Who invented radio

— Who Invented Radio? — With his newly created Tesla coils, the inventor soon discovered that he could transmit and receive powerful radio signals when they were tuned to resonate at the same frequency. When a coil is tuned to a signal of a particular frequency, it literally magnifies the incoming electrical energy through resonant action. By early 1895, Tesla was ready to transmit a signal 50 miles to West Point, New York... But in that same year, disaster struck. A building fire consumed Tesla's lab, destroying his work. The timing could not have been worse. In England, a young Italian experimenter named Guglielmo Marconi had been hard at work building a device for wireless telegraphy. The young Marconi had taken out the first wireless telegraphy patent in England in 1896. His device had only a two-circuit system, which some said could not transmit "across a pond." Later Marconi set up long-distance demonstrations, using a Tesla oscillator to transmit the signals across the English Channel. Tesla filed his own basic radio patent applications in 1897. They were granted in 1900. Marconi's first patent application in America, filed on November 10, 1900, was turned down. Marconi's revised applications over the next three years were repeatedly rejected because of the priority of Tesla and other inventors. The Patent Office made the following comment in 1903: Many of the claims are not patentable over Tesla patent numbers 645,576 and 649,621, of record, the amendment to overco...

Nikola Tesla and Guglielmo Marconi are the two main competitors for the accolade of inventing the radio. Inventor Tesla may have got there first as he demonstrated a wireless radio in St Louis, Missouri, in 1893. But Marconi got the very first wireless telegraphy patent in England in 1896. Tesla filed for patents for his basic radio in the United States a year later, and finally got his patent in 1900. The US Supreme Court made a decision to give the title of first patent to Tesla instead of Marconi in 1943. Marconi was the first person to transmit signals across the Atlantic, on December 1, 1901. Nathan Stubblefield was a contemporary of Tesla and Marconi, and also patented a wireless radio transmitter in 1908. They travel out in all directions at 300,000 kilometres per second (186,000 miles per second), the speed of light. In modern communications, radio waves are produced by currents in wires called antennas. But the first radio waves made deliberately were produced by electric current jumping through the air as a spark. Marconi flashed the first wireless signal across the English Channel in 1899, and the letter "S" was telegraphed back from England to Marconi in Newfoundland in 1901. In 1903, President Theodore Roosevelt and King Edward VII had a transatlantic conversation via a Marconi station in Massachusetts - although speech wasn’t tra...

History of Radio A young girl listening to the radio during the Golden Age of Radio, 1920s through end of WWII. In today's world, most people have either seen or have owned a radio. They are in homes and cars, and are a part of daily life for most people. Many inventors and researchers are responsible for the creation of the first radio. The development of the first successful radio in the 19th century required several stages of production. What is Radio? What is a radio, technically speaking? A radio is a device that uses the transmission and reception of electromagnetic waves of radio frequency to carry sound messages. The first radio was developed in the late 1800s. It took many years of research before radios became household items owned by the general public. What Year Was the Radio Invented? The creation of the first radio is very difficult to pinpoint. There were several scientists involved in the creation of the radio. The question of who invented radio and when radios were invented is complex, mainly because many people were involved in the process, and the creation spans a large amount of time. It is proven that the first wireless radio was invented in 1893 by The question of when the radio was invented is also is a difficult one to answer. Historians have recorded that the first communication sent over radio waves was sent by Guglielmo Marconi on December 12, 1901. This date is considered the radio invention date. Who Invented Radio? The invention of radio was a...

The invention of the telegraph and the telephone helped to lay the groundwork for the radio. All three have a lot in common, and wireless telegraphy was the original form of radio technology. The phrase “radio” can refer to either the electronic equipment we use to listen to music or the material that is played from it. In any case, it all began with the discovery of radio waves—electromagnetic waves that have the ability to transport music, speech, photos, and other data without impairing anyone’s hearing. Many gadgets rely on these waves, including The history of radio The story of radio begins with the work of a physicist named James Clerk Maxwell. In 1864, he published a paper that proposed the existence of electromagnetic waves. This was something that had never been seen before, and it was pure speculation. But in 1887, It wasn’t long before people started to experiment with radios, and by 1895 there were regular broadcasts being made in Europe. The first broadcasts in the United States were made in 1920, and radio quickly became a popular form of entertainment. In the early days, radio was used for a variety of purposes. It was a way to communicate with people who were far away, it was used to spread news and information, and it was even used for propaganda during World War II. But over time, radio has become primarily used for entertainment. There are now thousands of different radio stations that can be listened to anywhere in the world, and people use radios to l...

Hulton Archive/ Inventors around the world were churning out new and exciting inventions left and right in the years leading up to the 20th century. Scientific work in radio technology was heating up too. Two men in particular, Serbian-American scientist Nikola Tesla and Italian physicist Guglielmo Marconi went head-to-head in what would become the race to invent the After emigrating to the U.S. in 1884, Tesla invented the induction coil or Tesla coil, a device essential to sending and receiving radio waves and one the U.S. Patent Office would later say Marconi relied on for his work [source: Meanwhile, Marconi had been conducting his own experiments and in 1896, sent and received Morse code-based radio signals at distances spanning nearly 4 miles (6 kilometers) in England. That same year, he applied for, and was granted, the world's first patent in wireless telegraphy in England [source: Tesla applied for his first patents in radio work in 1897 in America. He also built and demonstrated a radio-controlled boat at Madison Square Garden in 1898. Here's where things get sticky. In 1900, the U.S. Patent Office granted Tesla patents 645,576 and 649,621, the fundamental design of the Tesla coils, on March 20 and May 15 respectively. Tesla's radio patents gave him ownership over one of the key necessities in radio communications. That same year, on Nov. 10, Marconi filed patent No. 7777, for tuned telegraphy. At first the patent office denied Marconi's applications on the ground...

Maxwell’s prediction was confirmed in 1887 by the German physicist Heinrich Hertz, who – incredibly – dismissed radio waves as “of no use whatsoever”. Fortunately, other scientists saw potential in the mysterious waves that could travel through air, solid walls or the vacuum of space. Among them were the British physicist Oliver Lodge and the Italian electrical engineer Guglielmo Marconi, who independently invented ways of turning electrical discharges into detectable signals. The two men were often locked in legal battles over patents, but Marconi is usually regarded as the ‘inventor’ of radio communication. That’s partly because he was the first to send simple radio signals across the Atlantic Ocean, a PR coup which led to international recognition, including a Nobel Prize.
