Did you know that Guglielmo Marconi was born today in 1874? He was an Italian electrical engineer and inventor. He is best known for his work with ‘wireless telegraphy’, or sending and receiving messages using radio waves instead of metal wires. His early experiments were only able to transmit signals across a room. After many years of experimenting, study, and redesign, Marconi’s high-powered radio stations were able to send and receive signals across the Atlantic Ocean (more than 2000 miles)!
We hope that you have an innovative day at school. Remember to think kind thoughts, use kind words, and do kind things. We Love You.
Marconi was only 20 when he started his first experiments with wireless telegraphy. He was assisted by his butler, Mignani.
When he was 21, Marconi moved from Italy to London, where he received better support for his research.
Marconi’s Law, which was developed by Guglielmo Marconi. It shows the relationship between the height of antennas and the distance which they can send and receive transmissions.
Along with Karl Ferdinand Braun he was awarded the 1909 Nobel Prize in Physics for his work in wireless telegraphy.
In 1915, the Titanic carried one of Marconi’s radio transmitters. It allowed the Titanic to signal for help after it struck the iceberg. It was said, “Those who have been saved, have been saved through one man, Mr. Marconi…and his marvelous invention”
