1886, Fractur, "German black-lettering," from German Fraktur "black-letter, Gothic type," also "a fracture, a break," from Latin fractura (see fracture (n.)). So called from its angular, "broken" letters. The style was common in German printing from c. 1540 and thence was transferred to Pennsylvania German arts that incorporate the lettering.[fraktur etymology, fraktur origin, 英语词源]
