Historical• Harmful agents were called viruses (Latin virus, poison or venom) in the nineteenth century• Louis Pasteur used the term virus to describe any living disease causing agent• In 1892,Dimitri Ivanowski gave the first clear evidence of viruses.He observed that leaf extract of infected plant could induce tobacco mosaic disease. Although diseases caused by viruses have been known since the 1700s and cures for many were (somewhat later) effected, the causative agent was not closely examined until 1892, when a Russian bacteriologist, D. Ivanovski, Karl Landsteiner (1868-1943) Karl Landsteiner (1868-1943) and Erwin Popper proved that poliomyelitis was caused by a virus. This was acheived in 8 years. FOOT. 4 Billion Years Ago. The history of virology – the scientific study of viruses and the infections they cause – began in the closing years of the 19th century. • Independent entities - or maybe they just evolved from the self-replicating molecules believed to have existed in the primitive prebiotic 'RNA world' along a parallel course to cellular organisms. • Stanley successfully isolated TMV in pure crystalline state, he concluded that it must be protein or special class of enzyme.

Rain forms pools containing many organic molecules and the first simple life forms appear. 1950s. The discovery of bacteriophages was a landmark in the history of virology, as it meant that for the first time it was relatively easy to work with viruses: many kinds of bacteria could be grown in solid or liquid culture quite easily, and the life cycle of the viruses could be studied in detail. Independent entities maybe these early viruses evolved from the self replicating molecules, believed to have existed in the primitive prebiotic 'RNA world' along a parallel course to cellular organisms. Felix d'Herelle (1873-1949) Following Frederick Twort's work, Felix d'Herelle independently recognizes viruses which infect bacteria, which he called bacteriophages (eaters of bacteria). On the primeval Earth, the surface of the planet is just cooling and beginning to harden into a crust. The Year 1950 André Lwoff (1902-1994) Louis Siminovitch and Niels Kjeldgaard discovered lysogenic bacteriophages in Bacillus megaterium irradiated with ultra-violet light and coined the term prophage.
