Spark-gap transmitter capacitance and couldn't store much charge, limiting their power output. Therefore these devices were not capable of long distance transmission; their reception range with the primitive receivers employed was typically limited to roughly 100 yards (100 meters). Italian radio pioneer Guglielmo Marconi was one of the first people to believe that radio waves could be used for long distance communication, and singlehandedly developed the first practical radiotelegraphy transmitters and receivers, mainly by combining and tinkering with the inventions of others. Starting at age 21 on his family's estate in Italy, between 1894 and 1901 he conducted a long series of
Alexander Bain (inventor) restored in 1959. The headstone had a fallacious date of death (1876) which was later corrected to 1877. JD Wetherspoons pub in Wick, close to where Alexander Bain served his apprenticeship, is now named 'The Alexander Bain' after the inventor. Also, as a tribute to his inventions, the main BT building in Glasgow is named Alexander Bain House. One of the earliest examples of an electrically impulsed pendulum clock is on display at the Deutsches Uhrenmuseum. In 2016 he was awarded the Technology & Engineering Emmy Award "for his pioneering work in the transmission of images". Alexander Bain (inventor) Alexander
