Did You Know: Seaborgium was the first element named for a person while he was still alive. The name einsteinium had been proposed while Einstein was still alive, but not approved until after his death.
There are 21 elements named after people (element eponyms), although the International Union of Pure and Applied Chemistry (IUPAC) sometimes considers the connection to a person to be indirect. In other words, sometimes the element name was chosen to honor a place or thing, indirectly connecting it to someone’s name.
Fun Fact: No one has ever named an element after himself!
