1. In 1576, Charles Encluse was the first to realize the existence of viruses.
2. In 1796, scientist Edward Jenner mentioned the viral spring fever.
3. In 1886, Dutch scientist Adolf Mayer was the first to see tobacco leaf spot mosaic disease.
4. In 1892 Russian scientist Dmitri Ivanovsky proved that tobacco leaf germs can be filtered by antibacterial filters and that the germs are smaller than bacteria. He called it Virum. Hence Ivanovsky is called the discoverer of viruses.
5. In 1898, scientist Martinus Beijerinck named the tobacco leaf pathogen Tobacco Mosaic Virus (TMV).
6. In 1901, scientist Walter Reed first discovered the virus that causes human yellow fever or jaundice.
7. In 1931, German engineers Ernst Ruska and Max Knoll were the first to photograph viruses using an electron microscope.
8. In 1935, American scientist Wendel Meredith Stanley isolated TMV from tobacco. For this he won the Nobel Prize in 1946. Stanley isolated just one teaspoon of virus crystals from a ton of tobacco leaves. Dr. Siddiq Publications
9. In 1936-1937 scientists F. C. Bawden and N. W. Pirie proved that viruses are composed of nucleic acids and proteins.
10. In 1941, Bernal and Funkuchen obtained X-ray diffraction images of chelated viruses. Based on this image, Rosalind Franklin discovered the complete structure of the virus in 1955.
11. In 1951, R. S. Shafferman and M. E. Morris discovered cyanophages that destroy cyanobacteria.
12. In 1952 scientist A. Lwoff said – A virus is a virus. It is neither a living organism nor a non-living chemical, but something in between. That is, a virus is a virus. It is neither living matter nor inert chemical matter. A virus is a type of organism between living and non-living things.
14. In 1965, scientist Howard Temin discovered retroviruses.
15. In 1984, scientist Gallow discovered HIV, the virus that causes the deadly human disease AIDS. Later, successive scientists Gallo, Sinousi and Montanier discovered two types of HIV.
16. In 1989, scientist Hervey J. Alter discovered the silent killer hepatitis C.
17. In late 2019, the Novel Corona Virus or Covid-19 was discovered.
13. In 1963, scientist Baruch Blumberg discovered Hepatitis-B. Dr. Siddiq Publications
