chemist and
microbiologist.
He is known for his
discoveries of principles
of vaccination, microbial

5. He reduced the mortality from puerperal
fever.
He created first vaccines for rabies and
anthrax.
His medical discoveries provided direct

He is best known for his invention of the
technique of treating milk & wine by gentle
heating to stop bacterial contamination, a
process now called pasteurization.

7. Pasteur also made significant
discoveries in chemistry, most notably
on the molecular basis for the
asymmetry of certain crystals and
racemization.
He is known as the ‘Father of
modern microbiology’.

8. 2. Robert Koch
Born : 11 December, 1843
Died : 27 May, 1910
Country: Germany
Known for : Discovery of
bacteriology
Koch’s

germ theory,
Isolation of
anthrax,
tuberculosis,
and cholera

9. He was a German physician and pioneering
microbiologist.
He is
best known
for giving
four
postulates,
now called
Koch’s
postulates.

10. He discovered the
causative agent of anthrax –
Bacillus anthracis.
Koch determined the
causative agent of cholera,
isolating Vibrio cholerae.
He reported the causative
agent of tuberculosis –
Mycobacterium
tuberculosis.
