125 years ago in sound
The origin of recorded audio is frequently attributed to Edison, yet Emile Berliner invented the flat disc Gramophone that was the precursor to the modern record.
In the summer of 1887, Emile Berliner recorded in his own voice, “Twinkle, Twinkle Little Star”. In 1888 he filed and patented a talking machine which also recorded and played back sound. He called his talking machine the Gramophone. The main advantage of a flat medium disc was that thousands of records could be inexpensively pressed from one master. The Gramophone soon became the worldwide standard.
