The Biography and Inventions of Inventor Thomas Edison

Thomas Alva Edison was born on February 11, 1847, in Milan, Ohio; the seventh and last child of Samuel and Nancy Edison. When Edison was seven his family moved to Port Huron, Michigan. Edison lived here until he struck out on his own at the age of sixteen. Edison had very little formal education as a child, attending school only for a few months. He was taught reading, writing, and arithmetic by his mother, but was always a very curious child and taught himself much by reading on his own. This belief in self-improvement remained throughout his life. Work as a Telegrapher Edison began working at an early age, as most boys did at the time. At thirteen he took a job as a newsboy, selling newspapers and candy on the local railroad that ran through Port Huron to Detroit. He seems to have spent much of his free time reading scientific, and technical books, and also had the opportunity at this time to learn how to operate a telegraph. By the time he was sixteen, Edison was proficient enough to work as a telegrapher full time. First Patent The development of the telegraph was the first step in the communication revolution, and the telegraph industry expanded rapidly in the second half of the 19th century. This rapid growth gave Edison and others like him a chance to travel, see the country, and gain experience. Edison worked in a number of cities throughout the United States before arriving in Boston in 1868. Here Edison began to change his profession from telegrapher to inventor. He received his first patent on an electric vote recorder, a device intended for use by elected bodies such as Congress to speed the voting process. This invention was a commercial failure. Edison resolved that in the future he would only invent things that he was certain the public would want. Marriage to Mary Stilwell Edison moved to New York City in 1869. He continued to work on inventions related to the telegraph, and developed his first successful invention, an improved stock ticker called the Universal Stock Printer. For this and some related inventions, Edison was paid $40,000. This gave Edison the money he needed to set up his first small laboratory and manufacturing facility in Newark, New Jersey in 1871. During the next five years, Edison worked in Newark inventing and manufacturing devices that greatly improved the speed and efficiency of the telegraph. He also found time to get married to Mary Stilwell and start a family. Move to Menlo Park In 1876 Edison sold all his Newark manufacturing concerns and moved his family and staff of assistants to the small village of Menlo Park, twenty-five miles southwest of New York City. Edison established a new facility containing all the equipment necessary to work on any invention. This research and development laboratory was the first of its kind anywhere; the model for later, modern facilities such as Bell Laboratories, this is sometimes considered to be Edisons greatest invention. Here Edison began to change the world. The first great invention developed by Edison in Menlo Park was the tin foil phonograph. The first machine that could record and reproduce sound created a sensation and brought Edison international fame. Edison toured the country with the tin foil phonograph  and was invited to the White House to demonstrate it to President Rutherford B. Hayes in April 1878. Edison next undertook his greatest challenge, the development of a practical incandescent, electric light. The idea of electric lighting was not new, and a number of people had worked on, and even developed forms of electric lighting. But up to that time, nothing had been developed that was remotely practical for home use. Edisons eventual achievement was inventing not just an incandescent electric light, but also an electric lighting system that contained all the elements necessary to make the incandescent light practical, safe, and economical.    Thomas Edison Founds an Industry Based on Electricity After one and a half years of work, success was achieved when an incandescent lamp with a filament of carbonized sewing thread burned for thirteen and a half hours. The first public demonstration of the Edisons incandescent lighting system was in December 1879, when the Menlo Park laboratory complex was electrically lighted. Edison spent the next several years creating the electric industry. In September 1882, the first commercial power station, located on Pearl Street in lower Manhattan, went into operation providing light and power to customers in a one square mile area; the electric age had begun.    Fame Wealth The success of his electric light brought Edison to new heights of fame and wealth, as electricity spread around the world. Edisons various electric companies continued to grow until in 1889 they were brought together to form Edison General Electric. Despite the use of Edison in the company title however, Edison never controlled this company. The tremendous amount of capital needed to develop the incandescent lighting industry had necessitated the involvement of investment bankers such as J.P. Morgan. When Edison General Electric merged with its leading competitor Thompson-Houston in 1892, Edison was dropped from the name, and the company became simply General Electric. Marriage to Mina Miller This period of success was marred by the death of Edisons wife Mary in 1884. Edisons involvement in the business end of the electric industry had caused Edison to spend less time in Menlo Park. After Marys death, Edison was there even less, living instead in New York City with his three children. A year later, while vacationing at a friends house in New England, Edison met Mina Miller and fell in love. The couple was married in February 1886 and moved to West Orange, New Jersey where Edison had purchased an estate, Glenmont, for his bride. Thomas Edison lived here with Mina until his death.    