Etymology: Ciechanover is a Polish-Jewish surname, and it is best known as the name of Aaron Ciechanover, the Israeli biochemist who shared the 2004 Nobel Prize in Chemistry with Avram Hershko and Irwin Rose for discovering how cells tag proteins for destruction with ubiquitin. The name itself is a toponymic surname, taken from a place name: "Ciechanów" is a town in north-central Poland, and "Ciechanowiec" (in what is now Belarus) is another. Surnames of this kind were commonly formed from a town name plus a suffix meaning "a person from" that place, which is why many Polish and Jewish families bear names built from towns. Because the name is a regional family surname rather than a common word, its meaning is simply the place it came from. The root "Ciechan-" is generally linked to the Polish word for a warm or sheltered place, but that connection is uncertain, and the surname's direct meaning remains tied to the towns that bore the name.
