Man of High Fidelity
Man of High Fidelity: EDWIN HOWARD ARMSTRONG A Biography – By Lawrence Lessing With a new forward by the author Page iii Pratt DISCLAIMER DISCLAIMER TO THIS SCANNED AND OCR PROCESSED COPY This PDF COPY is for use at Pratt Institute for Educational Purposes Only I affirm that sufficient print copies of the original Bantam Book Paperback are in stock in ARC E-08 that would more than adequately cover a full class use of the text. HOWEVER, due to the fact that the 1969 text is no longer in publication, complicated by the fact that these copies are forty-four (44) years old and in a very fragile condition, this PDF version of the text was created for student use in the Department of Mathematics and Science. - Professor Charles Rubenstein, January 2013 Man of High Fidelity: Edwin Howard Armstrong EDWIN HOWARD ARMSTRONG Was the last – and perhaps the least known – of the great American Inventors. Without his major contributions, the broadcasting industry would not be what it is today, and there would be no FM radio. But in time of mushrooming industry and mammoth corporations, the recognition of individual genius is often refused, and always minimized. This is the extraordinary true story of the discovery of high fidelity, the brilliant man and his devoted wife who battled against tremendous odds to have it adopted, and their long fight against the corporations that challenged their right to the credit and rewards. Mrs. Armstrong finally ensured that right nearly ten years after her husband’s death.

Tesla's Connection to Columbia University by Dr. Kenneth L. Corum
* Tesla’s Connection to Columbia University by Kenneth L. Corum and James F. Corum, Ph.D. “The invention of the wheel was perhaps rather obvious; but the invention of an invisible wheel, made of nothing but a magnetic field, was far from obvious, and that is what we owe to Nikola Tesla.” Professor Reginald Kapp, 1956 INTRODUCTION The Electrical Engineering curriculum at Columbia University, though not the first in the US, is one of the oldest and most respected EE programs in the world. From the beginning, a conscientious effort was made to base it on a foundation of science. It has been guided by the specific philosophy stated by Professor Michael Pupin: “Professor Crocker and I maintained that there is an ‘electrical science’ which is the real soul of electrical engineering.” Arguably the most stunning and significant lecture in modern history was presented one spring evening, more than a century ago, at Columbia University. The wealth of nations turned on its merits. Weighing on the balances would be our vast cities, civilization, and quality of life. But, what was it? . .Whatever it was, its impact has been as momentous for the progress and prosperity of civilization as the invention of the wheel! . It was Tesla’s great discovery and analysis of the rotating magnetic field, and a means for the electrical distribution of energy.1 As a result of the analysis presented in this lecture, the great Falls of Niagara would soon be harnessed for the benefit of mankind and launch civilization into the “Electromagnetic Century”. The Engineering Council for Professional Development (now called ABET) has defined “Engineering” as “that profession which utilizes the resources of the planet for the benefit of mankind”. -

The Struggle for the Range of Telephone Communication Before the Invention of the Audion Lee De Forest
ITM Web of Conferences 30, 16002 (2019) https://doi.org/10.1051/itmconf /201930160 02 CriMiCo'2019 The struggle for the range of telephone communication before the invention of the audion Lee de Forest Victor M. Pestrikov1, and Pavel P. Yermolov2 1Saint-Petersburg State University of Film and Television 13, Pravda Str., Saint-Petersburg, 191119, Russian Federation 2Sevastopol State University, 33, Universitetskaya Str., Sevastopol, 299053, Russian Federation Abstract. The increase in the range of laying telephone lines at the beginning of the 20th century raised the issue of high-quality telephone signal transmission for scientists and engineers. The innovative technology for solving the problem was based on the “Heaviside condition”. AT&T engineer George Campbell, who received a patent for the design of load coils, was engaged in this task. He demonstrated that a telephone line loaded with coils can transmit clear voice signals twice as far as unloaded telephone lines. At about the same time, Columbia University professor Michael Pupin dealt with this problem, who also received a patent for a similar concept in priority over Campbell's application. As a result, load coils became known as “Pupin coils”. Ironically, Campbell lost the patent priority battle. The proposed innovation eliminated time delays and distortions in the signal, thereby significantly increasing the transmission speed. 1 Introduction The operation of long-distance telephone lines, at the beginning of the 20th century, revealed a number of their shortcomings, among which the main thing was noted - the low quality of human speech transmission [1]. The arising problem required its quick solution. New cable designs were needed that were fundamentally different from the existing ones, especially telegraph cables. -

Guglielmo Marconi Wikipedia, the Free Encyclopedia Guglielmo Marconi from Wikipedia, the Free Encyclopedia
10/5/2016 Guglielmo Marconi Wikipedia, the free encyclopedia Guglielmo Marconi From Wikipedia, the free encyclopedia Guglielmo Marconi, 1st Marquis of Marconi (Italian: [ɡuʎ ˈʎɛlmo marˈkoːni]; 25 April 1874 – 20 July 1937) was an Italian Guglielmo Marconi inventor and electrical engineer known for his pioneering work on longdistance radio transmission[1] and for his development of Marconi's law and a radio telegraph system. He is often credited as the inventor of radio,[2] and he shared the 1909 Nobel Prize in Physics with Karl Ferdinand Braun "in recognition of their contributions to the development of wireless telegraphy".[3][4][5] Marconi was an entrepreneur, businessman, and founder of The Wireless Telegraph & Signal Company in the United Kingdom in 1897 (which became the Marconi Company). He succeeded in making a commercial success of radio by innovating and building on the work of previous experimenters and physicists.[6][7] In 1929, the King of Italy ennobled Marconi as a Marchese (marquis).
