Antal Ruprecht
(Schmöllnitz/Smolnik, now Slovakia, 1748 - Wien (Austria), 1814)

Ruprecht graduated from the Mining Academy of Selmecbánya established in 1763. He was appointed to be professor chemistry and metallurgy in 1779. He was among the first who regarded the so-called "soils" as complex substances, and tried to show this by experiments. He succeeded in melting platinum first and he had a part in the discovery of tellurium.
