2. Thomas Jefferson
Source: Biography.
One of the founding fathers that fought for U.S. independence from the British. He served as head of office between 1801-1809 and was the nation’s third president. He strongly opposed a centralized government.
One of his first policies was to eliminate a highly unpopular tax on whiskey. Quite smart by him, don’t you think? Well, it’s not surprising considering the man (according to recent studies) had an IQ of about 153; that’s 1.5 times the current average global IQ. This man was almost as intelligent as Stephen Hawking (160) and Albert Einstein (estimated 160-190).
