1. Thomas Edison (1847-1931)

The Edison Lightbulb: A Revolution in Lighting - CantoUSA

Thomas Edison was an incredibly prolific American inventor whose inventions changed how we live every day. He invented the practical electric light bulb to light homes and cities, constructed the phonograph for recording sound, and created early motion picture cameras that forever changed motion picture viewing.

Edison held more than 1,000 patents and pioneered the idea of industrial research laboratories. His inventions laid the groundwork for modern technologies and created industry and making him one of the most prominent figures in the history of science.

2. Benjamin Franklin (1706-1790)

TIME for Kids | Benjamin Franklin

Benjamin Franklin was a polyhistor whose contributions to science and to society have durable significance. He studied electricity through various investigations, including one in which he flew a kite to investigate lightning. He invented the lightning rod, bifocals, and the Franklin stove. 

He exhibited the same perseverance as a diplomat, author, and one of the founding fathers of the United States. Franklin's inquisitiveness, creativity, and hands-on inventions improved living and inspired subsequent generations of American inventors.

3. Albert A. Michelson (1852-1931)

WORLDKINGS - Worldkings News - America – Albert Abraham Michelson: First  American to win Nobel prize in Physics - Worldkings - World Records Union

Albert A. Michelson was the first American to win a Nobel Prize in Physics. He is best known for the Michelson-Morley experiment, which investigated the speed of light, tested the idea of "ether," and laid the groundwork for Einstein's theories of relativity. 

Michelson's precision instruments and focus on experimental physics idealistically advanced our understanding of the physics of science and established the United States's position as a preeminent participant in the development of modern physics. Michelson's work is foundational to our understanding of optical science.

4. Richard Feynman (1918-1988)

Richard Feynman: The Man Who Only Used His Intellect to Enjoy Life | by Ali  | Medium

Richard Feynman was a gifted physicist, made famous for his contributions to quantum electrodynamics and particle physics. Feynman made meaningful contributions in theory and was awarded the Nobel Prize in Physics in 1965. Feynman did not stop at the research lab, however.

Feynman was a brilliant educator who moved comfortably between the research lab and the classroom. He was famous for making complicated physics concepts easy to grasp and motivating young scientists with vivid lectures or writing. Feynman used curiosity, creativity, and a bit of childlike wonder to be one of the most highly regarded, honored, and loved American scientists of the 20th Century.

5. Jonas Salk (1914-1995)

8 Things You May Not Know About Jonas Salk and the Polio Vaccine | HISTORY

Jonas Salk was a groundbreaking medical researcher who created the first safe and effective polio vaccine. His invention greatly reduced the incidence of polio around the world, saved millions of lives, and improved public health. 

Salk chose not to file for a patent on his vaccine so it could be made available to the global population rather than simply profiting from it for himself. His commitment, humanitarian approach, and scientific talent elevated him to a heroic status in medicine and one of the most honored scientists in American history.
