The origin of little trees, a scent-sational journey

The video tutorial explores the history and development of automotive air fresheners, focusing on Julius Simon's pivotal role. Over 60 years ago, Simon, a chemist, was inspired by a milkman's complaint about spoiled milk odors. Drawing from his research on Alpine tree aromas, Simon patented a tree-shaped paper infused with air perfume in 1954. This innovation led to the creation of Little Trees, which became a global success. The company has since sold over a billion units worldwide, with scents continually evolving while maintaining the iconic tree shape.
