A black and white photo of a man on a phone. Office of War Information Photograph
Summary
This image is one of the images made by photographers working in Stryker's unit as it existed in a succession of government agencies: the Farm Security Administration (1937-1942).
The photographs of the Farm Security Administration - Office of War Information Photograph Collection form an extensive pictorial record of American life between 1935 and 1944. This U.S. government photography project was headed for most of its existence by Roy E. Stryker, formerly an economics instructor at Columbia University, and employed such photographers as Walker Evans, Dorothea Lange, Russell Lee, Arthur Rothstein, Ben Shahn, Jack Delano, Marion Post Wolcott, Gordon Parks, John Vachon, and Carl Mydans.
The unit's main office was in Washington, D.C. The office distributed photographic equipment and film, drew up budgets, allocated travel funds, hired staff, developed, printed, and numbered most negatives, reviewed developed film, edited photographers' captions written in the field, and maintained files of negatives, prints, and captions.
Staff photographers were given specific subjects and/or geographic areas to cover. These field assignments often lasted several months. Rejected images were classified as "killed." In earlier phases of the project a hole was sometimes punched through the "killed" negatives; later, this practice was abandoned. The rejected images are usually near duplicates and alternate views of a printed negative.
The invention of the telephone still remains a confusing morass of claims and counterclaims, which were not clarified by the huge mass of lawsuits to resolve the patent claims of commercial competitors. The Bell and Edison patents, however, dominated telephone technology and were upheld by court decisions in the United States. Bell has most often been credited as the inventor of the first practical telephone. Alexander Graham Bell was the first to patent the telephone as an "apparatus for transmitting vocal or other sounds telegraphically". The telephone exchange was an idea of the Hungarian engineer Tivadar Puskás (1844 - 1893) in 1876, while he was working for Thomas Edison on a telegraph exchange. Before the invention of the telephone switchboard, pairs of telephones were connected directly with each other, practically functioned as an intercom. Although telephones devices were in use before the invention of the telephone exchange, their success and economical operation would have been impossible with the schema and structure of the contemporary telegraph systems. A telephone exchange was operated manually by operators, or automatically by machine switching. It interconnects individual phone lines to make calls between them. The first commercial telephone exchange was opened at New Haven, Connecticut, with 21 subscribers on 28 January 1878, in a storefront of the Boardman Building in New Haven, Connecticut. George W. Coy designed and built the world's first switchboard for commercial use. The District Telephone Company of New Haven went into operation with only twenty-one subscribers, who paid $1.50 per month, a one-night price for a room in a city-center hotel. Coy was inspired by Alexander Graham Bell's lecture at the Skiff Opera House in New Haven on 27 April 1877. In Bell's lecture, during which a three-way telephone connection with Hartford and Middletown, Connecticut, was demonstrated, he first discussed the idea of a telephone exchange for the conduct of business and trade.
