Did You Know?
The invention of the wireless telegraph was originally attributed to Guglielmo Marconi. Marconi used inventor Nikola Tesla's patents and put them together in a way that looked unique enough to earn a patent. It would take nearly 30 years for Tesla to get credit for his invention. Though, Tesla was not too worried about Marconi, Thomas Edison was the real worry for Tesla. Edison often would steal inventions from other people, claim them as his own, and if the true inventor complained, Edison would send some "hired help" to change their minds.
Too show just how powerful Edison was during his life, simply look at a history book. Edison made sure he would be taught to students as the "father of invention."
