Tobacco mosaic virus (TMV) is an RNA virus that infects plants, especially tobacco and other members of the family Solanaceae. The infection causes characteristic patterns (mottling and discoloration) on the leaves (hence the name). TMV was the first virus to be discovered. Although it was known from the late 19th century that an infectious disease was damaging tobacco crops, it was not until 1930 that the infectious agent was determined to be a virus.
Please improve this answer if you know exactly how he discovered this virus.
What else can I help you with?
Who first characterize a virus?
Dmitri Ivanovsky and Martinus Beijerinck are often credited with the first characterization of a virus in the late 19th and early 20th centuries through their work on tobacco mosaic disease. They discovered that the causal agent, which was smaller than bacteria and could pass through filters that trapped bacteria, was a new type of infectious agent that they called a "virus."
Who coined the term virus?
There had been theories that there were infectious agents smaller than bacteria but it had not been proven until the first plant virus was discovered in 1898, tobacco mosaic virus, by the Martinus Beijerinck. The experiments continued, and animal viruses, as well as plant viruses, were grown in labs on eggs and animal tissues by several scientists. Cow pox was one of the early animal viruses isolated. Then in 1913, E. Steinhardt, C. Israeli and R. A. Lambert were able to isolate and grow the vaccinia virus, a virus that was a human poxvirus. This was the first virus used to create a vaccine and was how small pox was eradicated (the first human disease that scientists were able to eliminate). Vaccines and vaccinations get their names from this work with the vaccinia virus. It was an extension of their work that also enabled the vaccines for poliovirus to be developed in the 1950's. The first time a human virus was actually seen, was when electron microscopy was invented and used in 1931 by two German engineers, Ernst Ruska and Max Knoll, to make the first ever images of viruses.
How did the work of ivanovsky and beijerinck lead to the discovery of the virus?
Ivanovsky and Beijerinck independently discovered that an infectious agent smaller than bacteria was causing disease in plants. Their work laid the foundation for the concept of viruses as distinct entities from bacteria, leading to further research and the eventual identification and characterization of viruses.
Which virus was crystallized for the first time?
Tobacco mosaic virus was the first virus to be crystallized in 1935 by Wendell Stanley.
What was the first virus to be isolated?
The first virus to be isolated and identified was the tobacco mosaic virus in 1892 by Russian scientist Dmitri Ivanovsky.
Who is credited with discovering the virus?
Martinus Beijerinck in 1898.

Who was martinus begrimimg?
he discovered the first virus TMV
What was the first virus ever discovered?
The first actual identification of viruses as a distinct pathogenic agent was by Louis Pasteur, but he did not isolate or classify them. In 1892 Dimitri Ivanovsky was able to separate the toxic agent of the tobacco mosaic virus. In 1898 Martinus Beijerinck determined the virus to be a reproductive particle much smaller than a bacteria. In 1935, Wendell M. Stanley achieved the crystallization of the tobacco mosaic virus, showing that it remained potent despite crystallization, and allowing imaging of a virus for the first time (in 1939). He shared the Nobel Prize for Chemistry in 1946.

Who discovered virus in microorganism?
The first person to use the word "virus" to describe unknown toxins smaller than bacteria was Martinus Beijerinck, although the existence of toxins of this type had been observed earlier through the use of unique bacteria filtration devices. He used the word "virus" because he assumed the toxin was a soluble fluid of some type ("virus" is Latin for poison/venom). It was not until later that Wendell Stanley proved that viruses were solids, and much later the electron microscope was able to show that they had complicated structures.
What has the author Jacobus Martinus Kaper written?
Jacobus Martinus Kaper has written: 'The chemical basis of virus structure, dissociation and reassembly'
How was the virus discovered?
Viruses were identified as non-bacterial toxic agents by many researchers beginning with Louis Pasteur in the 1870's, Charles Chamberland in 1884, and Dimitri Ivanovsky in 1892. Viruses were different because they could penetrate filters that stopped bacteria. Martinus Beijerinck defined the virus as a nucleotide particle rather than a fluid in 1898. It was not until 1935 that Wendell Stanley was able to crystallize viral particles and they were imaged for the first time using an electron microscope in 1939.
What has the author Laurens Martinus Brans written?
