Nikola Tesla (1856-1943)
There are still people who don’t know of Tesla, but there is hardly anyone whose life is not impacted by his ingenious inventions. Let’s start with electricity, this basic facility that we won’t or can’t live without. Tesla’s alternating electric current (AC), invented at the same time as Edison’s direct current (DC), proved a safer and more cost-effective mode of power generation and distribution. Tesla is what happens every day when you turn your lights switch on!

His next grand discovery was the radio, though it was initially credited to Marconi – the patent was eventually given back to Tesla in 1943. From there Tesla invented the system of remote control. Yes, the same one you use when you flip through TV channels.

His most impressive yet controversial discovery is the Tesla Coil – the concept that the Earth itself is a magnet which generates electricity through frequencies. All that is needed for free power for everyone is a transmitter. See the controversy here?

But, back to practical, everyday solutions. Think of house appliances, machine tools, disk drives... they are all powered by the electric motor invented by Tesla. Next time when you take a cold drink from your fridge, think Tesla. Styling your hair with a hairdryer? Think Tesla. This man changed the planet as probably no one before or after him. And yes, the Tesla electric car is named after Nikola Tesla!
