Nathan StubblefieldNathan B. Stubblefield was the son of a lawyer, Capt Billy Stubblefield, and he was an educator: Nathan Founded the "Telph-on-dlgreen" school in Murray, Kentucky. Telph-on-dlgreen is now the campus where Murray State University is located. Over one hundred ten years ago, the school Stubblefield operated at that site was called, "Nathan B. Stubblefield's Wireless Industrial School, or "Telph-on-dlgreen" ? "Yes" -- said the late Murray State Professor, Dr. Larry Joseph Hortin, Ph.D. -- "Today, Stubblefield's school, radio station, fruit orchards and watermelon patches used for atmospheric transmissions, is called Murray State University." Hortin was an advocate for the primacy of Stubblefield for many decades after the arrived at the campus to teach journalism in 1930. He led the fight to erect a monument to Stubblefield on the campus near where the inventor's home had been. The Telph-on-dlgreen Campus of 85 acres (340,000 m²) first became the site of Murray State Normal School, Murray Teachers College, Murray State Teachers College, Murray State College, and now Murray State University, (MSU) Did Nathan B. Stubblefield, really invent the wireless telephone? "Yes" -- said the late Murray State University Professor, Dr. Ray Mofield, Ph.D. -- "Today we call it radio!" or "Wi-Fi", says Troy Cory-Stubblefield. Short History: Nathan B.

NATHAN B. STUBBLEFIELD WAS BORN IN Murray, a small town in Kentucky, on November 22, 1860; he died on March 28, 1928, at the age of 68. From 1885 to 1913, Stubblefield invented, developed, manufactured and sold, both his wired mechanical telephone, and his wireless telephone systems through his own companies, partnerships or corporations he owned shares of stock in. The companies included: NBS Enterprises, The Wireless Telephone Company of America, The Gehring-Fennell-Stubblefield Group, The Continental Wireless Tel.&Tel Company, The Collins Wireless Telephone Company, and Telph-on-dlgreen. Since 1902, the site of the original "Telph-on-dlgreen" campus has served students from near and far, as far away as China. The campus was originally named "Telph-on-dlgreen" by Nathan B. Stubblefield, because of the nature of the land's ability to emit electromagnetic energy from the ground. This enabled him to transmit voice through the atmosphere without wires. Rainey T. Wells, was one of his first students, (1892). In 1913, options to buy the campus were sold to Rainey T. Wells and the other associates of the NBS Enterprise, known as the "big six". By 1922, the "Telph-on-dlgreen" campus became a full fledged State College and construction began. Wesley Carr was the first president and Rainey T. Wells became the second in 1927. The "Telph-on-dlgreen" campus had an enrollment of 4 students in 1902. There were 202 students when Murray State Teachers College was founded in 1922, to almost 10,000 today as MSU. Stubblefield lived in Murray, Kentucky. He was orphaned in 1874. Stubblefield was self-schooled. He married in 1881. In 1898, Stubblefield receives approval of the patent "Electric battery" (US600457; this patent for electrolytic coil is referred to as an earth battery). Edward Freeman, in his research of early experimenters stated that -- Stubblefield made his first public demonstration of any kind in Murray in 1882, when he was just twenty-two years old. On this occasion Stubblefield placed a compass in a window above the Masonic Hall on the north side of the courthouse square in Murray. He then carefully descended to the street, and while doing so kept something well hidden beneath his coat. He dug a hole, slipped whatever apparatus he was holding into it, (the ground battery) - then covered it up. Shortly after a signal from Stubblefield, there was a distinct tremor of the compass needle, a slightly jarring vibration, and the needles spun crazily. However, people were not impressed with the demonstration that it was the electromagnetic waves emitted from Stubblefield's earth battery, that got power to spin the needle. By 1885, Stubblefield Succeeded in sending voice between 2 parallel antennas by utilizing the same principals as Henry and Loomis developed in sending damped signals; except, where they used a spark transmitter, he utilized an electric current dispersion system that emitted low-frequency undamped waves, produced by his electro-magnetic induction coil. It was limited in distance, but wireless or radio nevertheless; and he offered it to his telephone customers. By 1890, Stubblefield discovered there were several methods by which articulate speech could be transmitted between two given points without connecting wires, or wireless telephony, as it is was popularly termed at the time. He sent voice frequency waves through space by modulating the electrical current through a coil of wire -- with a Berliner microphone, (the transmitter) - leading to the antenna. 1892 - First Wireless Telephone Broadcasting Demonstrations: (Voice) Nathan B. Stubblefield's first public "wireless telephone" demonstration was given in the town square of Murray, Kentucky, a radius of about one half mile. By connecting his telephone apparatus to his newly invented electrolytic coil earth battery -- that could transmit audio frequency electromagnetic waves, Stubblefield, using his grounded bare wire aerial system connected to a copper antenna placed on top of a pole -- was able to talk back and forth "without wires" to others with a like telephone, or broadcast voice and music to those listening through a mono-earphone piece. Rainey T. Wells, was one of the first persons to hear Stubblefield's wireless voice transmissions, in 1892. To Send A Voice, said Stubblefield, in 1902, AMONG THE MOST important methods are those operating: (1) by electro-magnetic induction; (2) by electric current dispersion, (wired); (3) by variation of a beam of light, (thermal); (4) by electro-static induction; and (5) by electro-magnetic waves; or (6) by a combination of all 5. The first and fifth methods, namely that of electro-magnetic induction and by electro-magnetic waves, were the simplest and easiest for Stubblefield to demonstrate to the layman on how the human voice could be transmitted and received through space, without connecting wires, "even though" he stated, "walls and other objects that obtruded the transmission, was standing in the way." For best results, to maintain articulate voice quality, he combined, early in 1890, methods 1, 2, 4 and 5 to transmit and receive articulate voice. He was the first to use a loudspeaker with his wireless. (Figure 01.2). During World I and II, the Army Signal Corps and AT&T called this combined system, the "Squier System" or "Wired Wireless". If one system was knocked out by the enemy, the other system would still operate. 1908 0512 - PATENT: Stubblefield Received His All Purpose - Wireless Telephone Patent, Number 887,357 Click to Go To US Patent Office -- then Click Full Text to refresh page. - (Patent Expires May 12, 1925) T External links and references http://smart90.com/nbstubblefield http://www.smart90.com/nbs100/ http://www.smart90.com/murraystate Information Patents Stubblefield, Nathan B.
