How often do we take out the time to think about those extra ordinary minds who made life easier for us? Raman also worked on the acoustics of musical instruments. He was the first to investigate the harmonic nature of the sound of the Indian drums such as the tabla and the mridangam.

Louis Pasteur , born December 27, , Dole , France—died September 28, , Saint-Cloud , French chemist and microbiologist who was one of the most important founders of medical microbiology. He pioneered the study of molecular asymmetry; discovered that microorganisms cause fermentation and disease; originated the process of pasteurization ; saved the beer , wine , and silk industries in France; and developed vaccines against anthrax and rabies. He also disproved the theory of spontaneous generation and contributed to germ theory and the study of infectious disease. Louis Pasteur is best known for inventing the process that bears his name, pasteurization. Pasteurization kills microbes and prevents spoilage in beer, milk, and other goods. In his work with silkworms, Pasteur developed practices that are still used today for preventing disease in silkworm eggs. Using his germ theory of disease, he also developed vaccines for chicken cholera, anthrax, and rabies.

A scientist is a person who conducts scientific research to advance knowledge in an area of interest. In classical antiquity , there was no real ancient analog of a modern scientist. Instead, philosophers engaged in the philosophical study of nature called natural philosophy , a precursor of natural science. In modern times, many scientists have advanced degrees [6] in an area of science and pursue careers in various sectors of the economy such as academia , industry , government , and nonprofit environments. The roles of "scientists", and their predecessors before the emergence of modern scientific disciplines, have evolved considerably over time. Scientists of different eras and before them, natural philosophers, mathematicians, natural historians, natural theologians, engineers, and others who contributed to the development of science have had widely different places in society, and the social norms , ethical values , and epistemic virtues associated with scientists—and expected of them—have changed over time as well. Accordingly, many different historical figures can be identified as early scientists, depending on which characteristics of modern science are taken to be essential.
