• Toothmarks left in birch bark tar suggest people in Finland chewed gum 5,000
years ago.
• The ancient Aztec people in Central America made rubbery glues with natural
chicle from trees.
• The ancient Greeks chewed gum made out of the resin from the mastic tree
thousands of years ago.
• Native Americans chewed a gum made from the sap of spruce trees. European
settlers picked up this practice in the 1800s.
• John B. Curtis created and marketed the first commercial chewing gum in 1848.
It was called The State of Maine Pure Spruce Gum.
• In 1850, a sweetened form of paraffin wax was introduced. It soon became more
popular than the spruce gum.
• An American named William F. Semple was the first person to patent chewing
gum. His gum contained chalk and licorice root. It was not a candy; it was
designed to clean teeth and strengthen one’s jaw!
• In the 1860s, John Colgan created the first flavored chewing gum. He made gum
using extract from balsam trees and sugar. Later on, he made gum from chicle.
• By the early 1870s, chicle was widely used as a chewing gum base and the
number of chewing gum products grew rapidly. Some of the first were Adams
New York Chewing Gum (1871), Black Jack (1884), and Chiclets (1899).
• In the early 1900s, synthetic gum started replacing natural chicle.
• By the mid-1900s, gum manufacturers switched to a synthetic rubber made from
butadiene because it lasted longer and was less expensive than natural chicle.
Butadiene-based gum is still the most common type of gum made today.
