still waiting for the food machine though..
