Emile Berliner
Emile Berliner originally Emil Berliner, was a German-American inventor. He is best known for inventing the lateral-cut flat disc record used with a gramophone. He founded the United States Gramophone Company in 1894; The Gramophone Company in London, England, in 1898; Deutsche Grammophon in Hanover, Germany, in 1898; and Berliner Gram-o-phone Company of Canada in Montreal in 1899.

Phonograph record
A phonograph record or a vinyl record is an analog sound storage medium in the form of a flat disc with an inscribed, modulated spiral groove. The groove usually starts near the outside edge and ends near the center of the disc. The stored sound information is made audible by playing the record on a phonograph.
