Emile Berliner, a German-American inventor, developed microphone patents in the late 1870s. While a legacy record suggests a March 1877 date in Washington, D.C., supplied passages indicate his key microphone patents were filed in 1879 and issued in 1880. Berliner worked for Bell Telephone, where his designs found commercial use, though a 1901 court ruling later voided his patent in favor of Edison.
Episodes
- Employment by Bell Telephone
Berliner's microphone designs found commercial success through use by Alexander Graham Bell, leading to Berliner's employment by Bell Telephone.
- Berliner Microphone Patent Filings
Berliner filed multiple microphone patents in 1879, including carbon diaphragm and loose carbon rod designs, which were issued in 1880.
- Patent Voided by Court
In 1901, the United States Court of Appeals declared Berliner's patent void, awarding full rights to Edison.
Background and detail
Background. Emile Berliner, born in Hanover in 1851, migrated to the United States in 1870 to avoid military service. He initially worked in a shop in Washington, D.C., before moving to Boston in 1877. His work in telecommunication involved developing devices that converted sound into electrical signals, a process central to the function of microphones in telephones and broadcasting.
Patent Timeline. Berliner's microphone patents were filed in 1879 and issued in 1880, contradicting the legacy hint of a March 1877 date. Specific patents included a carbon diaphragm microphone (filed August 1879) and a loose carbon rod microphone (filed September 1879). A combined telegraph and telephone patent was filed in June 1877 but not issued until 1891, highlighting the complex legal timeline of his inventions.
Legal and Commercial Context. Berliner's microphone designs were commercially successful through their use by Alexander Graham Bell, leading to Berliner's employment by Bell Telephone. However, legal disputes arose regarding priority. In 1901, the United States Court of Appeals declared Berliner's patent void, awarding full rights to Edison, who had preceded Berliner in the transmission of speech using carbon in a transmitter.
