(2) Thomas Edison vs. (7) Nikola Tesla

(2) Thomas Edison

The sheer scope of Edison's inventiveness is staggering. The Wizard of Menlo Park held a record 1,093 patents when he died in 1931. Everyone knows him for the light bulb, but Edison also had a hand in the invention of the radio, the phonograph, and an improved stock ticker. His achievements weren't all nerdy science, either; Edison's electric engraving pen needed just a few modifications to become the world's first tattooing machine.

(7) Nikola Tesla

Not since Benjamin Franklin has one man's name been so inextricably linked to electricity. Tesla's major breakthroughs, including the rotating magnetic field, made the alternating current we use in our homes possible. His Tesla coil was a key part of early radios. He's still revered as a god among electrical engineering fans, and he might just have been the most important inventor of the 20th century.

The Breakdown

A bitter grudge match over a century in the making! These two had legitimate beefs on both a scientific and a personal level. When Tesla arrived in the U.S. in 1884 with little more than four cents and a schematic for a flying machine, Edison was his first employer. Edison allegedly jilted Tesla on payment, and the two had a falling out. Later, they engaged in a "War of Currents" over whose system of electric power distribution was superior, with Edison backing direct current and Tesla in alternating current's corner. In the end, Tesla got the last laugh. Alternating current brings juice into our homes, and he outlived Edison, which enabled him to slam Edison in the New York Times on the day after his rival's death. Which one's the bigger genius, though?

Tournament of Genius: The Winner Is...

Leo wins! According to mental_floss's learned readers, Leonardo da Vinci is history's greatest genius. While the Renaissance man may have easily bested Albert Einstein in the 65-person tournament's final round, his path to the title wasn't so easy. He had to survive a controversial first-round matchup against Burt Reynolds that went into a runoff due to allegations of voter fraud, and then he had to slip past Sigmund Freud, Galileo, Nikola Tesla, and Benjamin Franklin.

Through it all, though, the Italian polymath's supporters came out in droves, and it seems that no other genius could quite match Leonardo's combination of artistic mastery and scientific acumen. Congratulations, Leonardo! Consider this one more addition to your lengthy, impressive resume.

The Title Game: Einstein vs. Leonardo

The Breakdown

This matchup has seemed inevitable since we released the brackets, hasn't it? We've already filled you in on what each of these geniuses accomplished, but it's worth running through the list one more time before you decide who should take the title.

Einstein's output in 1905 alone was enough for an entire lifetime of work. In that "miracle year" he published four papers that altered humanity's understanding of physics. One explained the photoelectric effect, while another offered an explanation for Brownian motion and the first experimental proof of the existence of atoms. The third and fourth papers laid out his theories of special relativity and his famous "E equals MC squared" formula. Any one of these papers would have been an incredible Nobel-worthy triumph, and he banged out all four in a single year. When early Nazi propaganda targeted Einstein and the "Jewish physics" of relativity and forced other scientists to renounce relativity, he fled to the United States, where he eventually helped convince Franklin Roosevelt to develop the atomic bombs that would end World War II. Later in his life Israeli officials offered Einstein the presidency of their country, although he declined.

Leonardo, for his part, was just as busy. The Renaissance man felt that it was his duty to take in as much knowledge as he possibly could, so he threw himself into all sorts of studies. Works like his Last Supper and Mona Lisa show his artistic virtuosity, particularly his mastery of smoky shadows, but it's his scientific and engineering work that really sets Leonardo apart from the crowd. When he died, Leonardo left hundreds of pages of journals detailing his observations on all sorts of natural sciences, including botany, anatomy, and zoology. His architectural studies were far-reaching and diverse, and his engineering sketches proved to be well ahead of their time, particularly his designs for flying machines, tanks, parachutes, and an early forerunner to the machine gun. Leonardo may not really have only slept for 15 minutes at a time, but with accomplishments like this, it's easy to see how that urban legend could spread.

Which one are you going to pick as your top genius, though? Einstein, the scientific powerhouse who won the Nobel and has given us fodder for countless magazine covers? Or do you like Leonardo, the brilliant artist who managed to learn a little bit about almost everything else, too? They're both great, but there can be only one champion.
