Thomas Alva Edison was the most prolific inventor in American history. He amassed a record 1,093 patents covering key innovations and minor improvements in wide range of fields, including telecommunications, electric power, sound recording, motion pictures, primary and storage batteries, and mining and cement technology

He applied for his first patent in 1868, when he was just 21 years old. The famous inventor’s first brainchild was for a device that recorded legislative votes. That was just the start of a career in which he would obtain 1,093 U.S. patents, in addition to another 500 to 600 applications that he either didn’t finish or were rejected. But Edison’s greatest invention may have been developing a new process for coming up with inventions.

“When Edison raised enormous capital, built a laboratory in Menlo Park, N.J., and hired a staff of several dozen, each with distinct talents, he pioneered what became the modern corporate research and development process,” explains Ernest Freeberg, a historian at the University of Tennessee, Knoxville and author of The Age of Edison: Electric Light and the Invention of Modern America.

In many cases, Edison’s genius was taking a new technology that someone else had pioneered and developing a superior way of doing the same thing. “An invention not only has to work fairly well, but it has to be something that the market wants and can afford to buy. Edison understood that as well as anyone in his day,” says Freeberg.

By the time of his death on October 18, 1931, Edison had received 1,093 U.S. patents, a total still untouched by any other inventor. Even more important, he created a model for modern industrial research.

Tesla was a scientist and visionary who developed the basis for AC electric power that most of the planet uses today and pioneered numerous technologies that improve our everyday lives. A Serbian-American who emigrated to New York City in 1884, Tesla held approximately 300 patents.Tesla was involved in many more discoveries and creations, including the rotating magnetic field, the speedometer, and the Tesla Coil, which is a transformer that produces sparks by creating high voltage at a low current

Tesla's often compared with Thomas Edison, but he was in many ways Edison's opposite. Edison claimed invention was "1 percent inspiration, 99 percent perspiration". Yet Tesla was very much a man of inspiration, a visionary. Edison was self-taught; Tesla had received a thorough technical education. Edison solved practical problems; Tesla dreamed of world-transforming technology. Edison commercialized his inventions; Tesla had little business sense. About the only thing they had in common was that both men got by on little sleep: Tesla sometimes worked from 10:30 a.m. to 5 a.m. the next morning.

Tesla invented one of the world's earliest remote controls, which he called a "teleautomaton." He patented his device in 1898 as a "Method of and Apparatus for Controlling the Mechanism of Moving Vessels or Vehicles," which he used it to control a miniature boat from afar during a demonstration at Madison Square Garden.

Tesla was also a pioneer of X-ray technology. He experimented with radiation and managed to take some of the first X-ray images of the human body, which he called "shadowgraphs." Tesla was also one of the first scientists to hypothesize that X-rays could be harmful.

Tesla was also a pioneer of renewable energy. Nine out of the 12 patents used to build one of the world's first hydroelectric stations, erected at Niagara Falls, New York belonged to Tesla.
