Dr. Joseph Lawrence, the creator of LISTERINE® mouthwash, wanted to name his work after a scientist who paved the way. Lister, an English doctor and surgeon, became the first surgeon to perform an operation in a chamber sterilized with pulverized antiseptic. The result? More patients survived than ever before. Inspired, Lawrence created a unique formulation of his own that was perfect for killing germs in tissues, like your mouth.
