His contributions…
🔸Dr. Karl Landsteiner was born in a suburb of Vienna in a middle-class family. He studied medicine at the University of Vienna and graduated in the year 1891. He envisioned that the future of medicine was in research.
🔸Hence he interacted with many European scientists and got trained. Then he returned to Vienna University in 1897 and started his research in the emerging field of Immunology.
🔸At the Institute of Pathological Anatomy in Vienna, he performed nearly four thousand post-mortem examinations and published over seventy-five articles. Out of 75 articles, 55 are serological studies. He also studied the interactions between red blood cells and serum in different healthy individuals.
🔸After an extensive research, he announced his discoveries of three major blood group A, B, C (C was later called as O) in 1901. Subsequently, one of his students discovered the fourth blood group – AB – in 1902.
🔸He was the first to describe that the human blood contains different antigens and immune properties and also confirmed that blood clumping was an immunological reaction.
🔸Further, he had made another scientific breakthrough by discovering the Rh-factor in blood, which he named after Rhesus monkeys that he used for research.
🔸His ABO blood group system was quickly adopted and saved many injured soldiers of the First World War by blood transfusions.
🔸In addition, he extended his support in identifying the pathological organism causing Poliomyelitis by conducting an autopsy of a patient who died of polio and discovered that virus is responsible for the disease, not the bacteria. He also introduced dark-field microscope to identify the causative organism of Syphilis.
🔸In 1920s, he became the Emeritus Professor at the Rockefeller Institute for Medical Research in New York City, where he continued his research in immunity.
🔸In 1930, he was honoured with Nobel Prize in Medicine or Physiology for his great discovery of major Blood groups and creating the ABO blood group system.
🔸He compiled his contributions in medicine and published a book, “The Specificity of Serological Reactions” in 1936, which was a classic textbook that helped to establish the field of Immunochemistry.
🔸His birthday (June 14) was declared as World Blood Donor Day. The theme of 2022 is “Donating blood is an act of solidarity. Join the effort and save lives.”
