Post 7: An Expert on your field

Hi everyone, being honest I don't know 
someone on my field at university enough to talk and for my bad luck my chemistry teachers  weren't very good. So I selected a famous chemist on the chemistry history, Hes name  Louis Pasteur, he was bor in France in 18th century, after a lot of degrees he proposed the most influential theory for the health sciences, the Germ theory of disease and the importance of this theory is it has the basis to all the subsequent studies about diseases and vaccines. So if Louis wasn't born the life expectancy would be significantly lower than now a days and the pandemics would be more dangerous, we have to imagine a world without cure for measles, chicken pox, rubella and others infectious diseases. And the covid-19 would be much difficult to be controlled because we wouldn't have the sanitary measures.
