Plot summary
Tom and his father are arguing about Tom's latest idea, a photo telephone. Mr. Swift is adamant that the idea will not work, but Tom has some ideas in mind, and refuses to back down. Tom read about a recent news event where a photograph was transmitted over telegraph lines, and there is no functional difference between the wires used for a telephone to those used in telegraphs.
In the meantime, some shady occurrences are happening in the neighborhood. Tom and Ned are almost run over by a speeding motor boat, operated by a con-artist known as Shallock Peters. The feud between Mr. Peters and Tom begins when Mr. Peters refuses to acknowledge the accident. The animosity between the two only grows deeper as Mr. Peters tries to buy Tom out of some of his inventions, under the guise of making a profit. Tom refuses to allow anyone other than himself permissions to his patents, and this infuriates Mr. Peters. Later, Tom learns that his good friend, Mr. Damon, is having serious financial troubles. As the plot gets thicker and thicker, one of Tom's airships is stolen, and then Mr. Damon unexpectedly disappears. All this while Tom is desperately trying to get his latest invention working.
Fax, sometimes called telecopying or telefax, is the telephonic transmission of scanned printed material, normally to a telephone number connected to a printer or other output device. The original document is scanned with a fax machine, which processes the contents as a single fixed graphic image, converting it into a bitmap, and then transmitting it through the telephone system in the form of audio-frequency tones. The receiving fax machine interprets the tones and reconstructs the image, printing a paper copy. Early systems used direct conversions of image darkness to audio tone in a continuous or analog manner. Since the 1980s, most machines transmit an audio-encoded digital representation of the page, using data compression to more quickly transmit areas that are all-white or all-black.
A telephone is a telecommunications device that permits two or more users to conduct a conversation when they are too far apart to be easily heard directly. A telephone converts sound, typically and most efficiently the human voice, into electronic signals that are transmitted via cables and other communication channels to another telephone which reproduces the sound to the receiving user. The term is derived from Greek: τῆλε and φωνή, together meaning distant voice. A common short form of the term is phone, which came into use early in the telephone's history. Nowadays, phones are almost always in the form of smartphones or mobile phones, due to technological convergence.
Telegraphy is the long-distance transmission of messages where the sender uses symbolic codes, known to the recipient, rather than a physical exchange of an object bearing the message. Thus flag semaphore is a method of telegraphy, whereas pigeon post is not. Ancient signalling systems, although sometimes quite extensive and sophisticated as in China, were generally not capable of transmitting arbitrary text messages. Possible messages were fixed and predetermined, so such systems are thus not true telegraphs.
Tom Swift is the main character of six series of American juvenile science fiction and adventure novels that emphasize science, invention, and technology. Inaugurated in 1910, the sequence of series comprises more than 100 volumes. The first Tom Swift – later, Tom Swift Sr. – was created by Edward Stratemeyer, the founder of the Stratemeyer Syndicate, a book packaging firm. Tom's adventures have been written by various ghostwriters, beginning with Howard Garis. Most of the books are credited to the collective pseudonym "Victor Appleton". The 33 volumes of the second series use the pseudonym Victor Appleton II for the author. For this series, and some later ones, the main character is "Tom Swift Jr." New titles have been published again from 2019 after a gap of about ten years, roughly the time that has passed before every resumption. Most of the series emphasized Tom's inventions. The books generally describe the effects of science and technology as wholly beneficial, and the role of the inventor in society as admirable and heroic.
Johann Philipp Reis was a self-taught German scientist and inventor. In 1861, he constructed the first make-and-break telephone, today called the Reis telephone. It was the first device to transmit a voice via electronic signals and for that the first modern telephone. Reis also coined the term.
The telautograph is an ancestor of the modern fax machine. It transmits electrical signals representing the position of a pen or tracer at the sending station to repeating mechanisms attached to a pen at the receiving station, thus reproducing at the receiving station a drawing, writing, or signature made by the sender. It was the first such device to transmit drawings to a stationary sheet of paper; previous inventions in Europe had used a constantly moving strip of paper to make such transmissions and the pen could not be lifted between words. Surprisingly, at least from a modern perspective, some early telautographs used digital/pulse-based transmission while later more successful devices reverted to analog signaling.
Antonio Santi Giuseppe Meucci was an Italian inventor and an associate of Giuseppe Garibaldi, a major political figure in the history of Italy. Meucci is best known for developing a voice-communication apparatus that several sources credit as the first telephone.
Elisha Gray was an American electrical engineer who co-founded the Western Electric Manufacturing Company. Gray is best known for his development of a telephone prototype in 1876 in Highland Park, Illinois. Some recent authors have argued that Gray should be considered the true inventor of the telephone because Alexander Graham Bell allegedly stole the idea of the liquid transmitter from him. Although Gray had been using liquid transmitters in his telephone experiments for more than two years previously, Bell's telephone patent was upheld in numerous court decisions.
Nathan Beverly Stubblefield was an American inventor best known for his wireless telephone work. Self-described as a "practical farmer, fruit grower and electrician", he received widespread attention in early 1902 when he gave a series of public demonstrations of a battery-operated wireless telephone, which could be transported to different locations and used on mobile platforms such as boats. While this initial design employed conduction, in 1908 he received a U.S. patent for a wireless telephone system that used magnetic induction. However, he was ultimately unsuccessful in commercializing his inventions. He later went into seclusion, and died alone in 1928.
This timeline of the telephone covers landline, radio, and cellular telephony technologies and provides many important dates in the history of the telephone.
The invention of the telephone was the culmination of work done by more than one individual, and led to an array of lawsuits relating to the patent claims of several individuals and numerous companies.
Innocenzo Vincenzo Bartolomeo Luigi Carlo Manzetti was an Italian inventor born in Aosta. Following his primary school studies he went to the Jesuit-run Saint Bénin Boarding School and then on to Turin where he was awarded a diploma in land surveying before returning to Aosta.
Archibald Montgomery Low developed the first powered drone aircraft. He was an English consulting engineer, research physicist and inventor, and author of more than 40 books.
The Elisha Gray and Alexander Graham Bell controversy concerns the question of whether Gray and Bell invented the telephone independently. This issue is narrower than the question of who deserves credit for inventing the telephone, for which there are several claimants.
This history of the telephone chronicles the development of the electrical telephone, and includes a brief overview of its predecessors. The first telephone patent was granted to Alexander Graham Bell in 1869.
Giovanni Caselli was an Italian priest, inventor, and physicist. He studied electricity and magnetism as a child which led to his invention of the pantelegraph, the forerunner of the fax machine. The world's first practical operating facsimile machine ("fax") system put into use was by Caselli. He had worldwide patents on his system. His technology idea was further developed into today's analog television.
Tom Swift in the City of Gold, or, or, Marvelous Adventures Underground, is Volume 11 in the original Tom Swift novel series published by Grosset & Dunlap.
Tom Swift and His Giant Cannon, or, The Longest Shots on Record, is Volume 16 in the original Tom Swift novel series published by Grosset & Dunlap.
The Story of Alexander Graham Bell is a somewhat fictionalized 1939 biographical film of the famous inventor. It was filmed in black-and-white and released by Twentieth Century-Fox. The film stars Don Ameche as Bell and Loretta Young as Mabel, his wife, who contracted scarlet fever at an early age and became deaf.
Henry Sutton was an Australian designer, engineer, and inventor credited with contributions to early developments in electricity, aviation, wireless communication, photography and telephony.
