Gramophone patented

In 1887, Emile Berliner (1851 - 1929) filed for a patent for his invention of the lateral-cut, flat-disk gramophone on this day. We know it better as the record player. Emile got the patent, but Thomas Edison got the fame (for making it work and making music with his American invention). Berliner's legacy also lives on in his trademark (later adopted by RCA): a picture of a dog listening to "his master's voice" issuing from a gramophone.
