OK biography of inventor who promoted wireless and used it without scientifically knowing how it really worked. Best part is how it was used on the Titanic before it sank. Worth reading but there may be better biographies out there. ( ) A well-researched and well-written biography of Marconi, with a good selection of contemporary photographs which allow the reader to appreciate how different radio technology was in its early days. Marconi's life, and the world in which he lived and which affected and directed his work, is described in detail, as are the efforts of others who contributed - or claimed to contribute - to the development of radio. The part that I found frustrating was the lack of technical detail, despite the fact that it is alluded to frequently. It becomes clear that Marconi - and many others in radio's early days - simply did not understand many basic ideas of how radio worked. The problems of tuning are frequently mentioned. But I would have appreciated knowing more, from a contemporary perspective, about what they were actually doing, and why (for instance) a magnetic coherer was superior to the device which preceded it. That frustration aside, this book does an excellent job both of telling Marconi's story, warts and all, and reminding us what the world was like before radio, and the changes radio made possible. An interesting biography of Guglielmo Marconi and his role in the invention of radio. While Marconi was not the first person to transmit radio signals, and while he didn't invent the building blocks that made up radio, he was the first person able to take what was a laboratory curiosity and to turn it into a practical system for long-distance communication. It was thanks to Marconi that wireless went from sending signals a few hundred yards to spanning the Atlantic ocean in less than a decade, and so he is, more than anyone, responsible for the birth of radio. This book is an interesting account of this achievement. Zeige 3 von 3 keine Rezensionen | Rezension hinzufügen
The world at the turn of the 20th century was in the throes of "Marconi-mania" - brought on by an incredible invention that no one could quite explain, and by a dapper and eccentric figure (who would one day win the newly minted Nobel Prize) at the centre of it all. At a time when the telephone, telegraph and electricity made the whole world wonder just what science would think of next, the startling answer had come in 1896 in the form of two mysterious wooden boxes containing a device one Guglielmo Marconi had rigged up to transmit messages "through the ether". It was the birth of the radio, and no scientist in Europe or America, not even Marconi himself, could at first explain how it worked. It just did. And no one knew how far these radio waves could travel, until 1903, when a message from President Theodore Roosevelt to the king of England flashed from Cape Cod to Cornwall clear across the Atlantic. This volume is a rich portrait of the man and his era - and a captivating tale of science and scientists, business and businessmen. There are stories of British blowhards, American con artists - and Marconi himself: a character par excellence, who eventually winds up a virtual prisoner of his worldwide fame and fortune.
