BRAUNER, BOHLISLAV (1855— ), Czech chemist, was born May 8 1855, at Prague. He studied chemistry at Prague and also under Bunsen at Heidelberg and Roscoe in Manchester, where, in 1881, he was elected Berkeley fellow of Owens college. In 1883, he was appointed lecturer and in 1890 professor of chem istry at the Czech University of Prague. Brauner devoted himself mainly to the field of modern inorganic chemistry, with special reference to the grouping of the elements in Mendeleyev's periodic system, and did important work on the atomic weights and chem istry of the rare elements. He became a fellow of the Bohemian Scientific Society, a member of the Czech Academy, and a cor responding member of the American Academy of Science.
The results of his extensive chemical research have been issued in numerous publications, the chief of which are as follows: On Fluores cence (1877) ; On the Atomic Weight of Beryllium (1878 and 1880 ; Contributions to the Chemistry of the Rare Earths (1882 and 1883) ; On the Atomic Weight of Cerium (1885) ; Experimental Studies on the Periodic Law (1889) ; On the Volumetric Determination of Tellurium (189o) ; On the Constitution of Certain Metallic Chlorides (1889) ; Observations on Argon (1895) ; A Method of Preparing Argon in Large Quantities (1895) ; Revision of the Atomic Weight of Cerium
