Bohuslav Brauner

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

Life

His father was the Prague lawyer and politician Franz August Brauner . He studied first at the Czech Polytechnic and from 1873 chemistry at the University of Prague. In 1878/79 he was in Heidelberg with Bunsen and Eduard Linnemann to learn inorganic chemistry. It was here that his lifelong rare earth studies began . After completing his doctorate in Prague in 1880, he went to Manchester to study with Henry Enfield Roscoe . The tests carried out in the laboratory showed that the didymium , which was previously considered an element, can be broken down into several components. In 1908 this should lead to a priority dispute with Carl Auer von Welsbach .

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

He made contributions to the confirmation and expansion of the periodic table published by Mendeleev . In 1884 he determined the atomic weight of beryllium. He also worked on rare earths and determined their atomic masses. In 1902 he deduced from the great difference in the atomic masses of the elements neodymium and samarium that an element 61 was missing in between.