New Laboratory Factories When Edison moved to West Orange, he was doing experimental work in makeshift facilities in his electric lamp factory in nearby Harrison, New Jersey. A few months after his marriage, however, Edison decided to build a new laboratory in West Orange itself, less than a mile from his home. Edison possessed the both the resources and experience by this time to build, the best equipped and largest laboratory extant and the facilities superior to any other for rapid and cheap development of an invention. The new laboratory complex consisting of five buildings opened in November 1887. A three story main laboratory building contained a power plant, machine shops, stock rooms, experimental rooms and a large library. Four smaller one story buildings built perpendicular to the main building contained a physics lab, chemistry lab, metallurgy lab, pattern shop, and chemical storage. The large size of the laboratory not only allowed Edison to work on any sort of project, but also allowed him to work on as many as ten or twenty projects at once. Facilities were added to the laboratory or modified to meet Edisons changing needs as he continued to work in this complex until his death in 1931. Over the years, factories to manufacture Edison inventions were built around the laboratory. The entire laboratory and factory complex eventually covered more than twenty acres and employed 10,000 people at its peak during World War One (1914-1918). After opening the new laboratory, Edison began to work on the phonograph again, having set the project aside to develop the electric light in the late 1870s. By the 1890s, Edison began to manufacture phonographs for both home, and business use. Like the electric light, Edison developed everything needed to have a phonograph work, including records to play, equipment to record the records, and equipment to manufacture the records and the machines. In the process of making the phonograph practical, Edison created the recording industry. The development and improvement of the phonograph was an ongoing project, continuing almost until Edisons death.    The Movies While working on the phonograph, Edison began working on a device that, does for the eye what the phonograph does for the ear, this was to become motion pictures. Edison first demonstrated motion pictures in 1891, and began commercial production of movies two years later in a peculiar looking structure, built on the laboratory grounds, known as the Black Maria. Like the electric light and phonograph before it, Edison developed a complete system, developing everything needed to both film and show motion pictures. Edisons initial work in motion pictures was pioneering and original. However, many people became interested in this third new industry Edison created, and worked to further improve on Edisons early motion picture work. There were therefore many contributors to the swift development of motion pictures beyond the early work of Edison. By the late 1890s, a thriving new industry was firmly established, and by 1918 the industry had become so competitive that Edison got out of the movie business all together.    Even a Genius Can have a Bad Day 1890sgreatest failure    A Profitable Product alkaline battery . By 1911, Thomas Edison had built a vast industrial operation in West Orange. Numerous factories had been built through the years around the original laboratory, and the staff of the entire complex had grown into the thousands. To better manage operations, Edison brought all the companies he had started to make his inventions together into one corporation, Thomas A. Edison Incorporated, with Edison as president and chairman. Aging Gracefully In the 1915, Edison was asked to head the Naval Consulting Board. With the United States inching closer towards the involvement in World War One, the Naval Consulting Board was an attempt to organize the talents of the leading scientists and inventors in the United States for the benefit of the American armed forces. Edison favored preparedness, and accepted the appointment. The Board did not make a notable contribution to the final allied victory, but did serve as a precedent for future successful cooperation between scientists, inventors and the United States military. During the war, at age seventy, Edison spent several months on Long Island Sound in a borrowed navy vessel experimenting on techniques for detecting submarines. Honoring a Lifetime of Achievement Edisons role in life began to change from inventor and industrialist to cultural icon, a symbol of American ingenuity, and a real life Horatio Alger story. In 1928, in recognition of a lifetime of achievement, the United States Congress voted Edison a special Medal of Honor. In 1929 the nation celebrated the golden jubilee of the incandescent light. The celebration culminated at a banquet honoring Edison given by Henry Ford at Greenfield Village, Fords new American history museum, which included a complete restoration of the Menlo Park Laboratory. Attendees included President Herbert Hoover and many of the leading American scientists and inventors. The last experimental work of Edisons life was done at the request of Edisons good friends Henry Ford, and Harvey Firestone in the late 1920s. They asked Edison to find an alternative source of rubber for use in automobile tires. The natural rubber used for tires up to that time came from the rubber tree, which does not grow in the United States. Crude rubber had to be imported and was becoming increasingly expensive. With his customary energy and thoroughness, Edison tested thousands of different plants to find a suitable substitute, eventually finding a type of Goldenrod weed that could produce enough rubber to be feasible. Edison was still working on this at the time of his death. A Great Man Dies During the last two years of his life Edison was in increasingly poor health. Edison spent more time away from the laboratory, working instead at Glenmont. Trips to the family vacation home in Fort Myers, Florida became longer. Edison was past eighty and suffering from a number of ailments. In August 1931 Edison collapsed at Glenmont. Essentially house bound from that point, Edison steadily declined until at 3:21 am on October 18, 1931 the great man died.

