Franklin D. Roosevelt is one of the most celebrated former presidents, with good reason. His 146 IQ also makes him one of the smartest ever.
Abraham Lincoln had an IQ of 148, meaning that he wasn’t just one of the smartest presidents - he was one of the smartest people, period, of his day. Lincoln lived in a time where a formal education didn’t come easy, so the fact that he was able to hone his mental ability to such a staggering degree is really impressive in its own right.
If the only reason you know Chester A. Arthur was the 21st president is because he’s name checked in Die Hard With a Vengeance, you’re not alone. However, this isn’t the most notable thing to ever happen to him - he also had an IQ of 148.
Teddy Roosevelt may only be the second most popular Roosevelt president, but he’s the smartest. So he’s got that going for him, which is nice.
Woodrow Wilson’s 152 IQ means that there were approximately only about 1500 people smarter than him at the time he was president.
