Did Nikola Tesla help any other scientists?
Tesla is now credited with inventing modern radio as well; since the Supreme Court overturned Guglielmo Marconi's patent in 1943 in favor of Nikola Tesla's earlier patents. When an engineer once said to Tesla, "Looks as if Marconi got the jump on you" regarding Marconi's radio system, Tesla replied, "Marconi is a good fellow. Let him continue. He is using seventeen of my patents." Edison hired Tesla to work for his Edison Machine Works. Tesla's work for Edison began with simple electrical engineering and quickly progressed to solving some of the company's most difficult problems. Tesla was even offered the task of completely redesigning the Edison company's direct current generators. Tesla claims he was offered US$50,00 if he redesigned Edison's inefficient motor and generators, making an improvement in both service and economy. In 1885 when Tesla inquired about the payment for his work, Edison replied, "Tesla, you don't understand our American humor," thus breaking his word. Earning US$18 per week, Tesla would have had to work for 53 years to earn the amount he was promised. The offer was equal to the initial capital of the company. Tesla immediately resigned when he was refused a raise to US$25 per week.
