Thunderstruck - Erik Larson [29]
Preece assigned engineers from his staff to assist Marconi and recruited instrument-builders in the post office mechanics’ shop to modify Marconi’s equipment to make it more robust. Immediately Preece began arranging demonstrations for other government officials.
Soon Marconi found himself on the roof of the post office, sending signals from one rooftop to another, the spark of his transmitter snapping so loudly as to be audible on the street below. In July 1896 he achieved a distance of three hundred yards, well short of what he had done at the Villa Griffone but still impressive to Preece and his engineers.
Preece arranged the most important demonstration yet, one for observers from the army and navy, to take place on the military proving ground Salisbury Plain, near Stonehenge. By day’s end he managed to transmit legible signals to a distance of one mile and three quarters.
The success of the demonstration raised Marconi onto another plane. The War Office wanted more demonstrations; Preece, nearly as delighted as Marconi, reiterated his pledge to provide as much assistance and equipment as Marconi needed. Until this point the intensity with which Marconi pursued his idea had been stoked only from within; now, suddenly, there were expectations from the outside.
“La calma della mia vita ebbe allora fine,” he said—The calm of my life ended then.
MARCONI REALIZED IT WAS NOW crucial to file for a patent for his apparatus. The number of people who had seen his invention was multiplying, and his fear that another inventor might come forward increased in step. He filed a “provisional specification” that established the date of filing and asserted that he was first to achieve the things he claimed. He would have to submit a more complete filing later.
Convinced now that Marconi truly had accomplished something remarkable, Preece decided to announce Marconi’s breakthrough to the world.
In quick succession he gave a series of important lectures, during which he introduced Marconi as the inventor of a wholly new means of communication. He gave the first in September 1896 before a meeting of the British Association for the Advancement of Science, known best simply as the British Association, during which he revealed that “an Italian had come up with a box giving a quite new system of space telegraphy.” He gave a brief description and disclosed that it had proven a great success at Salisbury Plain. In the audience were many of Britain’s most famous scientists and, of course, Oliver Lodge and some of his Maxwellian allies, including a prominent physicist named George FitzGerald. Even in the best of circumstances Lodge and FitzGerald found the experience of listening to Preece to be the intellectual equivalent of hearing a fingernail scrape across a blackboard, but now they heard him describe Marconi as if he were the first man ever to experiment with Hertzian waves, and they were outraged. Both believed Lodge had done as much in his June 1894 lecture on Hertz at the Royal Institution.
FitzGerald wrote to a friend, “On the last day but one Preece surprised us all by saying that he had taken up an Italian adventurer who had done no more than Lodge & others had done in observing Hertzian radiations at a distance. Many of us were very indignant at this overlooking of British work for an Italian manufacturer. Science ‘made in Germany’ we are accustomed to but ‘made in Italy’ by an unknown firm was too bad.” Lodge wrote to Preece and complained, “There is nothing new in what Marconi attempts to do.”
The news may have been stale to Lodge and his friends, but it was not to the world at large. Word spread rapidly about this Italian who had invented wireless telegraphy. Newspapers referred to “Marconi waves,” which to Lodge and his allies represented a cruel slight to the memory of Hertz. This Italian had invented nothing, they argued. If anyone could claim to be the inventor, it was Lodge.
