Bohuslav Brauner

Bohuslav Brauner ( born May 8, 1855 in Prague, † February 15, 1935 ) was a Czech chemist.

Life

His father was the Prague lawyer and politician Franz August Brauner. He studied at the Czech Polytechnic University and from 1873 Chemistry at the University of Prague. 1878/79 he was in Heidelberg under Bunsen and Eduard Linnemann to learn inorganic chemistry. Here he began his lifelong studies of the rare earths. After he received his PhD in 1880 in Prague, he went to Manchester to Henry Enfield Roscoe. The activities carried out in the laboratory tests showed that the Didym previously applied as an element can be broken down into several components. The 1908 should result in a priority dispute with Carl Auer von Welsbach.

1882/83 he was in Prague lecturer, lecturer in 1885 and 1890 assistant professor. From 1897 to 1925 he was professor of chemistry at the University of Prague.

He has contributed to confirm and extend published by Mendeleev periodic table. In 1884 he determined the atomic weight of beryllium. He also worked on Rare - earth and certain their atomic masses. In 1902, he headed out of the large difference in the atomic masses of the elements neodymium and samarium ago that between one element 61 missing.
