Life and work

Born to a Jewish family in Hanover, Germany, 'Emil Berliner' emigrated to the United States of America in 1870, where he established himself in Washington, D.C. After some time working in a livery stable, he became interested in the new audio technology of the telephone and phonograph, and invented an improved telephone transmitter (one of the first type of microphones) which was acquired by the Bell Telephone Company. Berliner subsequently moved to Boston in 1877 and worked for Bell Telephone, until 1883 when he returned to Washington and established himself as a private researcher.
Emile Berliner became a United States citizen in 1881.
In 1886 Berliner began experimenting with methods of sound recording. He was granted his first patent for what he called the "gramophone" in 1887. The first gramophones recorded sound using horizontal modulation on a cylinder coated with a low resistance material such as lamp black, subsequently fixed with varnish and then copied by photoengraving on a metal playback cylinder. This was similar to the method employed by Edison's machines. In 1888 Berliner invented a simpler way to record sound by using discs. Within a few years he was successfully marketing his technology to toy companies. However, he hoped to develop his device as more than a mere toy, and in 1895 convinced a group of businessmen to put up $25,000 with which he created the Berliner Gramophone Company.

A problem with early gramophones was getting the turntable to rotate at a steady speed during playback of a disc. Engineer Eldridge R. Johnson helped solve this problem by designing a clock-work spring-wound motor. In 1901 Berliner and Johnson teamed up to found the Victor Talking Machine Company.
Berliner also invented a new type of loom for mass-production of cloth; an acoustic tile; and an early version of the helicopter. (There are mixed accounts of his early helicopter. Some say it successfully lifted two men off the ground in 1909, some say it was 1919. Not in dispute is the working helicopter that he and his son Henry Berliner demonstrated for the United States Army on July 16, 1922.)
Berliner was also active in advocating improvements in public health and sanitation.
Emile Berliner died of a heart attack at the age of 78. He is buried in Rock Creek Cemetery in Washington, D.C. alongside his wife and a son.
