One of the earliest forerunners of modern ice cream was a recipe brought back to Italy from China by Marco Polo. The recipe was very like what we would call sherbet. From there, it is thought that Catherine de Medici brought the dessert to France when she married King Henry II in 1533.
The first true edible conical shaped cone for serving ice cream was created at the St. Louis Worlds 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. Paper, glass and metal cones, cups, and dishes were used during the 19th century in France, Germany, and Britain for eating ice cream.
