3. Chocolate chip cookies

  • Ruth Graves Wakefield (1903–1977)

This classic American staple was invented in 1930 by Ruth Graves Wakefield, an American chef from Massachusetts. Chocolate chip cookies were actually discovered by mistake in a restaurant owned by Ruth Graves Wakefield, called the Toll House Inn.

Her incredible story is engraved in our minds every time we take a chocolate chip cookie bite. One day, Ruth ran out of baker’s chocolate, which she desperately needed to finish her recipe. She tried to handle the situation with hope; therefore, Ruth swapped baker’s chocolate for a semi-sweet Nestle chocolate bar… and voilà—that’s how chocolate chip cookies were born.

Ruth’s cookies were so popular they increased the sales of Mr. Andrew Nestle’s chocolate bars, touching the heart of every single American.

4. Dental floss

  • Levi Spear Parmly (1790–1859)

All of us have the ability to floss due to Levi Spear Parmly, a dentist from New Orleans who is recognized as the inventor of the first form of dental floss. This major discovery in dentistry was made in 1815, becoming a crucial part of good oral hygiene.

If you want to freshen up your pearly whites, you have several ways to do it, and one of them is dental floss. This item is probably found in the house of every American, making it an indispensable everyday item.

Thank you, doctor Parmly for preventing tooth decay and periodontal disease since 1815!
