History

Etymology

Borrowed from French Mascon, from Medieval Latin Masconis, a syncopated form of Madasconis and Matisco, probably from Gaulish matus (“bear”) (from Proto-Celtic *matus, commonly understood as a euphemistic derivation from *matis (“good”)) and a suffix equivalent to -iscus (“-ish: forming adjectives”).

Blend of mass + concentration in 1960s by scientists Paul Muller and William Sjogren.
