In 1887 , Dmitry Ivanovsky started his research work on Tobacco Mosaic Disease which then led to the first discovery of virus . He had a groundbreaking idea and came up with the idea of using Chamberlin's Candle to filter the sap of Tobacco plant. After filtering the sap, Ivanovsky injected the sap into healthy tobacco leaves. Once the healthy plants began to show signs of infection, Ivanovsky proved that bacterial filtering of disease sap did not prevent the disease, and thus the infective organism had to be unlike any bacteria that they had seen before. Beijernick coined the term 'virus' which means an infective agent that can cause harm and may even lead to death.

Viruses was first discovered by Dmitry Ivanovsky in 1892. He was still a student when he began his work on tobacco Mosaic disease later renamed to be Tobacco Mosiac viruse that led to the first discovered of viruse

Viruses were first discovered after the invention of a porcelain filter—the Chamberland-Pasteur filter—that could remove all bacteria visible in the microscope from any liquid . In 1886, Adolph Meyer discovered that a disease of tobacco plants[tobacco mosaic disease]could be transferred from a diseased plant to a healthy one via liquid plant extracts.

The scientist were   Dmitri Ivanovsky  who discovers virus in 1892. It's meaning is
1.

an infective agent that typically consists of a nucleic acid molecule in a protein coat, is too small to be seen by light microscopy, and is able to multiply only within the living cells of a host. It contains RNA

How were viruses discovered?
After coming to this question we all always start come stop here. Well viruses are very diverse to have a look in it. There were two scientist who discovered virus. The very first virus that was discovered was tobacco mosaic virus, in 1982. Some extracts from infected leaves, they did some filtrations and found the term virus.

Virus was first discovered by Dmitri Ivanowsky in 1892. He filtered the sap of the plants infected with it. He told it to be the reason for tobacco mosaic disease. In 1898 M.W. Beijerinek called the filter ‘Contagium vivum fluidum’ and named it the ‘virus’.

Dimitrii Ivanovsky while researching on tobacco mosaic disease noticed that an agent after removing from the infectious tobacco leaves even after filtering it thoroughly remained infectious. Ivanovski did not grasp the meaning immediately. Beijerinck was the first one to call the 'contagium vivium fluidum' a virus. The tobacco mosaic virus was the first virus to be found.

Summary: In 1897, Beijerinck found the latin name ‘virus’ Which means poison
He studied and tried on healthy plants and found out that the virus made the plants sick

The discovery of viruses was discovered by Dmitry Ivanovsky, a Russian microbiologist who, between 1887 and 1890, investigated the mosaic disease of tobacco plants occurring in Eastern Europe.

Discovery of virus

There were two scientists who contributed the discovery of virus called Tobacco mosaic virus. Ivanoski used a filter to show about the sap that was diseased. By that filter the bacteria could be removed but the disease couldn't be removed. This led to the discovery of viruses. Virus means a poisonous agent.

# data[].attributes.body
The first evidence of virus existence came from experiments with filters that had pores small enough to retain bacteria. 1892, Dmitri Ivanovsky used one of the filters to show the sap from a diseased tobacco plants remained infections to healthy plants even after been filtered.

In Starting all were confused but in the end when they saw their size is it smaller then bacteri and it was small so they decided that it is virus

Two decades of work on tobacco mosaic disease by three botanical scientists. It took them 20 years to implicate their implictions and then they found viruses.
