Károly Than

Károly Than , also Carl von Than , (born December 20, 1834 in Bečej , then Austria-Hungary; † July 5, 1908 in Budapest ) was a Hungarian chemist .

Life

Carl von Than took part in the Hungarian Revolution of 1848/49 and then went on to become a pharmacist while attending grammar school at the same time. From 1855 he studied chemistry and pharmacy at the University of Vienna and received his doctorate there in 1858 under Josef Redtenbacher . As a post-doctoral student he was briefly at the University of Heidelberg with Robert Bunsen and in Paris with Charles Adolphe Wurtz and then from 1858 assistant to Redtenbacher in Vienna. In 1859 he became a private lecturer in Vienna and in 1860 he became a full professor of chemistry at the Technical University of Budapest. The Hungarian language had previously been introduced there and Theodor Wertheim , who was previously a chemistry professor, had moved to Graz. In Budapest he was the most important teacher for the following generations of chemists and built a modern chemical institute there. In 1908 he retired.

Carl von Than dealt particularly with analytical chemistry. He recommended potassium iodate (in iodometry ) and potassium hydrogen carbonate (in acid-base titration ) as primary titer substances . In the results of mineral analyzes, he introduced information in ions instead of the previously used information in salts. He discovered carbonyl sulfide in a mineral spring in 1867 and synthesized it for the first time (from thiocyanic acid ).

In 1868 he received the Lieben Prize . He founded the first Hungarian journal for chemistry (Magyar Chémiai Folyóirat) and was president of the Hungarian Society for Natural Sciences from 1872 until his death.

He had been married since 1872 and had five children. In 1908 he was made a baron.
