In 1890, Thomas Edison designed one of the first talking dolls. By using a small phonograph, another of Edison's inventions, the doll could play recordings of nursery rhymes and lullabies. The dolls were made of wax and were originally marketed as a technological marvel, with parents eager to purchase them for their children.
Unfortunately for Edison, the dolls weren't a commercial success, as the sound quality was poor and the mechanical inner workings made the dolls expensive to produce. Nevertheless, the talking doll remains an interesting example of Edison's inventive spirit and his willingness to explore new technologies. The dolls are now highly sought-after collector's items, with some selling for tens of thousands of dollars at auction.
