RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The Internet was still largely an unknown entity at the time and not much was available in the form of WYSIWYG ...

October 1937 Radio-Craft[Table of Contents]
People old and young enjoy waxing nostalgic about and learning some of the history of early electronics. Radio-Craft was published from 1929 through 1953. All copyrights are hereby acknowledged. See all articles from Radio-Craft.
Dang, I meant to post this article on July 20th. It is an editorial commemoration written by Radio-Craft publisher Hugo Gernsback to radio pioneer Guglielmo Marconi, who died on that day in 1937. He was only 63 years old. Gernsback states, "The debt which the world owes to Marconi is staggering - if you figure only one single result of his accomplishments - the saving of tens of thousands of lives which would have perished in the sea and otherwise, if had not been for Marconi." The January 1939 issue of Radio-Craft featured an article titled, "Marconi - Father of Radio?," wherein author Edward H. Loftin challenges the veracity of Marconi receiving credit for the title. An obituary appeared in this same issue.
An Editorial by Hugo Gernsback
On July 20th, there died in Rome, Guglielmo Marconi, who may turn out to be the greatest radio figure the world has ever seen.
Marconi ... wireless ... radio; all are used synonymously and you cannot very well think of wireless or radio without the accomplishments of that indefatigable genius who was the first to capture the public's imagination by an accomplishment,. which in the early years of wireless well nigh bordered on the miraculous.
Marconi no doubt will go down in history as one of the race's great benefactors, as great or greater than any other benefactor who ever lived. The debt which the world owes to Marconi is staggering - if you figure only one single result of his accomplishments - the saving of tens of thousands of lives which would have perished in the sea and otherwise, if had not been for Marconi.
But the saving of untold lives is only one of the things that the world is indebted for to Marconi. The wireless, later the radio age, has brought to life not only a huge industry, but has brought all humans closer together, has made rapid communication, particularly between fixed and mobile stations, a possibility and lately in broadcasting has given the human voice wings such as it never before dreamt of having.
Yet great as Marconi's accomplishments are, he was not the pure inventor type of man, although his name is frequently linked with the word "inventor." Without trying to detract from Marconi's greatness - there could be nothing further from my mind - Marconi was really not the man who invented wireless or radio. He admitted this freely in his own lectures. The credit for the original invention belongs to Heinrich Hertz, who, long before Marconi, investigated in pure scientific terms the electromagnetic waves, and indeed to Hertz belongs the honor of being the real Father of Radio.
Hertz it was who in his laboratory actually transmitted and received wireless signals. By means of a spark coil he let loose into free space wireless waves. For a receiver, he merely used a small loop of copper wire and observed a small spark which appeared between the two open ends of the loop every time the key of the transmitter was depressed. These experiments were made by Hertz while Marconi still was a boy, but, Hertz was a pure physicist and had little imagination. Marconi, reading of Hertz's experiments, promptly started to experiment on his own behalf, and soon he had a wireless transmitter and receiver going on his father's estate in Bologna, Italy. Even Marconi's "coherer" was not his own invention, but Branley's. Others before had noted that loose metallic filings in a glass tube became conductive to the electric current when exposed near the wave effect of a spark coil or high-power induction coil.
As for the elevated aerial used by Marconi, this also was not an invention of his own as Nikola Tesla had already patented a wireless system years before the youthful Marconi began his own experiments. It was Tesla too, who seems to be the first to show the use of an elevated conductor for inter-communication purposes without wires.
All of this should not detract anymore from the glory of Marconi's accomplishments than the parallel facts that Edison was not the original inventor of either the electric light, motion picture or other inventions usually accredited to him; Neither Marconi nor Edison were pure research men who discovered new principles and used them.
Why then Marconi's greatness? It is one thing to discover an important and record-making discovery, but it is quite another thing to find a practical use for it. The two, as a, rule, have little relation, and it is usually the man with the imagination, and the hard-working experimenter who, knowing certain principles, applies them to practical use. If it had not been for Marconi, Hertz's discovery might have lain dormant for decades, but the highly original experiments and the terrifically hard work coupled with boundless enthusiasm which Marconi applied to a well-known principle, gave him the credit which rightfully belongs to him.
And let no one think that it was all easy and that wireless communication sprang into life overnight. It was always hard work in the face of an incredulous world. Indeed, after his first experiments in Italy were successful, the Italian government in their shortsightedness would have nothing to do with Marconi's "contraption" as they termed it. This made it necessary for Marconi to go to England and continue his experiments there. Soon his signals had reached across the English channel to France, and from then on wireless communication required no further proofs of its practicability.
But still wireless in those days was very crude and far from universal. In the meanwhile Marconi surrounded himself with good technical talent; he also knew where to get needed finances, and finally he availed himself of every new invention that came along to make his system more practical. While he devised many radio circuits, ,he did not himself discover the fundamental tuning principle, yet he improved existing methods of tuning - syntony - as it was then called; and soon it became possible to operate many wireless stations without too much interference from each other.
But Marconi was not content. He never rested on his laurels. He always was a modest worker who gave credit to whom credit was due, and the honors for dreaming about trans-Atlantic wireless and the courage to actually start experimenting with it in the face of an incredulous world, certainly belong to Marconi. It should not be forgotten that it took a tremendous amount of courage and belief in himself to think that a new and untried system of transmitting electromagnetic waves over almost 2,000 miles of curved ocean surface was within the realm of even a remote possibility. That took more than courage. It was really a supreme heroic gesture, and it is probably for this one outstanding accomplishment, more than any other, that the world is paying homage to the dead inventor today.
In his later years, Marconi again was responsible for great improvements in radio communication, particularly in the shortwave range and his final researches in the microwave field which hold great promise, were cut short by his untimely death.
Marconi was truly an international figure, and if there is one man who ever trod the earth, who is entitled to have a monument erected in his honor in every civilized country on the globe, that man without a shadow of a doubt is the illustrious Marconi.
