John Quincy Adams
Way back, and we mean way, way back in history when the intelligence quotient or IQ test as we know it was implemented, there were some brilliant people who were also very brave. One was the sixth president of the United States, John Quincy Adams, who was noted as having an IQ of 175.

This Harvard graduate is at the tippy top of all presidents when comparing IQ scores. He traveled and studied all around the world, could speak fluently in seven languages, and became a lawyer without ever completing law school! Presidents use their intelligence and passion to make changes that will go down in history. It takes a high IQ and a lifetime of persistence and confidence to make the White House your home.
