Sometimes scientific breakthroughs occur when people challenge popular belief. When scientists thought that radio waves could not travel long distances because of the Earth’s curvature, Guglielmo Marconi proved them wrong. He conducted the first successful wireless communication from England to North America. He accomplished the feat without a formal university education, and admitted when he accepted the Nobel Prize in physics that he did not fully understand how his own invention worked.

Marconi was born April 25, 1874, in Bologna, Italy. His father, Giuseppe Marconi, was Italian, and his mother, Annie Jameson, was an heir to the Jameson whiskey family in Ireland. He spent about half of his childhood in Italy, and the other half in England, where he learned the language.
