Personal Details

• Full Name: Karl Landsteiner
• Birth Date: 14 June 1868
• Birth Place: Vienna, Austria-Hungary (now Austria)
• Death Date: 26 June 1943
• Death Place: New York City, USA

Contributions and Achievements

1. Blood Group System: Landsteiner is best known for discovering the ABO blood group system in 1901. His work identified the different blood types (A, B, AB, and O) and explained the importance of blood compatibility for safe blood transfusions. This discovery was crucial in reducing complications and saving countless lives during medical procedures involving blood transfusion.

2. Nobel Prize: In recognition of his discovery of the ABO blood group system, Karl Landsteiner was awarded the Nobel Prize in Physiology or Medicine in 1930.

3. Rhesus Factor: Landsteiner also played a key role in the discovery of the Rh factor in blood, alongside Alexander S. Wiener in 1940. This discovery further improved the safety and effectiveness of blood transfusions.

4. Poliomyelitis Research: Landsteiner contributed significantly to the understanding of poliomyelitis (polio). In 1908, he and his colleague Erwin Popper demonstrated that polio was caused by a virus, paving the way for future research and the eventual development of a polio vaccine.

5. Immunology and Pathology: Throughout his career, Landsteiner conducted extensive research in immunology and pathology, contributing to the understanding of immune responses and the mechanisms of various diseases.
