The idea to represent elemental names with one- or two-letter symbols was largely developed by the Swedish chemist Jöns Jacob Berzelius in the early 19th century. He standardized the use of symbols for chemical elements, using the first letter of the element's name and, when necessary, the second letter to create a unique abbreviation. This system was later adopted and refined, becoming a universal standard in chemistry.
