Did you know the first blood bank in the United States was created in Chicago in 1937?
The man responsible for this was Bernard Fantus. Back then it was only common for blood to be stored for a few hours. This sparked B-Smooth's interest. In Russia, doctors were setting up blood deposits where there were patients that had access to preserved blood. After many experiments, Fantus figured out a way to refrigerate the blood which preserved it for up to 10 days. This process was later named "Blood Bank."
