Eventually, he began to market and sell the machines and cylinder records, reverting again to using wax. Even though cylinders produced better-quality sound, the early discs had a big advantage in that they could fit four minutes of music, compared to the two minutes that could fit on a cylinder. But Edison adjusted and his company became a thriving early movie studio, churning out scores of silent films between the s and , when it shut down production.
When the automobile was developed in the late s, electric vehicles were more popular than those equipped with gasoline-burning internal combustion engines. Edison decided to take on the challenge of inventing a lighter, more dependable and more powerful battery. After conducting extensive research and the embarrassing flop of an early design, Edison came up with a reliable alkaline battery, and in began production of it.

His interest in sound technology was deep-rooted and personal, as both his wife and mother were deaf. Italian inventor and engineer Guglielmo Marconi developed, demonstrated and marketed the first successful long-distance wireless telegraph and in broadcast the first transatlantic radio signal.
Thomas Paine was an England-born political philosopher and writer who supported revolutionary causes in America and Europe. Developed in the s and s by Samuel Morse and other inventors, the telegraph revolutionized long-distance communication. It worked by transmitting electrical signals over a wire laid between stations. In addition to helping invent the telegraph, Samuel Morse In , Connecticut-born gun manufacturer Samuel Colt received a U.
Colt founded a company to manufacture his revolving-cylinder pistol; however, sales were slow and the Thomas Jefferson , author of the Declaration of Independence and the third U. Wilbur and Orville Wright were American inventors and pioneers of aviation. In the Wright brothers achieved the first powered, sustained and controlled airplane flight; they surpassed their own milestone two years later when they built and flew the first fully practical Live TV.
This Day In History. Including his foreign patents filed in other countries, his total is 2, Some of Edison's most famous patents are the light bulb, phonograph, motion picture camera, and storage battery.
However, what makes Edison such an important figure in the world of invention isn't the success of few patents, but instead is the depth and breadth of his work. His patents can be grouped into roughly eight categories:.
Edison appears to have had two great periods where his patent applications soared, and ; but throughout his career there was a steady flow of ideas and concepts for new products. He also meticulously recorded his work in 4, notebooks to protect his intellectual property, influencing generations of inventors and entrepreneurs who would follow in his footsteps.
At West Orange, Edison combined invention and entrepreneurial activities, demonstrating how invention had grown from its cottage industry roots to a full-scale commercial enterprise, destined to be an essential part of modern business. Edison Industries, Inc. Patent 91, — June 22, — Improvement in Printing-Telegraphs. Patent , — August 27, — Improvement in Electro-Magnets.
Patent , — August 12, — Improvement in Relay-Magnets. Patent , — September 23, — Improvement in Galvanic Batteries. Patent , — February 24, — Improvement in Duplex Telegraphs. Patent , — March 26, — Improvement in Speaking-Machines. Patent , — May 7, — Improvement in Perforating-Pens.
Patent , — December 10, — Improvement in Vocal Engines. He executed his first patent for his Electrographic Vote-Recorder on October 13, , at the age of His last patent was for an apparatus for holding objects during the electroplating process. Edison became embroiled in a longstanding rivalry with Nikola Tesla , an engineering visionary with academic training who worked with Edison's company for a time.
The two parted ways in and would publicly clash in the " War of the Currents " about the use of direct current electricity, which Edison favored, vs. Tesla then entered into a partnership with George Westinghouse, an Edison competitor, resulting in a major business feud over electrical power.
One of the unusual - and cruel - methods Edison used to convince people of the dangers of alternating current was through public demonstrations where animals were electrocuted. One of the most infamous of these shows was the electrocution of a circus elephant named Topsy on New York's Coney Island.
He was 84 years old. Many communities and corporations throughout the world dimmed their lights or briefly turned off their electrical power to commemorate his passing. Edison's career was the quintessential rags-to-riches success story that made him a folk hero in America.
