Linguistic Origin & Historical Etymology

Derived from the surname of Guillaume Duchenne, a 19th-century French neurologist who pioneered the study of facial electrophysiology. He identified the specific contraction of the zygomaticus major and orbicularis oculi muscles that characterizes a genuine, heartfelt smile involving the eyes, as opposed to a deliberate social smile.
