This is a family story my father told me about his mother, my Grandmother.
In 1949, my father had just returned home from the war. On every American highway you could see soldiers in uniform hitchhiking home to their families , as was the custom at that time in America.
Sadly , the thrill of his reunion with his family was soon overshadowed . my grandmother became very ill and had to be hospitalized. It was her kidneys, and the doctors told my father that she needed a blood transfusion immediately or she would not live through the night . The problem was that Grandmother`s blood type was AB- , a very rare type even today , but even harder to get then because there were no blood banks or air flights to ship blood. All the family members were typed, but not one member was a match . So the doctors gave the family no hope , my grandmother was dying.
