The next time you munch on a bag of delicious potato chip, you are
snacking on one of the world's most popular snacks and guess what? It
was invented by a black man.
"Back in those days, African Americans were not allowed to take out patents on their inventions" says Grant-Britton, author of the textbook Holt African American History, so it was never patented. Crum didn't live long enough to see his invention become a popular grocery store item by Herman Lay begenning in 1895.
