Einstein's Life:
World War II.
¥The government of the United States started to prepare for nuclear warfare. 
¥Einstein did not play any role in the nuclear bomb program of the United States (he was denied a security clearance based on his German background).
¥Einstein continued his quest to develop a truly unified theory of physics.  This quest would dominate his efforts until his death.
