Etymology: "Rosenhan" is a surname, so its history belongs to a family name rather than a coined term. It is most likely German, built from "Rosen," the plural of "Rose," and a second element that may be "Hahn," meaning "rooster." Surnames of this type were often taken from houses, inns or emblems, but the exact origin of this one is uncertain. Its best-known bearer, the psychologist David Rosenhan, gained fame through a study titled "On Being Sane in Insane Places." In it, healthy researchers gained admission to psychiatric hospitals by reporting that they heard voices, then behaved normally and were still kept as patients. The experiment made the surname closely tied to debates about whether clinicians can reliably tell sanity from insanity.
