On January 26, 1971, the chemist Friedrich Feigl died in Rio de Janeiro.
Feigl completed his habilitation in analytical and inorganic chemistry at the University of Vienna in 1926 and was appointed associate professor in 1936. He was considered one of the pioneers of chemical microanalysis and the use of organic reagents in analytical chemistry.
Feigl was persecuted under National Socialism for racist reasons and expelled from the University of Vienna in 1938. After emigrating to Belgium, he was arrested in 1940, but was able to escape from a French internment camp to Brazil, where he worked as a laboratory manager in the Ministry of Agriculture with the evaluation of mineral resources. In 1953 he became professor of chemistry in Rio de Janeiro. He returned to Austria in 1961. In 1967 he received an honorary doctorate from the Philosophical Faculty of the University of Vienna.
