Guglielmo Marconi invented the radio because he was fascinated by electrical science and physics and wanted to expand upon the work of Heinrich Rudolf Hertz in the field of electromagnetic radiation. Due to his family's wealth, he was able to conduct experiments on his own at the family villa, which led to the development of the radio.
Marconi's interest was sparked by articles that appeared after Hertz's death. He was able to study under Augusto Righi, a university physicist and neighbor of Marconi who had researched Hertz's work. Working alone in an attic with only his butler to assist him, Marconi created a device that could send signals over a mile away.
The Italian government rejected his request for funding, so in 1896 Marconi, accompanied by his mother, went to England. The British Post Office was among the groups interesting in financing his work. In 1899, Marconi sent the first wireless radio signals across the English Channel from France to England. In 1902, he successfully sent a signal across the Atlantic Ocean from Canada to England. Early versions of Marconi radios were crucial in saving hundreds of lives when the Titanic sank in 1912.
In addition to his first patent for tuned telegraphy in 1900, Marconi received several other patents for his inventions. These included a magnetic detector that became the first wireless receiver, a horizontal directional aerial and a system for generating continuous waves. In 1909, Marconi received the Nobel Prize in physics for his work.
