Emile Berliner (1851-1929), German-US inventor. Berliner was born in Germany, and emigrated to the USA in 1870, becoming a US citizen in 1881. In 1887, he patented a gramophone that markedly improved the original 1877 design by Thomas Edison. It used a horizontal metal disc instead of a cylinder, producing less sound distortion. The metal disc reproduced sound by means of a series of undulations inscribed on its surface by a stylus. The disc was rotated by hand and sound was amplified through a conical horn. Plastic replicas of the discs could be made. Photographed on 12 April 1927, in Washington DC, USA.
