JChris (J. Chris Coppick) writes "Wireless technologies threatening cable monopolies; an underground network of amateurs fighting regulation; legal battles over patent rights; phone owners complaining about telemarketers; car enthusiasts complaining about speed traps ... This may sound like a summary of today's headlines, but these and other familiar conflicts were hot even at the beginning of the 1900s. In Signor Marconi's Magic Box, Gavin Weightman tells the story of the life of Guglielmo Marconi, and of the communications revolution sparked by Marconi and others around the turn of the 20th century."

This biography of Marconi, published by Da Capo Press in 2003, is just one in a group of science-related historical accounts that I've been working my way through of late, but stands out from the others in sheer deja vu. Before getting into that, though, let us focus first on the author's deftly accomplished goal of fitting the story of Marconi's life and the development of wireless telegraphy (along with a more than adequate treatment of the historical context) into a book of approximately 300 pages (including two small sections of well-annotated photographs).

For those not familiar with Marconi beyond his popular title as the inventor of the radio, one of the first surprises is that much of the story takes place in England and not Italy, due in no small part to the fact that Marconi's mother was Irish. Marconi was born in Bologna, Italy in 1874. He was raised there, and it was in Bologna that he laid the foundation for his future successes in the wireless business. While the existence of "Hertzian" waves was known before Marconi's work, and even though their use as a medium of communication was certainly being considered by others at the time, Marconi can be credited with key innovations that led to the first practical system of wireless telegraphy. In 1896 he traveled to England to popularize his wireless system, with the help of his mother's family connections. Thus it was England where Marconi launched his first wireless enterprise, and England remained his base of operations for the bulk of his career.

For those not familiar with the history of radio, another surprise may be how just many obstacles initially stood in the way of wireless communication. The BBC World News broadcast didn't start the day after Marconi said, "Aha!" Many of the problems stemmed from a general ignorance of the actual physics involved in radio transmission. For example, early wireless sets worked better during the night than the day (like your radio's AM tuner), and early long-distance transmitters required large amounts of power. The advantages of "short waves," much less the theoretical underpinnings, were not recognized until rather late in the story, relative to Marconi. Marconi himself had little understanding of why his "magic boxes" worked. He focused rather on mechanical innovations that increased the convenience and reliability, and therefore the commercial possibilities, of his previous successes. In this respect, Marconi was much more of a craftsman and businessman than a scientist.

By 1900 there were two companies bearing Marconi's name (the Marconi Wireless Telegraph and Signal Company, and the Marconi International Marine Company), though like the true startups they were, neither were making any money. Soon Marconi was almost completely focused on making trans-Atlantic wireless telegraphy a reality. It was near this point in the narrative that I started to see reflections of "modern" legal, political, and cultural themes.

For the curious, let's dispense with these first: Marconi was an "early adopter" of the then-recent advances in automobile technology (he was seriously injured in an automobile accident later in his life). So the book makes mention of the fact that, because of the rapid rise in the popularity of motoring, as early as 1904 the police in England were setting up "speed traps." So the next time you are yelling at the cop who just pulled you over, take a moment to consider your small but vital role in over 100 years of tradition. Also of interest, the book discusses the roots of the "broadcast" concept, some of which involved the telephone system. This leads to the mention of consumer complaints, dating back to the early 1900s, about unsolicited sales calls. I won't ask you to consider, the next time your dinner is interrupted, your small but vital role in that tradition. It's just too depressing.

In December of 1901, Marconi received in Newfoundland the first trans-Atlantic wireless telegraph signal, transmitted from one of his stations in England. At that time, the business of trans-Atlantic communications (i.e. telegraph messages) was monopolized by the small set of companies that owned undersea cables. One cable company even had a legally-defined monopoly on telegraphy in Newfoundland, a fact they quickly pointed out to Marconi, forcing him to take his business to Canada. [ed. note: Newfoundland didn't join Canada until 1949.]

As news of Marconi's accomplishment spread, cable-company stocks began to "wobble." It was assumed by many that once long-distance wireless telegraphy became widespread, the lower cost-per-message for wireless would put the cable companies out of business. Of course, that never really happened. (It's worth noting here that the revolution of radio broadcast came later. Just as no one looking at the ARPANET could see Slashdot, no one looking at the first wireless efforts could see Wolfman Jack, Howard Stern, or Rush Limbaugh.) Soon however, despite the lack of much actual commercial wireless success, "wireless mania" was spreading through parts of the world, especially in the United States. Fraudulent businesses were created, patents (legitimate and otherwise) were being granted, competing standards were leading to international political frictions, patent-infringement suits were being brought, competitors were being bought out, and amateurs were gleefully "hacking" the system. It wasn't long before government regulations were being imposed and bureaucracy was slowing down the adoption of new technologies. Hopefully you can see why all this started to feel more than just vaguely familiar. I do not want to leave anyone with the impression that Signor Marconi's Magic Box is just a depressing litany of the recurring problems of civilization. It's hardly that. Actually the fact that I was able to identify on a modern level with much of the history made an already interesting book even more interesting.

Signor Marconi's Magic Box is pretty much everything you could want in a historical biography, perhaps more. The author touches on enough aspects of the development of wireless telegraphy to keep the story fresh, including most if not all of the personalities involved, and he seems to give credit where it's due. He provides enough detail of Marconi's life to give us a good sense of the man, but not so much as to weigh down the narrative. Likewise, he provides enough technical detail to give us a sense of the technology, but not so much as to detract from the human aspects of the tale. If you are not hooked yet, please allow me brief mention of some other aspects of the story, including: forbidden love, intrigue, war, murder, shipwrecks, practical jokes, heroic deeds, another war, and international espionage. If I had to sum it all up in one sentence it would be this: Any book that contains the phrase "two-ton transformer blew up" can't be all bad.
