The Heimlich maneuver was named after Dr. Henry Jay Heimlich, who developed the procedure in 1974. That's a German surname originating in fifteenth-century Switzerland which was originally a nickname for a secretive person and comes from an adjective meaning "secret" or "private". -Lich is just an suffix used for forming adjectives (eventually coming from Proto-Germanic likaz and Proto-Indo-European leyg, "like") and heim derives from the Proto-Germanic word haimaz, meaning "home" - the connection was that people do private things in their homes. Finally, that derives from Proto-Indo-European koymos, or "village". After rapidly being popularized in the 1970s and 1980s, literary usage of the phrases Heimlich and Heimlich maneuver peaked in 1995 and have been declining since.
