Jöns Jacob Berzelius, a Swedish chemist, is credited with introducing the modern system of chemical symbols for elements around 1813. He proposed using one or two letters from the Latin name of the element, with the first letter capitalized and the second lowercase (if present). This system is the basis of the symbols used today in the periodic table.

The modern notation of using one or two letters derived from the element’s name as its symbol was proposed by Berzelius.

John Dalton used unique pictorial symbols for elements in his atomic theory. Antoine Lavoisier contributed significantly to the understanding of elements and chemical nomenclature but did not introduce the system of letter symbols. Robert Boyle is known for his definition of an element in “The Sceptical Chymist” and Boyle’s Law related to gases, but not for introducing element symbols.
