George Washington Carver in brief
George Washington Carver was born into slavery in Missouri in the early 1860s. Freed after the Civil War, he worked his way through school, was refused by one college because he was Black, and studied botany at Iowa State, earning a master's degree in 1896. Booker T. Washington then hired him at the Tuskegee Institute in Alabama, where he spent nearly fifty years teaching farmers crop rotation and new uses for peanuts and sweet potatoes. He died in 1943.
What was George Washington Carver's IQ?
No figure exists. LifeScore lists about 140 as an editorial marker, range 125 to 155. It rests on his self-driven education after slavery, a master's degree in botany and decades of applied agricultural research and teaching.
Did George Washington Carver invent peanut butter?
No. Peanut butter existed before his work. He did promote peanuts as a crop and published bulletins listing many products and recipes from peanuts, sweet potatoes and soybeans, which gave rise to the popular claim of 300 peanut uses.
Why is Carver important?
Cotton had exhausted Southern soils. Carver taught farmers to rotate cotton with nitrogen-fixing crops such as peanuts and sweet potatoes, and found uses for those crops so farmers could sell them. He became one of the most famous Black Americans of his time.
Did Carver patent his products?
He held only three patents, for cosmetics and paints made from peanuts and clay. He said his ideas came from God and that he should not profit from them, so most of his methods were published openly in bulletins written for farmers.

How Carver thought
Carver turned a problem, worn-out soil, into a system: rotate crops, then create markets for the new crops. He also translated science into plain advice for farmers who had little schooling, which takes real verbal and practical intelligence.
The evidence behind the estimate
An estimate built from the historical record, not a recovered test score.
What supports it
- He earned a master's degree from Iowa State in 1896.
- He testified to the US Congress in 1921 on the value of peanuts.
- His Tuskegee bulletins are preserved and document his work.
What it cannot prove
- Popular legends exaggerate his inventions, which can distort assessments.
- His career faced severe racial barriers.
- An editorial marker is a comparison aid built from achievement, not a measurement, and two careful readers could place it ten points apart.
