The earliest indications of the biological nature of viruses came from studies in 1892 by the Russian scientist Dmitry I. Ivanovsky and in 1898 by the
Dutch scientist Martinus W. Beijerinck. Beijerinck first surmised that the
virus under study was a new kind of infectious agent, which he designated
contagium vivum fluidum, meaning that it was a live, reproducing organism that
differed from other organisms. Both of these investigators found that a disease of tobacco plants could be transmitted by an agent, later called tobacco
mosaic virus, passing through a minute filter that would not allow the passage of bacteria. This virus and those subsequently isolated would not grow
on an artificial medium and were not visible under the light microscope. In
independent studies in 1915 by the British investigator Frederick W. Twort
and 1917 by the French Canadian scientist Félix H. d’Hérelle, lesions in
cultures of bacteria were discovered and attributed to an agent called bacteriophage (“eater of bacteria’’), now known to be viruses that specifically infect
bacteria
