Biography
After an apprenticeship in pharmacy, he studied chemistry and crystallography at the University of Berlin, where his influences were Eilhard Mitscherlich, Heinrich Rose, Christian Samuel Weiss and Gustav Rose. His graduate thesis in 1837 dealt with cyanogen, "De cyanogenii connubiis nonnullis". In 1841 he became a privatdozent at the university, and in 1845 was named an associate professor of inorganic chemistry. From 1850 he taught classes at the Gewerbeakademie, a vocational training academy that was a predecessor of the Technical University of Berlin. In 1874 he became a full professor of chemistry at the university and in 1883 was appointed director of the inorganic chemistry laboratory.
He distinguished himself with research in the fields of mineralogy, crystallography, analytical chemistry and metallurgy. He discovered the reducing action of hypophosphoric and phosphoric acids, and was the first scientist to determine the composition of Schlippe's salt (sodium thioantimonate). In addition, he made significant contributions in research involving isomorphism.
He described the minerals, magnesioferrite and tachyhydrite. Rammelsbergite, a nickel arsenide mineral, is named after him. He died at Gross Lichterfelde, southwest of Berlin
