When you think of New Orleans, you're probably thinking of good music, good food, and Mardi Gras, but the Big Easy is home to many other popular inventions. Such as...

Dental Floss

In 1815, a New Orleans dentist by the name of Levi Spear Parmly got tired of seeing his patients come in with cavities and advanced gum disease. A pioneer in the field of preventative dentistry, Parmly invented the modern flossing technique and popularized flossing with easily accessible silk thread, which was strong but slick. A few years later, he wrote the book A Practical Guide To The Management Of Teeth, which influenced the American public to brush twice a day and floss daily.

Venetian Blinds

The story of Venetian blinds has surprisingly little to do with Venice, as they were thought to have been originally conceived in Persia, popularized in France, and patented in England in the mid 1700s. However, it wasn't until 1841 that New Orleans inventor John Hampson figured out how to slant the blinds upon pulling the cord so that they close in on each other, granting more control over the amount of light in the room, which was probably pretty useful during those hot Louisiana summers. These types of blinds are still widely used and sold today.
