In the time period of 1819-1820, two chemists had been exposed to a pungent displeasing odour, which turned to be a white solid that had been imitative from purifying coal tar (distillation) (Acess Science,14) . In the following year, another chemist, with the name of John Kidd studied the white solid intensely. In 1821, he declared the means of the production, the physical and chemical properties of what we call naphthalene today. When this chemical compound was first discovered, it was known to be naphthaline, mocked from the term naphtha. Not long after, a 4th man, in the physics and chemistry field by the name of Michael Faraday, a pioneer of modern electromagnetic theory, gave Naphthalene a molecular formula, of C10H8 consisting of 10 carbon atoms, and 8 hydrogen atoms. 40 years later, a German chemist, Emil Erlenmeyer proposed the structure of two fused benzene rings. Shorty after, his theory was confirmed, by another German chemist, Carl Gräbe. As the years went on two different moth balls were created. One brand consisted of the main ingredient as naphthalene, while the other was paradichlorobenzene. Paradichlorobenzene was found after many events of naphthalene being set on fire forming huge flames. Naphthalene was then used in areas that consisted of smoke such as cigarette smoke, fossil fuels etc. The ideas of both mothballs were that they were able to kill the moths with their burly fumes. Both the ingredients sublimate and the gas that is released is toxic to the moths. Thus after 50+ years of research on naphthalene and a few years on paradichlorobenzene, mothballs of different kinds were invented putting a stop to Tineola Bisselliella from entering into your house and into your closet chewing you attire.
