Richard Phillips Feynman
Was an American theoretical physicist, known for his work in the path integral formulation of quantum mechanics.

Feynman developed a widely used pictorial representation scheme for the mathematical expressions describing the behavior of subatomic particles, which later became known as Feynman diagrams.
Here's a time line of Mr Feynman's life:
- May 11, 1918- Richard Feynman is born in Manhattan, New York to Melville Feynman and Lucille Phillips.
- January 1, 1939- Richard Feynman earns a B.Sc from Massachusetts Institute of Technology(MIT). MIT is where he found his interest in Theoretical Physics.
- 1941-1942- Richard Feynman works on the atomic bomb project at Princeton with Albert Einstein.
- January 1, 1942- Richard Feynman gets married for the first time with his high school sweetheart Arline.
- 1942- Richard Feynman graduates from Princeton and earns a PhD.
- 1945- Richard Feynman is taught physics at Cornell.
- January 16, 1945- Richard Feynman's wife Arline dies.
- June 1, 1952-Richard Feynman remarries the first time with Marry Louise Bell.
- 1956- Richard Feynman and Marry Louise Bell divorce.
- January 1960- Richard Feynman remarries again with Gweneth Haworth.
- 1961- Richard Feynman releases his first of 10 books.
- December 10, 1965- Richard Feynman wins the Nobel Prize in physics for "their fundamental work in quantum electrodynamics, with deep-ploughing consequences for the physics of elementary particles."
- February 15, 1988- Richard Feynman passes away at the age of 69 in Los Angeles, California.
The reason he could answer so many questions is that at some point or other he’d worked it out before. He’d have thousands and thousands of pages of notes in a very organized fashion.
