Lunsford Richardson was the pharmacist who shifted to Greensboro, North Carolina in 1890. He found that his children kept falling ill and developed a salve containing menthol, eucalyptus oil, camphor, cedar leaf oil, nutmeg oil and thymol to treat them. When the experiment proved successful, he decided to market the salve under the name of his brother-in-law Dr. Joseph Vicks, partly because he was a respected physician and partly because his name was short  enough to fit  on the labels pasted on the jars. Thus came into existence Vicks Vaporub.
