Here is the letter I wrote to FDR.  In it I stated my intents to help the U.S. win the second World War by using the atomic bomb.

Because of my Jewish heritage, I was concerned about the possibility about the Germans forming the atomic bomb.  Because of this, I wrote to Franklin Roosevelt that I knew how to make the atomic bomb. Read more on this website:

In 1938, three chemists working in a laboratory in Berlin made a discovery that would alter the course of history: they split the uranium atom. The energy released when this splitting, or fission, occurs is tremendous--enough to power a bomb. But before such a weapon could be built, numerous technical problems had to be overcome.

When Einstein learned that the Germans might succeed in solving these problems, he wrote to President Franklin Roosevelt with his concerns. Einstein's 1939 letter helped initiate the U.S. effort to build an atomic bomb, but work proceeded slowly at first. Two other findings in 1940 and 1941 demonstrated conclusively that the bomb was feasible and made building the bomb a top priority for the United States: the determination of the "critical mass" of uranium needed and the confirmation that plutonium could undergo fission and be used in a bomb. In December 1941, the government launched the Manhattan Project, the scientific and military undertaking to develop the bomb.

A Letter to the President

In August 1939, Einstein wrote to U.S. President Franklin Roosevelt to warn him that the Nazis were working on a new and powerful weapon: an atomic bomb. Fellow physicist Leo Szilard urged Einstein to send the letter and helped him draft it.

Einstein: A Security Risk

In July 1940, the U.S. Army Intelligence office denied Einstein the security clearance needed to work on the Manhattan Project. The hundreds of scientists on the project were forbidden from consulting with Einstein, because the left-leaning political activist was deemed a potential security risk.

The Bombing of Japan

On August 9, 1945, the United States dropped an atomic bomb on the city of Nagasaki, Japan, three days after bombing Hiroshima. By the end of 1945, an estimated 200,000 people had died in the two cities.

Einstein and the Nuclear Age

Although he never worked directly on the atomic bomb, Einstein is often incorrectly associated with the advent of nuclear weapons. His famous equation E=mc2 explains the energy released in an atomic bomb but doesn't explain how to build one. He repeatedly reminded people, "I do not consider myself the father of the release of atomic energy. My part in it was quite indirect." Nevertheless, Einstein was frequently asked to explain his role-as he was when a Japanese magazine editor asked him, "Why did you cooperate in the production of atomic bombs, knowing full well their...destructive power?"

Einstein's answer was always that his only act had been to write to President Roosevelt suggesting that the United States research atomic weapons before the Germans harnessed this deadly technology. He came to regret taking even this step. In an interview with Newsweek magazine, he said that "had I known that the Germans would not succeed in developing an atomic bomb, I would have done nothing."

You might assume that I passed every class I took with great ease.  However, I was a very troublesome boy during my school years.  When I was 15, one of my teachers suggested that I left the school.  I took the suggestion and never came back to that school.

As a young boy, I have always had a fond joy for music. I loved the playing the violin because my mother was a musician as well. Some of my favorite musicians of all time were Mozart, Bach, and Beethoven. I played my violin that I named Lina when brainstorming and I often played in public.

When I first met Mileva Marić, I thought she was the love of my life.  Because of this, we married in 1903.  What you may not know about me is that Mileva and I had an illegitimate child that either died or was given up for adoption.  I will leave the fate of my Liesrel a mystery.  After Liesrel, the Einstein generation continued when my two sons, Hans Albert, and Eduard.  My poor little Hans sadly had to go to a mental asylum.  Later on in my life in 1919, Mileva and I went through a tough divorce.  Later on however, I married my first cousin Elsa Einstein.  People always told me this wasn't normal but I believe that you can love anyone including family members.

I finally finished the great Theory of Relativity.  My first thought on relativity was a dream that I had when I was 16 about chasing a beam of light and here I am finally saying that I finished it.  From my first thoughts of relativity in 1896 to my favorite accomplishment today in 1915 that I will lovingly call the Theory of Relativity.  In case you don't have a love of science like I do, the Theory of Relativity determines that the laws of physics created by Isaac Newton are the same for all non-accelerating observers.  I also proved that the speed of an object is the same no matter how fast or slow the speed of the observer is.  Soon because of this books, will be written about me.  They'll be called Einstein His Life and Universe and I'll be known across the world.
