Roeblingite is a calcium manganese lead silicate sulfate mineral originally discovered at Franklin, New Jersey (Penfield and Foote, 1897). The name honors Colonel Washington Augustus Roebling (1837-1926), of Trenton, New Jersey, USA, American civil engineer who built the Brooklyn Bridge. Roebling was an avid mineral collector, and his collection went to the Smithsonian Institution. The composition of roeblingite remained in question until the crystal structure solution of Moore and Shen (1984). Roeblingite here forms a porcelain like mass, 9 by 4 mm, with phlogopite-hendricksite and xonotlite
