A true scientist endures the deprivation of his chosen path, and James Marshall is undoubtedly the most true scientist.

The scientific community did not take his theory seriously that stomach ulcer is not caused by stress or spicy food, but by the microbe Helicobacter pylori.

To prove that he was right, Marshall identified, cultivated and drank a culture of an open bacterium. He could wait for months and years to develop a ulcer, but then he was lucky - a week later he got sick, and his stomach was sick from pain.

Guided by his theory, he began taking antibiotics and soon recovered.

Thus, James Marshall in 1984 not only proved the pathogenicity of H. pylori, but also discovered a new way to treat gastritis.

From a distinctive doctor, he immediately turned into a world globe of science, which institutes and large companies from all over the world wanted to get to themselves.

In 2005, Marshall was awarded the Nobel Prize in Medicine.
