Etymology: Jöns Jacob Berzelius (1779–1848) was a Swedish chemist who did more than almost anyone to fix the modern language of chemistry. He introduced the one- and two-letter element symbols still used today, such as O for oxygen and Fe for iron, replacing the older alchemical circles and pictograms. He also standardized the use of the term "catalysis" and helped establish the idea of isomerism, and he gave chemists a systematic way to write compounds. Because so many of his contributions were named after him, his surname appears in the names of several things, including the mineral berzelianite and the crater Berzelius on the Moon. The word is therefore a proper noun, formed simply from his family name, and it carries no older meaning in the language. Berzelius was a surname of Swedish origin, and the name survives mainly through the scientist, which is why it appears almost exclusively in chemical and scientific contexts rather than in everyday speech.