The basic trade-off here is between committing to an order from a lower price or waiting for a high price to arrive later on. The risks in such situation are spoilage and spill. Spoilage occurs when capacity is wasted because demand from high price doesn’t materialize. Spill occurs if higher price segments have to be refused because capacity has already been committed to lower price segment. u If a supplier serves numerous customer segments with a fixed benefit, the provider can improve revenues by setting different prices for eac h segment u Prices must be set with barriers such that the segment willing to pay more is not able to pay the lower price u The amount of the asset set aside for the higher price segment is such that the expected marginal revenue from the higher priced segment equals the price of the lower price segment Perishable Assets There are two revenue management tactics used for perishable assets: ⇠¨ Vary price over time to maximize expected revenue ⇠¨ Overbook sales of the assets to account for cancellations The first tactic is appropriate for assets such as fashion wear that have clear date beyond which they lose a lot of their value; clothing designed for a particular season loses its value whenShow MoreRelatedWalmart, The Largest Public Service Company1342 Words   |  6 Pagesoperations, the company garnered revenues of $700,000 in sales.

Masaccio, Donatello, and Brunelleschi Renaissance Pioneers Essay Example For Students

Masaccio, Donatello, and Brunelleschi Renaissance Pioneers Essay The pioneer generation of the Renaissance artists was generally considered to be the painter Mosaic, the sculptor Donated, and the architect Brucellosis. They applied Humanist thinking to art by using the styles of the classical world, instead of their immediate past, to depict the world around them in a naturalistic manner. The idealized statuary of classical antiquity served as their models, while in architecture the classical orders were applied to Renaissance buildings. They also extended their understanding of light and shadow, of perspective and anatomy. Mosaic was a key Florentine painter of the early Renaissance whose great work, the frescoes in the Britannica Chapel of the Church of Santa Maria del Carmine in Florence, remained influential throughout the Renaissance. He learned about mathematical proportion from his friend Brucellosis, which was crucial to his revival of the principles of scientific perspective. From Donated he gained knowledge of the classical styles of art that led him away from the prevailing Gothic style of painting. He inaugurated a new naturalistic approach to painting that as concerned less with flat surfaces and ornamentation than with simplicity and the illusion of three dimensions. The fresco series he painted for the Britannica Chapel in about 1427, illustrates one of his greatest innovations, the use of light to define the human body and its draperies. In these frescoes, rather than bathing his scenes in flat uniform light that was common to most current painting techniques, he painted them as if they were illuminated from a single source of light (in this case, the actual chapel window). This created a unique mix of light and shadow that gave them a natural, realistic quality hat was unknown in the art that was produced in his day. He put into practice Brutishnesss theories about how to project depth beyond a flat painted surface, employing the lines of painted architecture to create a convincing illusion of space. Donated, one of the greatest of all Italian Renaissance artists, was a master of sculpture in both marble and bronze. He had a more detailed and wide-ranging knowledge of ancient sculpture than any other artist of his day. When he was 17 years old, he assisted the noted sculptor Lorenz Gibber in constructing and escorting the famous bronze doors of the baptistery of San Giovanni in Florence. In his bronze David (c. 1430); Donated created probably the first freestanding bronze nude since antiquity. The adolescents slim, sinuous lines, and his nudity, which was emphasized by his hat, symbolized the Renaissance ideal of physical grace and beauty. Used the sole surviving ancient Roman equestrian statue, the Marcus Aurelias, as a model, and reinvented the mode of presenting a great general. He elevated the group on a high base, gave the rider an alert and commanding energy, and made the