Who invented blood group ?

The blood group was invented by Karl Landsteiner. Karl Landsteiner was born on June 14, 1868 in Vienna. Karl’s father, Leopold Landsteiner, a prominent newspaper publisher and editor who died when Karl was six years old, was a doctor of law. Carl was raised by his mother, Fanny Hayes, whom he loved so much that he hung his death mask on the wall until he died. After graduating from high school in 1891, Landsteiner studied medicine at the University of Vienna. He began to study biochemical as a student and in 1891 released a study on the effect of nutrition on blood ash composition. He spent the following five years at the laboratories of Hantzsch in Zurich, Emil Fischer in Würzburg, and E. Baumberger in Munich, studying more about chemistry.

Blood group scientist name is Karl Landsteiner.

After returning to Vienna, Landsteiner resumed his medical studies at the Vienna General Hospital. He began working as an assistant at Max von Gruber’s Sanitary Institute in Vienna in 1896. He was already fascinated by the mechanics of immunity and the nature of antibodies at that time. From 1898 to 1908, he was a professor in the Department of Pathological Anatomy at the University of Vienna. Together with Frenkel, Axelbaum explored the bacterial aetiology of meningitis and pneumococcus. Landsteiner focuses on morbid physiology rather than morbid anatomy. Despite some criticism from within the institute, Wechselbaum supported him. In 1908, Wechselbaum was named prosecutor of the Wilhelminaspital in Vienna, where he remained until 1919. In 1911 he was appointed Professor of Pathological Anatomy at the University of Vienna, although his salary was not there.
After twenty years of study on pathological anatomy with several partners, Landsteiner had by 1919 published several publications on his results in morbid anatomy and immunology.They discovered fresh information about syphilis immunology, which improved our understanding of the Wassermann reaction, as well as immunological components known as haptens (later discovered that were used in this reaction). The active chemicals in the extracts of the common organ were, in fact, haptens). Were). He made a significant contribution to our knowledge of paroxysmal hemoglobinuria.

He also established that the cause of poliomyelitis could be transmitted to monkeys by injecting material produced by crushing the spinal cord of infants who died of the disease, and when they ran out of Vienna Monkeys, in Paris, Gaya. Found by Pasteur. went to the institute. To continue your research. Their work with Flexner and Lewis laid the foundation for our current understanding of poliomyelitis aetiology and immunology.

He made many contributions to pathological anatomy, histology and immunology, all of which demonstrated his biological understanding as well as his painstaking observation and description. But he will undoubtedly be remembered for his 1901 discovery of blood types and for his remarkable work, for which he was awarded the 1930 Nobel Prize in Physiology or Medicine.

When humans receive blood transfusions from other animals, foreign blood cells collide in the human blood vessels and break, releasing hemoglobin, as Landois discovered in 1875. In 1901–1903, Landsteiner proposed that a similar reaction may occur when the blood of a human is transfused with the blood of another human instead of the blood of an animal, and this may have been the reason for previous attempts at blood transfusion. could. could. This results in shock, jaundice and hemoglobinuria.

His ideas were ignored until 1909, when he classified human blood into the now well-known A, B, AB and O groups, demonstrating that infection between individuals in groups A and B did not result in the destruction of new blood cells. This catastrophe happens only when a person is transfused with blood from a person of another group. In 1901–1903 Landsteiner first proposed that because the characteristics that make up the blood group are inherited, blood groups could be used to identify paternity in cases of dispute. Not in Vienna, but in New York, Landsteiner and his students did much of their work on blood groups and their immunological applications. Because laboratory work in Vienna in 1919 was extremely difficult, and Landsteiner saw no future for Austria, he was appointed prosecutor of a small Roman Catholic hospital in The Hague. He published twelve publications on new haptens between 1919 and 1922, he discovered conjugates with proteins capable of reducing allergies and related difficulties, as well as the serological specificity of hemoglobin from various animal species. When he was offered a position at the Rockefeller Institute for Medical Research in New York, he accepted it and moved to New York with his family. It was here that he worked with Levine and Wiener on blood groups, significantly increasing the number of these groups, and where he investigated bleeding in newborns with Wiener, resulting in the discovery of the Rh-factor in the blood of humans. And combines the rhesus monkey blood.

Landsteiner worked until the end of his life on blood groups and the chemistry of antigens, antibodies, and other immunological components found in blood. One of his many achievements was the inclusion of chemistry in the field of serology.

Karl Landsteiner was a tireless worker who was careful in his expectations. He was a frequent observer of subjects other than those in which his major work was carried out throughout his life (for example, he was responsible for introducing dark-field light into the study of spirochetes). He wanted to be alone because he was depressed by nature.

In 1916, Landsteiner married Helen Wlasto. Dr. E. Landsteiner is the result of this association.

In 1939, he was named emeritus professor at the Rockefeller Institute, yet he continued to work as hard as ever following scientific developments. He had a pipette in his hand, which was special to him. He suffered a heart attack in his laboratory on June 24, 1943, and died two days later in the institute’s hospital, where he had done such remarkable work.
