Chemists are scientists who specialize in the field of chemistry. Having said that, the job of a chemist does not limit to a chemistry laboratory alone! Today, with rapid industrialization, almost every industry employs chemists in their industrial set-ups be it pharmaceuticals or plastics, medicine or paints, chemical industry or detergent industry and so on. Chemists generally investigate the chemical nature of substances and observe how they behave under different conditions to search for new knowledge. They examine both organic and inorganic compounds to determine their chemical and physical properties, composition, structure, and reactivity. Chemists try to decode the details of the chemical molecules and their component atoms. It is this knowledge that comes in assistance to comprehend the composition and properties of unknown substances. Over the years, there have been innumerable chemists from every century who have greatly contributed to the society’s chemical future. However, the largest influx in the subject was seen in the 20th century as more and more individuals dedicated themselves to this field of study. 20th century was home to some of most famous and renowned chemists of the era including Dan Shechtman, Derek Barton, Charles J Pederson and Albert Hofmann.
