Today’s Hero of Progress is Louis Pasteur, a 19th century French scientist, who is commonly dubbed the “father of microbiology.” Pasteur is renowned for developing the germ theory of disease, creating the process of pasteurization (which prevents the spoiling of many food products), and for changing the way that …

Louis Pasteur

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.

Joseph Meister (21 February 1876 – 24 June 1940) was the first person to be inoculated against rabies by Louis Pasteur, and the first person to be successfully treated for the infection. In 1885, nine-year-old Meister was badly bitten by a rabid dog.

Answer: Pasteur was studying samples of saliva from rabid animals as he was trying to develop a vaccine against rabies. He was looking for the rabies microbe in the saliva and trying to isolate it to study the microbes and eventually develop vaccine. 3.

A French chemist, Louis Pasteur (1822–95), is often called the founder of microbiology.

Rabies appears to have originated in the Old World, the first epizootic in the New World occurring in Boston in 1768. It spread from there, over the next few years, to various other states, as well as to the French West Indies, eventually becoming common all across North America.

Answer. Answer: Figure: Louis Pasteur’s spontaneous generation experiment illustrates the fact that the spoilage of liquid was caused by particles in the air rather than the air itself. These experiments were important pieces of evidence supporting the idea of germ theory of disease.

Microbiology has played an essential role in the development and foundation of modern science from the middle of the 19th century. The proof of microorganisms as the real etiological agents of infectious diseases marks the zenith of the period between 1850 and 1915 known as the Golden Age of Microbiology.

Pasteurization is important because the bacteria naturally found in some foods can make you very sick. Eating unpasteurized foods can lead to fever, vomiting and diarrhea. In some cases it can lead to conditions like kidney failure, miscarriage and even death.
