March 15, 1937. The first blood bank opened in the United States of America.
Dr. Bernard Fantus created innovations in storing and transfusing blood in the early 1900s. Due to this, and under Dr. Fantus’ leadership, the first blood bank was opened at Cook County Hospital. Fantus’ blood bank was created in an attempt to be able to easily match patients in need of a transfusion with a matching donor. If you needed a transfusion before this time, there would have had to have been a donor on-site at the time the transfusion was required.
In 1936, there were about six hundred-fifty transfusions. After the blood bland was established, there were over one-thousand-three-hundred-fifty-four transfusions a year later. Today, almost a hundred years later, blood transfusions are vital and always needed.
