**Abraham, Anton Franz (ca.1850-1926 ) was a mineral dealer in Vienna, Austria. He started in business with his partner, Clemens Hartwich, as the "Naturhistorisches Institut" on Beatrixgasse at least as early as 1896, and they moved to new quarters on Ungargasse in 1903-1906. At some time after 1906 Hartwick left the partnership and Abraham operated thereafter under his own name.

***Prof. Dr. Heinz Meixner (1908-1981). Professor in Mineralogy, Petrology and Economic Geology at the Institute for Mineralogy at the University of Salzburg. Dr Meixner was the best expert on mineralogy in Austria (Pfaffl, 1986). Meixnerite was named after him.