eider and horse convincingly proportionate to each other. In a later period, Donated broke away from classical influences and emphasized realism and the portrayal of character and dramatic action in his work. A notable example of his sculpture of this period is the wood sculpture of Mary Magdalene (c. 1454). He used a powerful realism that gives his statues a distinct look. Donated had an immense impact on the art and the artists of the Renaissance. He invented the shallow relief technique in which the sculpture seems deep but is actually done on a very shallow plane. He seemed to be equally at home this type of sculpture as his freestanding statues. He also make much use wood as well as marble and bronze. Donated characterized his figures as individuals and was also a major influence on the development of realism in Italian painting, Brutishnesss revival of classical forms and his championing of an architecture based on mathematics, proportion, and perspective make him a key artistic figure in the transition from the Middle Ages to the modern era. He was trained as a sculptor and goldsmith in a Florentine workshop. He spent overall years in Rome studying sculpture and measuring ancient buildings in Rome to understand the harmony of classical proportions in architecture. .u352acfa095aee416d631a9b009fdf9c1 , .u352acfa095aee416d631a9b009fdf9c1 .postImageUrl , .u352acfa095aee416d631a9b009fdf9c1 .centered-text-area { min-height: 80px; position: relative; } .u352acfa095aee416d631a9b009fdf9c1 , .u352acfa095aee416d631a9b009fdf9c1:hover , .u352acfa095aee416d631a9b009fdf9c1:visited , .u352acfa095aee416d631a9b009fdf9c1:active { border:0!important; } .u352acfa095aee416d631a9b009fdf9c1 .clearfix:after { content: ""; display: table; clear: both; } .u352acfa095aee416d631a9b009fdf9c1 { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .u352acfa095aee416d631a9b009fdf9c1:active , .u352acfa095aee416d631a9b009fdf9c1:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .u352acfa095aee416d631a9b009fdf9c1 .centered-text-area { width: 100%; position: relative ; } .u352acfa095aee416d631a9b009fdf9c1 .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .u352acfa095aee416d631a9b009fdf9c1 .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .u352acfa095aee416d631a9b009fdf9c1 .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .u352acfa095aee416d631a9b009fdf9c1:hover .ctaButton { background-color: #34495E!important; } .u352acfa095aee416d631a9b009fdf9c1 .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .u352acfa095aee416d631a9b009fdf9c1 .u352acfa095aee416d631a9b009fdf9c1-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .u352acfa095aee416d631a9b009fdf9c1:after { content: ""; display: block; clear: both; } READ: Harlem Renaissance by Nathan Irvin Huggins EssayIn 1418 received the commission to execute the dome of the unfinished Gothic Cathedral of Florence the Doom. The dome, a great innovation both artistically and technically, consists of two octagonal vaults, one inside the other. Brucellosis made a design feature of the necessary eight ribs of the vault, carrying them over to the exterior of the dome, where they provide the framework for the domes decorative elements, which also include architectural relief, circular windows, and a beautifully proportioned cupola. This was the first time that a dome created the same strong effect on the exterior as it did on the interior. In other buildings: the Medici Church of San Lorenz, and the Esplanade dogleg Innocent; Brucellosis devised an austere, geometric style that was inspired by the art of ancient Rome. It was completely different from the emotional, elaborate Gothic style that was still popular in his time. Brutishnesss style emphasized mathematical rigor in its use of straight lines, flat planes, and cubic spaces. This wall architecture, with its flat facades, set the tone for many of the later buildings of the Florentine Renaissance. Later in his career he moved away from this linear, geometric style to a somewhat more sculptural style. For example, the interior of one of his buildings was formed not by his usual flat walls, but by massive niches that opened from a central octagon. Baroque. His influence on his contemporaries and immediate followers was very strong and has been felt even in the 20th century, when modern architects came to revere him as the first great exponent of rational architecture.
