Karl Landsteiner, ForMemRS[1] (June 14, 1868 – June 26, 1943), was an Austrian and American biologist and physician.[2] He is noted for having distinguished the main blood groups in 1900, having developed the modern system of classification of blood groups from his identification of the presence of agglutinins in the blood, and having identified, with Alexander S. Wiener, the Rhesus factor, in 1937, thus enabling physicians to transfuse blood without endangering the patient′s life. With Constantin Levaditi and Erwin Popper, he discovered the polio virus in 1909. He received the Aronson Prize in 1926. In 1930, he received the Nobel Prize in Physiology or Medicine. He was awarded with Lasker Award in 1946 posthumously, and is recognized as the father of transfusion medicine.[3]
Start of an academic career[edit]
Landsteiner’s father, Leopold (1818–1875), a renowned Viennese journalist who was editor-in-chief of Die Presse, died at age 56, when Karl was only 6. This led to a close relationship between him and his mother Fanny (née Hess; 1837–1908). After graduating with the Matura exam from a Vienna secondary school, he took up the study of medicine at the University of Vienna and wrote his doctoral thesis in 1891. While still a student he published an essay on the influence of diets on the composition of blood.
From 1891 to 1893, Landsteiner studied chemistry in Würzburg under Hermann Emil Fischer, in München under Eugen Bambergerand in Zürich under Arthur Rudolf Hantzsch. A number of publications from that period, some of them in co-operation with his professors, show that he did not restrict himself to attending lectures.[4]
Research work in Vienna – Discovery of the polio virus[edit]
After returning to Vienna he became an assistant to Max von Gruber at the Hygienic Institute. In his studies he concentrated on the mechanism of immunity and the nature of antibodies. From November 1897 to 1908 Landsteiner was an assistant at the pathological-anatomical institute of the University of Vienna under Anton Weichselbaum, where he published 75 papers, dealing with issues in serology, bacteriology, virology and pathological anatomy. In addition he did some 3,600 autopsies in those ten years. Weichselbaum was Landsteiner’s tutor for his postdoctoral lecture qualification in 1903.[5] From 1908 to 1920 Landsteiner was prosector at the Wilhelminenspital in Vienna and in 1911 he was sworn in as an associate professor of pathological anatomy. During that time he discovered – in co-operation with Erwin Popper – the infectious character of poliomyelitis and isolated the polio virus.[6] In recognition of this groundbreaking discovery, which proved to be the basis for the fight against polio, he was posthumously inducted into the Polio Hall of Fame at Warm Springs, Georgia, which was dedicated in January 1958.
Discovery of the blood groups[edit]
In 1900 Karl Landsteiner found out that the blood of two people under contact agglutinates, and in 1901 he found that this effect was due to contact of blood with blood serum. As a result, he succeeded in identifying the three blood groups A, B and O, which he labelled C, of human blood. Landsteiner also found out that blood transfusion between persons with the same blood group did not lead to the destruction of blood cells, whereas this occurred between persons of different blood groups.[7] Based on his findings, the first[8] successful blood transfusion was performed by Reuben Ottenberg at Mount Sinai Hospital in New York in 1907.
Today it is well known that persons with blood group AB can accept donations of the other blood groups, and that persons with blood group O can donate to all other groups. Individuals with blood group AB are referred to as universal recipients and those with blood group O are known as universal donors. These donor-recipient relationships arise due to the fact that type O blood possesses neither antigens of blood group A nor of blood group B. Therefore the immune systems of persons with blood group A, B or AB do not refuse the donation. Further, because persons with blood group AB do not form antibodies against either the antigens of blood group A or B, they can accept blood from persons with these blood groups, besides from persons with blood group O.
In today’s blood transfusions only concentrates of red blood cells without serum are transmitted, which is of great importance in surgical practice. In 1930 Landsteiner was awarded the Nobel Prize in Physiology or Medicine in recognition of these achievements. For his pioneering work, he is recognized as the father of transfusion medicine.[9]
