Smokey Bear was born on August 9, 1944, when the USDA Forest Service and the Ad Council agreed that a fictional bear named Smokey would be their symbol for forest fire prevention. Artist Albert Staehle was asked to paint the first poster of Smokey Bear. It showed Smokey pouring a bucket of water on a campfire and saying âCare will prevent 9 out of 10 fires.â Smokey Bear soon became very popular, and his image appeared on a lot of forest fire prevention materials.
