Fritz Feigl (15 May 1891 – 23 January 1971) was a Jewish Austrian-born chemist. He taught at the University of Brazil.
Austria, officially the Republic of Austria, is a country in Central Europe comprising 9 federated states. Its capital, largest city and one of nine states is Vienna. Austria has an area of 83,879 km2 (32,386 sq mi), a population of nearly 9 million people and a nominal GDP of $477 billion. It is bordered by the Czech Republic and Germany to the north, Hungary and Slovakia to the east, Slovenia and Italy to the south, and Switzerland and Liechtenstein to the west. The terrain is highly mountainous, lying within the Alps; only 32% of the country is below 500 m (1,640 ft), and its highest point is 3,798 m (12,461 ft). The majority of the population speaks local Bavarian dialects as their native language, and German in its standard form is the country's official language. Other regional languages are Hungarian, Burgenland Croatian, and Slovene.
A chemist is a scientist trained in the study of chemistry. Chemists study the composition of matter and its properties. Chemists carefully describe the properties they study in terms of quantities, with detail on the level of molecules and their component atoms. Chemists carefully measure substance proportions, reaction rates, and other chemical properties. The word 'chemist' is also used to address Pharmacists in Commonwealth English.
Feigl was born and studied in Vienna, but owing to his military service in the First World War he had to interrupt his studies. He received his Ph.D. for work with Wilhelm Schlenk in 1920. After his habilitation in 1928 he became a Professor at the University of Vienna. He was forced to retire after the Nazi occupation of Austria in 1938.
Vienna is the federal capital and largest city of Austria, and one of the nine states of Austria. Vienna is Austria's primate city, with a population of about 1.9 million, and its cultural, economic, and political centre. It is the 7th-largest city by population within city limits in the European Union. Until the beginning of the 20th century, it was the largest German-speaking city in the world, and before the splitting of the Austro-Hungarian Empire in World War I, the city had 2 million inhabitants. Today, it has the second largest number of German speakers after Berlin. Vienna is host to many major international organizations, including the United Nations and OPEC. The city is located in the eastern part of Austria and is close to the borders of the Czech Republic, Slovakia, and Hungary. These regions work together in a European Centrope border region. Along with nearby Bratislava, Vienna forms a metropolitan region with 3 million inhabitants. In 2001, the city centre was designated a UNESCO World Heritage Site. In July 2017 it was moved to the list of World Heritage in Danger.
Wilhelm Johann Schlenk was a German chemist. He was born in Munich and also studied chemistry there. Schlenk succeeded Emil Fischer at the University of Berlin in 1919.
The University of Vienna is a public university located in Vienna, Austria. It was founded by Duke Rudolph IV in 1365 and is the oldest university in the German-speaking world. With its long and rich history, the University of Vienna has developed into one of the largest universities in Europe, and also one of the most renowned, especially in the Humanities. It is associated with 20 Nobel prize winners and has been the academic home to a large number of scholars of historical as well as of academic importance.
Feigl was able to get to Belgium and work there. After the occupation of Belgium he was imprisoned in a concentration camp, but was able to reach Portugal and from there Brazil in 1940.
He worked at the University of Rio de Janeiro and became a Brazilian citizen in 1944.
Fritz Feigl is the creator of "spot analysis" (spot test),a simple and efficient technique where analytic assays are executed in only one, or a few drops, of a chemical solution, preferably in a great piece of filter paper, without using any sophisticated instrumentation. A notable example he developed was a simple test to know if fishes eaten by Amazon population are contaminated by lead. Poor populations by the Amazon rivers were taught to easily use that technique to find out contaminated fishes and discharge them.
Spot analysis, spot test analysis, or spot test is a chemical test, a simple and efficient technique where analytic assays are executed in only one, or a few drops, of a chemical solution, preferably in a great piece of filter paper, without using any sophisticated instrumentation. The development and popularization of the test is credited to Fritz Feigl.
On the occasion of Feigl's 70th birthday the Chemical Society of Midland sponsored a symposium in 1962, attended by 500 scientists from 24 countries, in which all plenary sessions were related on spot tests.
A less known contribution is the development of "luminol", a substance used by forensic investigators to detect presence of blood, even if the scene is washed and cleaned.[ citation needed ]
Luminol (C8H7N3O2) is a chemical that exhibits chemiluminescence, with a blue glow, when mixed with an appropriate oxidizing agent. Luminol is a white-to-pale-yellow crystalline solid that is soluble in most polar organic solvents, but insoluble in water.
Carl Bosch was a German chemist and engineer and Nobel Laureate in Chemistry. He was a pioneer in the field of high-pressure industrial chemistry and founder of IG Farben, at one point the world's largest chemical company.
Fritz Pregl, was a Slovenian and Austrian chemist and physician from a mixed Slovene-German-speaking background. He won the Nobel Prize in Chemistry in 1923 for making important contributions to quantitative organic microanalysis, one of which was the improvement of the combustion train technique for elemental analysis.
Richard Johann Kuhn was an Austrian-German biochemist who was awarded the Nobel Prize in Chemistry in 1938 "for his work on carotenoids and vitamins".
Friedrich Adolf Paneth was an Austrian-born British chemist. Fleeing the Nazis, he escaped to Britain. He became a naturalized British citizen in 1939. After the war, Paneth returned to Germany to become director of the Max Planck Institute for Chemistry in 1953. He was considered the greatest authority of his time on volatile hydrides and also made important contributions to the study of the stratosphere.

The Haitinger Prize of the Austrian Academy of Sciences was founded in 1904 by the chemist and factory director, Ludwig Camillo Haitinger (1860-1945), who created the award in honor of his father, Karl Ludwig Haitinger. From 1905 to 1943 it was awarded every year, for "studies in chemistry and physics that proved to be of great practical use for industrial applications". The prize was awarded for the last time in the year 1954.
