Gaspard Bauhin (1560 - 1624 A.D.), a Swiss botanist, was the first taxonomist to suggest the binomial system of nomenclature. He used the binomial nomenclature in his books Prodromus Theatri Botanici (1620) and ?Penax Theatri Botanici? (1623). Later on the system was developed by Carolus Linnaeus (1707-1778) by naming all known species of plants in his book ?Species Plantarum? published in 1753. This established the usage of binomial nomenclature for naming species.
