The first discovery of a virus is credited to Dmitri Ivanovsky, a Russian biologist. In 1892, Ivanovsky was investigating a disease affecting tobacco plants known as tobacco mosaic disease. He found that the infectious agent causing the disease could pass through filters that trapped bacteria. This observation led him to conclude that the infectious agent was smaller than bacteria and could not be seen under a light microscope. His work laid the foundation for the concept of a virus, which was later expanded upon by other scientists. While Ivanovsky did not use the term “virus,” his discovery was a significant milestone in the field of microbiology and virology, paving the way for future research into viral diseases and their impact on plants, animals, and humans.
