1898 – 1964
Leó Szilárd (11 February 1898 – 30 May 1964) was a Hungarian-American physicist, and probably the first scientist to take seriously the idea of actually developing atomic bombs; he drafted the famous letter sent by Albert Einstein to U.S. President Franklin Delano Roosevelt that was largely responsible for initiating the Manhattan Project to develop nuclear weapons during World War II.

The ten commandments according to Leó Szilárd
1. Recognize the connections of things and laws of conduct of men, so that you may know what you are doing.
2. Let your acts be directed toward a worthy goal, but do not ask if they will reach it; they are to be models and examples, not means to an end.
3. Speak to all men as you do to yourself, with no concern for the effect you make, so that you do not shut them out from your world; lest in isolation the meaning of life slips out of sight and you lose the belief in the perfection of creation.
4. Do not destroy what you cannot create.
5. Touch no dish, except that you are hungry.
6. Do not covet what you cannot have.
7. Do not lie without need.
8. Honor children. Listen reverently to their words and speak to them with infinite love.
9.Do your work for six years; but in the seventh, go into solitude or among strangers, so that the memory of your friends does not hinder you from being what you have become.
10. Lead your life with a gentle hand and be ready to leave whenever you are called.
