Who invented the air freshener?

The concept of air fresheners has existed for centuries. However, the invention of the modern air freshener is credited to Julius Sämann. Sämann was a German perfumer who lived in Chicago during the early 20th century. In the 1930s, he created the first air freshener, which he marketed under the name "Air Wick". Air Wick was originally a liquid that was vaporized by heat from a light bulb.
