Franklin Pierce – IQ 147.4

Famously touted by Miller Center as someone with ‘limited political ability,’ Franklin Pierce was a US president whose influence in passing the Kansas-Nebraska Act as one of the most important laws in the nation will forever remain a pivotal contribution. Pierce had otherwise quite an uneventful stint in office, and he served only one term.

While many would disagree with his policies, he managed to impact the country’s history significantly. With his above-average IQ, Pierce was a brilliant figure, and it is indeed unfortunate that he did not get to serve a second spell in office.
