Reginald A Fessenden


Reginald Aubrey Fessenden (born October 6, 1866 - died July 22, 1932 at age 65 years) is one of the many people who contributed to the development of radio technology. He is co-inventor of radio, U.S. physicist, engineer, and professor of physics. Fessenden was born on October 6, 1866 in East Bolton, Quebec, Canada. He has successfully created 500 inventions, including the alternator, detectors, heterodin, fathometer and drive an electric turbo for battleships. Fessenden spent his education at Trinity College in Port Hope, Ontario and at Bishop's University in Lennoxville, Quebec. Her career began with a teacher and principal at Whitney Institute. During the care of the school, he did experiments in the field of electrical and chemical. Then he moved to New York, United States and apply for jobs in Edison laboratory at Orange, New York. He was a chief part in the field of chemistry.


Alternator is a tool to generate electricity and produce alternating current. Alternator are electromechanical devices that convert mechanical energy into electrical energy of alternating current. In principle, an electric generator of alternating current is called the alternator, but the generally accepted sense of the power generator on the vehicle engine. Alternator in power plant steam turbine driven by the so-called turbo-alternator. With the alternator has been encouraging the creation of a radio telephone.


The detector is a tool to convert alternating current into direct current. Meanwhile, Heterodin is a tool to change the radio frequency so the frequency is easily adjustable and can be strengthened. Fessenden classical education had given him only a limited number of scientific and technical training. Interested in improving skills in the fields of electricity, he moved to New York City in 1886, with hopes of getting a job with the famous inventor, Thomas Edison. As recounted in his autobiography News Radio 1925, the business-in the beginning was rejected the first application Fessenden wrote, "Do not know anything about electricity, but can learn pretty quickly," which Edison replied, "Have enough men now who do not know of electricity. "However, Fessenden last, and before the end of the year was employed for semi-skilled positions as assistant tester Edison Machine Works, the laying of underground electric power in New York City.


He quickly proved its worth, and received a series of promotions, with increasing responsibility for the project. In late 1886, Fessenden began working directly for Thomas Edison at the inventor of a new laboratory in West Orange, New Jersey. A variety of projects including work in solving problems in chemistry, metallurgy, and electricity. However, in 1890, facing financial problems, Edison was forced to lay off most of the lab employees, including Fessenden. Taking advantage of recent practical experience, Fessenden was able to find a position with a series of manufacturing companies. Subsequently, in 1892, he accepted an appointment as professor to the newly formed department of Engineering in Electrical Purdue University in West Lafayette, Indiana at that time he helped Westinghouse Corporation install the lighting for the 1893 World Colombian Exposition in Chicago. Shortly thereafter in the same year, George Westinghouse personally recruited Fessenden for the newly created position of chairman of the department of Electrical Engineering at the University of Western Pennsylvania, renamed the University of Pittsburgh in 1908.



Fessenden began experimenting with a wireless telephone in 1898, by 1899 he had a functioning system of wireless communication between Pittsburgh and Allegheny City. It was decided to try to build a transatlantic service radiotelegraph, and, in January, 1906, employing his rotary-spark transmitters, Fessenden made the first successful two-way transatlantic transmission, exchanging Morse code messages between the station was built at Brant Rock and identical to the built in Machrihanish, Scotland. (Marconi was only one direction of transmission at this time.) However, the transmitter can not bridge this distance during daylight hours or in the summer, so the work was postponed until later this year. Then, on December 6, 1906, "due to the carelessness of one of the contractors used in the shift of some of the cable support", Machrihanish radio tower collapsed, abruptly ending the transatlantic work before it can ever go into commercial service. Although Fessenden radio halt after his dismissal from NESCO in 1911, he continued to work in other fields. In early 1904 he had helped engineer the Niagara Falls power plant to Hydro-Electric Power Commission of the newly formed Ontario.


However, his most extensive is in developing a type of sonar system, called Fessenden oscillator, for submarines to signal each other, as well as methods to locate icebergs, to help avoid another disaster like the sinking Titanic. At the outbreak of World War I, Fessenden volunteered services to the Canadian government and sent to London, England where he developed a device to detect enemy artillery and the other to look for enemy submarines. A common tinkerer, Fessenden eventually became the holder of more than 500 patents. He often can be found in rivers or lakes, floating on his back, a cigar sticking out of his mouth and a hat pulled down over his eyes.


At home she likes to lay on the carpet, the cat on his chest. In a state of relaxation, Fessenden could imagine, create and think the way to new ideas, including microfilm version, which helped him to keep a record of the compact, the project's discoveries and patents. He patented the basic ideas that lead to reflection seismology, an important technique for use in petroleum exploration. In 1915 he found a fathometer, a sonar device used to determine water depth for submerged objects by sound waves, which he won the Gold Medal at the 1929 Scientific American. Fessenden also received a patent for tracer bullets, paging, television apparatus, turbo electric drive for ships, and more. Upon completion of the lawsuit with RCA, Fessenden purchased a small real-called "Wistowe" in Bermuda.


He died there in 1932 and was interred in the cemetery of St. Mark Church on the island. Fessenden home at 45 Waban Hill Road in the village of Chestnut Hill in Newton, Massachusetts on the National Register of Historic Places and the U.S. National Historic Landmark. He bought the house in 1906 or earlier and have for the rest of his life.
