Nikola Tesla, father of modern methods of generation and distribution of electrical energy, who was 78 years old yesterday, announced a new invention, or inventions, which he said, he considered the most important of the 700 made by him so far.
By 1937 it was clear that war would soon break out in Europe. Frustrated in his attempts to generate interest and financing for his "peace beam," he sent an elaborate technical paper, including diagrams, to a number of Allied nations including the United States, Canada, England, France, the Soviet Union, and Yugoslavia. Titled "New Art of Projecting Concentrated Non-Dispersive Energy Through Natural Media," the paper provided the first technical description of what is today called a charged particle beam weapon. Of all the countries to receive Tesla's proposal, the greatest interest came from the Soviet Union. In 1937, Tesla presented a plan to the Amtorg Trading Corporation. Two years later, in 1939, one stage of the plan was tested in the USSR, and Tesla received a check for $25,000.
