The Invention of the Radio
The invention of the radio has affected nearly every person on this planet. Not a single day goes by without coming in contact with this device at some time. The history of this instrument dates back to the late fifteen century. At that time the brightest scholars weren't even aware of the possibility that electricity, television waves, and electro-magnetic radiation surrounded there everyday work. Yet even at this early stage the potential of radio communication amazed those who could dream of its possibilities. The development of the wireless radio has shaped, and, in our darkest hours, helped to save the world we live in today. While the improvement of the radio would take nearly three centuries, the first live broadcast would be given Christmas Eve of 1905 in the town of Brant Rock, Massachusetts (Radio...pg1). The first documentation of research aiding to the development of the radio was recorded in the year 1600 by Sir William Gilbert. His work was in the area of magnetism, and he is credited with the implementation of the first two "Theories of Magnetism." This Englishman's most valuable work made the speculation that Earth itself was a huge magnet (Time...pg1). The next advancement of radio technology, also con
Throughout the seventeenth century many of the inventors working with radio were diligently trying to accomplish the same goal. The man who made the most progress towards that goal was Joseph Henry. His work involved the transformation of electronic pulses, known as oscillatory discharges, through open air waves (Time...pg2). While Henry was successful with his work, the true pioneer of the phenomena was Samuel Morse and his assistant, Alfred Vail. The original version of "Morse Code" was completed in the year 1851 (Time...pg2). The Morse Code worked by using a set series of predetermined codes for each letter of the alphabet. These codes in turn related to the tone heard through a speaker at the receiving end of the device. This original version of Morse Code, however, was not a wireless device; the understanding of wireless transformation of telegraph would not be discovered until the year 1865. Further inventions, completed almost entirely by one man, would only add to the already increasing range of the radio's power. Edwin Armstrong was the man responsible for these creations. Throughout the period of 1910 and 1933 Armstrong created the "Regenerative Circuit (1912), the Super-heterodyne Circuit (1918), the Super-regenerative Circuit (1922) and the complete FM System (1933) (Time...p)." Additional to the previous, was the "portable" radio finish in 1924, which was nearly half the size of a grown man! The use of radio for propaganda and public notification throughout WWI and WWII would hold a nation together during its most grueling periods. The potential of the radio for these types of public notice would not be fully realized until the end of WWI. This was mainly due to advancements in technology and cost reduction. On December 7, 1941 radio and America would go to war together for the fir
