Inventor, engineer and futurist, Nikola Tesla, is best remembered for his contribution to the development of the modern alternating current (AC) electricity supply system. A prolific inventor, he had around 300 patents for his inventions. Even though he earned a considerable amount of money, he had poor money management skills and died a poor man.
Described as America’s greatest inventor, Thomas Edison’s legacy is an everlasting one. He was the first to help make the incandescent light bulb commercially viable, even though he was not the first inventor of it. Quadruplex telegraph, phonograph, motion picture camera and the alkaline storage battery are some the many innovations that made him a worldwide phenomenon and an icon.
Orville Wright was an aviation pioneer who alongside his brother, Wilbur, built and flew the world's first successful motor-operated airplane, the Wright Flyer, a heavier-than-air aircraft. The three-axis control system developed by the brothers remains standard on fixed-wing aircraft of all kinds. Orville also served on the board of the National Advisory Committee for Aeronautics (NACA).
Alexander Graham Bell was a scientist, inventor, and engineer. He is credited with inventing the first functional telephone. He is also credited with co-founding America's major telephone company AT&T, which has been going strong since 1885. Bell's later life was marked by his groundbreaking work in aeronautics, hydrofoils, and optical telecommunications. He was also an ardent supporter of compulsory sterilization.
The son of a machine shop owner, Robert H. Goddard grew up to become a pioneer of rocketry. Interested in physics and mechanics since childhood, he dreamed of space flight. He developed the world’s first rocket that ran on liquid fuel. NASA's Goddard Space Flight Center is named after him.
German-born American aerospace engineer and space architect, Wernher Von Braun, worked in Nazi Germany's rocket development program as a young man. After World War II, he moved to the United States where he became a pioneer of rocket and space technology in the nation. In his later career, he became director of the newly formed Marshall Space Flight Center.
Before she turned her peculiar inventions into a billion-dollar business empire, Joy Mangano had worked as an airline assistant and a waitress. Her best-known invention has been the Miracle Mop, a self-wringing mop made of plastic. She has also penned a memoir and has inspired the 2015 film Joy.
Garrett Morgan is remembered for inventing the Morgan safety hood, which served as a prototype for later gas masks. He also invented the T-shaped traffic signal and a range of hair-care products, such as hair straightening creams. An NAACP member, he also launched a newspaper to cater to African-Americans.
American engineer Robert Noyce, who co-invented the integrated circuit, later gained the nickname the Mayor of Silicon Valley. The co-founder of Intel and Fairchild Semiconductor, Noyce is also said to have given Silicon Valley its name with his invention that included a silicon microchip. He was also a swimming champion.
Inventor and entrepreneur George Westinghouse was mostly responsible for introducing the U.S. to alternating current (AC). Initially part of the army and the navy, the talented engineer began his journey of inventions with the rotary steam engine and went on to invent several products, such as air brakes.
George Eastman revolutionized the world of photography with his Eastman Kodak Company and the roll film, which also came to be used in movies. Initially a banker, he later devoted himself to his camera company. A dedicated philanthropist, too, he contributed financially to music, dentistry, and medicine.
