In 1901 Karl Landsteiner discovered that when the Blood of one human being was transfused with that of another human being, differences in their Blood might well be the cause of shock, jaundice, and the Blood disorder hemoglobinuria that had resulted through earlier Blood transfusions.
Landsteiner classified human Blood into A, B, and O groups and demonstrated that transfusions between humans of group A or B did not result in the destruction of new Blood cells and that this catastrophe occurred only when a person was transfused with the Blood of a person belonging to a different group. A fourth main Blood type, AB was found in 1902 by A. Decastrello and A. Sturli.
From that time, differing Blood typing systems have been devised. Historically the naming of Blood grouping systems has been disorganized. The common conventions stipulating that dominant traits be given capital letters and recessive traits be designated with lower case letters have not been followed. Also by tradition, red cell antigens were given alphabetical designations or were named after the family of the antibody producer.

I know some people, especially in the armed forces that tape their blood type to their boot...just in case they don't make it back alive
“All day I think about it, then at night I say it. Where did I come from, and what am I supposed to be doing? I have no idea. My soul is from elsewhere, I'm sure of that, and I intend to end up there.”
Yes i think it is now? But i know a few that still do it. Why i don't know? I know some who even have a letter to their family in their pocket just in case they don't make it The one who finds them is supposed to send it to their family...That would be so hard for me to do
