Austrian scholar Karl Landsteiner first describe blood group. He began to work on this topic since 1900. He found that no aggregation phenomenon could be found when he put his own erythrocyte and blood serum together in a test tube; when he mixed together erythrocyte and blood serum sourced from different individuals, there might be aggregation or no aggregation. This phenomenon was once observed by many people, but he was the only person who gave it an explanation. Erythrocyte has two kinds of specific structures that may exist alone or together. Blood serum has the antibody called agglutinin of specific structure in erythrocyte; when agglutinin meets with the specific structure in erythrocyte, aggregation will happen, which might be very dangerous when a person is on process of blood transfusion.

How are blood groups different?
Experiments with blood transfusions, the transfer of blood or blood components into a person's blood stream, have been carried out for hundreds of years. Many patients have died and it was not until 1901, when the Austrian Karl Landsteiner discovered human blood groups, that blood transfusions became safer. Mixing blood from two individuals can lead to blood clumping or agglutination. The clumped red cells can crack and cause toxic reactions. This can have fatal consequences. Karl Landsteiner discovered that blood clumping was an immunological reaction which occurs when the receiver of a blood transfusion has antibodies against the donor blood cells. Karl Landsteiner's work made it possible to determine blood groups and thus paved the way for blood transfusions to be carried out safely. For this discovery he was awarded the Nobel Prize in Physiology or Medicine in 1930.
Are blood groups effect fitness?
No. Blood groups are inherited from your parents.
Which scientist discovered human blood groups?
In the year 1900, an Austrian Scientist, Karl Landsteiner, discovered iso-agglutination, the phenomenon wherein red corpuscles and serum of the animal species are clumped together. On carrying out further experiments on blood, Landsteiner discovered that agglutinogens when mixed with agglutinins of another blood types produced fatal agglutination. These agglutinogens were named as A and B, and their respective agglutinins were named alpha and beta respectively. With this discovery, the question of blood group incompatibility was explained. Later, he discovered another blood type and named it O. In 1907, another scientist Jansky discovered a fourth type of blood, it was named AB. This discovery was corroborated by Moss in 1910. These agglutinogens and agglutins were renamed as antigens and antibodies respectively, specific to the blood.

Why is it important to know your blood groups and the blood groups of your family members?
In case any of you need an emergency blood transfer.

The ABO blood group system was discovered in 1900 by Karl Landsteiner. The AB blood group was discovered by Von Decastellor and Sturli in 1902.
What William Harvey discovery?
William Harvey's discovery was limited because:•Doctors could not make blood transfusions until they discovered blood groups in 1901. •Many thought that his idea was mad. •Some Doctors ignored his theory.
