Origins
The word "hologram" was coined in 1949 by Hungarian-British physicist Dennis Gabor, who combined Greek "holos" (whole, entire) with "gramma" (something written or recorded).โโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโ Gabor chose this name because his invention captured the whole information of a light field โ both amplitude and phase โ unlike conventional photography, which records only light intensity. He received the 1971 Nobel Prize in Physics for this work.
Greek "holos" traces to Proto-Indo-European *solhโ-wo- (whole, intact), a root with an unexpected English family. Latin "salvus" (safe, uninjured) descends from the same source, giving us "save," "safe," "salvation," "salute," and "salvo." The connection between "whole" and "safe" makes intuitive sense โ something intact is something unharmed.
