Teitelbaum (טײטלבױם teytlboym, deriving from a Yiddish/Germanic word meaning date palm) is a Jewish surname. http://www.encyclopedia.com/topic/Alfred_Tarski.aspx "Tarski was the son of Ignacy Tajtelbaum, a successful shopkeeper, and his wife, Rose Prussak Tajtelbaum. (Around 1924 he changed his name from Tajtelbaum to Tarski—to protect his as yet unborn children from anti-Semitism.)" R. Paul quotes from wiki: Tarski, "a name they invented because it sounded more Polish, was simple to spell and pronounce, and seemed unused." The source goes on: "(Years later, Alfred met another Alfred Tarski in northern California.)" The point is whether this Alfred Tarski was also originally Tajtelbaum. I doubt it. In which case, while "Tarski" IS an Invented Surname, it only SEEMED unused but it wasn't.
