1936, network of defensive fortifications built along the northern and eastern borders of France before World War II, in which the French placed unreasonable confidence, named for André Maginot (1877-1932), French Minister of War under several governments in the late 1920s and early 1930s. After the fall of France in 1940, for the next 40 years or so the phrase was associated with a mental attitude of obsessive reliance on defense.
by 1779, named for Charles Mason and Jeremiah Dixon, English astronomers who surveyed (1763-7) the disputed boundary between the colonial holdings of the Penns (Pennsylvania) and the Calverts (Maryland). It became the technical boundary between "free" and "slave" states after 1804, when the last slaveholding state above it (New Jersey) passed its abolition act. As the line between "the North" and "the South" in U.S. culture, it is attested by 1834.

fem. proper name, from Greek sōphrōnia, from sōphrōn (genitive sōphrōnos) "discreet, prudent, sensible, having control over sensual desires, moderate, chaste," literally "of sound mind," from sōs "safe, sound, whole" + phrēn "heart, mind" (see phreno-).
