2. Famous Inventors

Consider Thomas Elva Edison — he is known as the inventor of the light bulb. However, in reality, he was not the first one to invent the electric light bulb. Edison did develop the first long-lasting, commercially successful electric light bulb.

Similarly, Guglielmo Marconi, an Italian inventor, cannot be referred to as the inventor of the radio. A few people like Oliver Lodge and Heinrich Hertz demonstrated the science behind the radio and sent the initial radio messages. Marconi simply turned radio into a more efficient technology as well as sell it to the world through daring and bold demonstrations.
