Victor Orthophonic Victrola
The Victor Orthophonic Victrola, first demonstrated publicly in 1925, was the first consumer phonograph designed specifically to play electrically recorded phonograph records. The combination was recognized instantly as a major step forward in sound reproduction. Electrical recording was developed by Western Electric, although a primitive electrical process was developed by Orlando R. Marsh, owner and founder of Autograph Records. Western Electric demonstrated their process to the two leading recording companies, Victor and Columbia, who were initially unwilling to adopt it because they realized it would make their entire existing record catalogs obsolete. However, parched revenues in the record industry caused by the mushrooming new medium of radio soon forced both Victor and Columbia to begin experimental electrical recording., p. 142-3 The design of the Orthophonic was informed by progress in telephony and transmission-line theory. It was developed by two Western Electric rese ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gramophone Record
A phonograph record (also known as a gramophone record, especially in British English), or simply a 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 periphery and ends near the center of the disc. At first, the discs were commonly made from shellac, with earlier records having a fine abrasive filler mixed in. Starting in the 1940s polyvinyl chloride became common, hence the name vinyl. The phonograph record was the primary medium used for music reproduction throughout the 20th century. It had co-existed with the phonograph cylinder from the late 1880s and had effectively superseded it by around 1912. Records retained the largest market share even when new formats such as the compact cassette were mass-marketed. By the 1980s, digital media, in the form of the compact disc, had gained a larger market share, and the record left the mainstream in 1991. Since the 1990s, records con ...

Sound Recording And Reproduction
Sound recording and reproduction is the electrical, mechanical, electronic, or digital inscription and re-creation of sound waves, such as spoken voice, singing, instrumental music, or sound effects. The two main classes of sound recording technology are analog recording and digital recording. Sound recording is the transcription of invisible vibrations in air onto a storage medium such as a phonograph disc. The process is reversed in sound reproduction, and the variations stored on the medium are transformed back into sound waves. Acoustic analog recording is achieved by a microphone diaphragm that senses changes in atmospheric pressure caused by acoustic sound waves and records them as a mechanical representation of the sound waves on a medium such as a phonograph record (in which a stylus cuts grooves on a record). In magnetic tape recording, the sound waves vibrate the microphone diaphragm and are converted into a varying electric current, which is then converted to ...

Western Electric
The Western Electric Company was an American electrical engineering and manufacturing company officially founded in 1869. A wholly owned subsidiary of American Telephone & Telegraph for most of its lifespan, it served as the primary equipment manufacturer, supplier, and purchasing agent for the Bell System from 1881 to 1984 when it was dismantled. The company was responsible for many technological innovations as well as developments in industrial management. History In 1856, George Shawk, a craftsman and telegraph maker, purchased an electrical engineering business in Cleveland, Ohio. In January, 1869, Shawk had partnered with Enos M. Barton in the former Western Union repair shop of Cleveland, to manufacture burglar, fire alarms, and other electrical items. Both men were former Western Union employees. Shawk, was the Cleveland shop foreman and Barton, was a Rochester, New York telegrapher. During this Shawk and Barton partnership, one customer was an inventor sourcing parts an ...

Autograph Records
Autograph Records was an American record label in the 1920s owned by Marsh Laboratories of Chicago, Illinois, which was owned by Orlando R. Marsh, an electrical engineer. Marsh made recordings by his own experimental methods. Autograph was the first U.S. record label to release recordings made electrically with microphones, as opposed to the acoustical or mechanical method that was more commonly used.Columbia Graphophone marketed electrical 12-inch in early 20s. According to author Brian Rust, Marsh's first electrical records were made in 1924.Rust, Brian. "Autograph, a glimpse into the past." ''Storyville'' 1972; 40: 124-126. Organ music It was reported in ''Time'' on April 28, 1923, that a device invented by Marsh was successfully used to make a recording of organ music, until then considered impossible. The article stated that Pietro Yon from New York City played his organ composition "Jesu Bambino" in Marsh's Chicago laboratory, and that the reproduction was described as exce ...

Columbia Records
Columbia Records is an American record label owned by Sony Music, Sony Music Entertainment, a subsidiary of Sony Corporation of America, the North American division of Japanese Conglomerate (company), conglomerate Sony.

Radio
Radio is the technology of signaling and communicating using radio waves. Radio waves are electromagnetic waves of frequency between 30 hertz (Hz) and 300 gigahertz (GHz). They are generated by an electronic device called a transmitter connected to an antenna which radiates the waves, and received by another antenna connected to a radio receiver. Radio is very widely used in modern technology, in radio communication, radar, radio navigation, remote control, remote sensing, and other applications. In radio communication, used in radio and television broadcasting, cell phones, two-way radios, wireless networking, and satellite communication, among numerous other uses, radio waves are used to carry information across space from a transmitter to a receiver, by modulating the radio signal (impressing an information signal on the radio wave by varying some aspect of the wave) in the transmitter. In radar, used to locate and track objects like aircraft, ships, spacecraf ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

John Philip Sousa
John Philip Sousa ( ; November 6, 1854 – March 6, 1932) was an American composer and conductor of the late Romantic era known primarily for American military marches. He is known as "The March King" or the "American March King", to distinguish him from his British counterpart Kenneth J. Alford. Among his best-known marches are "The Stars and Stripes Forever" (National March of the United States of America), "Semper Fidelis" (official march of the United States Marine Corps), " The Liberty Bell", "The Thunderer", and "The Washington Post". Sousa began his career playing violin and studying music theory and composition under John Esputa and George Felix Benkert. His father enlisted him in the United States Marine Band as an apprentice in 1868. He left the band in 1875, and over the next five years, he performed as a violinist and learned to conduct. In 1880 he rejoined the Marine Band, and he served there for 12 years as director, after which he was hired to conduct a ban ...

Wanamaker's
John Wanamaker Department Store was one of the first department stores in the United States. Founded by John Wanamaker in Philadelphia, it was influential in the development of the retail industry including as the first store to use price tags. At its zenith in the early 20th century, Wanamaker's also had a store in New York City at Broadway and Ninth Street. Both employed extremely large staffs. By the end of the 20th century, there were 16 Wanamaker's outlets, but after years of change the chain was bought by Albert Taubman, and added to his previous purchase of Woodward & Lothrop, the Washington, D.C., department store. In 1994, Woodies, as it was known, filed for bankruptcy. The assets of Woodies were purchased by the May Company Department Stores and JCPenney. In 1995, Wanamaker's transitioned to Hecht's, one of the May Company brands. In 2006, Macy's Center City became the occupant of the former Philadelphia Wanamaker's Department Store, which is now a National Historic ...
