New York State and many other states in the USA proclaimed July 10, Tesla's birthday- Nikola Tesla Day. The street sign "Nikola Tesla Corner" was recently placed on the corner of the 40th Street and 6th Avenue in Manhattan. There is a large photo of Tesla in the Statue of Liberty Museum. The Nobel Prize in Physics was awarded to Marconi for radio in 1909.

In December 1901, Marconi established wireless communication between Britain and the Newfoundland, Canada, earning him the Nobel prize in 1909. But much of Marconi's work was not original. In 1864, James Maxwell theorized electromagnetic waves. In 1887, Heinrich Hertz proved Maxwell's theories. Later, Sir Oliver Logde extended the Hertz prototype system. The Brandley coherer increased the distance messages could be transmitted. The coherer was perfected by Marconi.

However, the heart of radio transmission is based upon four tuned circuits for transmitting and receiving. It is Tesla's original concept demonstrated in his famous lecture at the Franklin Institute in Philadelphia in 1893. The four circuits, used in two pairs, are still a fundamental part of all radio and television equipment.

The United States Supreme Court, in 1943 held Marconi's most important patent invalid, recognizing Tesla's more significant contribution as the inventor of radio technology. That Nobel prize given to Marconi, was really Nikola Tesla's Nobel prize.
