He left the portraits of his sisters and mother, but , due to the enthusiasm chemistry, paint thrown.

Early Years

received a Bachelor of Arts ( 1840 ) and

a Bachelor of Science ( 1842 ) at the Ecole Normale shkole.
Paster became a professor of chemistry at the University of Strasbourg , where he met in 1849 and began courting Marie Laurent , daughter of the rector of the university.
May 29, 1849 they were married , married with five children were born , but only two of them survived to adulthood (the other three died of typhoid fever ) .

studied the properties of tartaric acid.
After this work

Pasteur was appointed associate professor of physics at Dijon Lyceum, but three months later, in May 1849, at the invitation went associate professor of chemistry at the University of Strasbourg.

Work in the field of chemistry

Pasteur proved that fermentation is a process closely related

to the activity of the yeast that feed and reproduce by fermenting liquid.
At the same time, Louis Pasteur made ​​another important discovery.
He found that there are organisms that can live without oxygen.

The study of fermentation

of spontaneous generation of microorganisms.
He spent a fantastic
