Why Is Blanka Wladislaw Influential?
(Suggest an Edit or Addition)According to Wikipedia, Blanka Wladislaw was a Brazilian chemist of Polish-Jewish descent. Biography Wladislaw was born Blanka Wertheim on 3 June 1917, in Warsaw, Congress Poland, a part of the Russian Empire. Her family emigrated to Brazil when she was 14, where they have faced great financial difficulty on their arrival in São Paulo. She decided to dedicate herself to her studies in order to enter the University of São Paulo and in 1937 accomplished this, entering the university's Faculty of Philosophy, Sciences and Letters and graduated in 1941. Wladislaw's professional career began when she was hired by , but she was determined to go to graduate school. In 1949, she completed her doctorate with her thesis analyzing the behavior of various sulfur compounds in presesence of Raney nickel catalysts, advisor Heinrich Hauptmann, and joined the Faculty of Philosophy, Sciences, and Letters as an assistant to Hauptmann.
