Abraham Lincoln | 150

Abraham Lincoln had an impressive IQ of 150, even though he only had very little formal schooling. He was largely self-taught and, as everyone who studies history knows, became a lawyer and a US president. His accomplishments as president include leading the Union in the Civil War and abolishing slavery through the Emancipation Proclamation. A gifted speaker, he also delivered what is considered the most iconic presidential speech in US history, the Gettysburg Address. While he never got to see the end of the war, Lincoln left a legacy. He was an honest leader and a sharp military strategist.

Long before becoming president, Lincoln ran a tavern located in Illinois. However, his business did not last long because of debt, so he later abandoned the booze for law books. Who knew a former bartender could become a barrister and a nation’s leader?
