Question

Who was the first to identify a virus, in this case, the tobacco mosaic virus. If there is more than one I would like to know them too​

Answer 1

Answer:

Dmitry Ivanovsky

Explanation:

The discovery of viruses is attributed to Dmitry Ivanovsky, a Russian microbiologist who, between 1887 and 1890, investigated the mosaic disease of tobacco plants occurring in Eastern Europe. He found that the disease-causing factor passed through a porcelain filter that had pores fine enough to hold back bacteria.
