Yep - The Ice Cream Cone was invented right here in St. Louis during the 1904 World's Fair...
An edible conical shaped cone for serving ice cream was created at the St. Louis World's Fair by Ernest Hamwi in 1904. His waffle booth was next to an ice cream vendor who ran short of dishes. Hamwi rolled a waffle to contain ice cream and the cone was born.
Some St Louis Ingenuity for you!
