Thomas Edison has an impressive 2,332 worldwide patents. Some of his well-known inventions include the phonograph, motion pictures, and the magnetic iron ore separator. After the success of his first major invention, the quadruplex telegraph, Edison wanted to build his own laboratory so that he could continue to innovate. In 1875, he purchased around 34 acres in Raritan Township, NJ and built the "Invention Factory". By Spring 1876, the Invention Factory consisted of a main laboratory, ancillary buildings, a carpenters’ shop, carbon shed, and blacksmith shop. His first breakthrough at the Invention Factory, the phonograph, produced the first voice recording (“Mary Had a Little Lamb”) and earned Edison the title, “The Wizard of Menlo Park”.
