On May 14-16, 2010, over 15,000 ham radio enthusiasts gathered for the annual Hamvention in Dayton, Ohio.

Even today, Marconi is commonly remembered as “the inventor of radio,” although the priority of other inventors–notably Nikola Tesla–is fairly well established. The debate over who is rightfully credited for the invention of radio has become known as “The Great Radio Controversy” (Wikipedia). Even so, there is no debate that Marconi’s achievements as an engineer, inventor, and businessman are of historic significance. He shared the 1909 Nobel Prize in Physics with Karl Ferdinand Braun, “in recognition of their contributions to the development of wireless telegraphy.” Marconi died in 1937, aged 63.
