Charles Drew was a physician, surgeon and medical researcher who invented the refrigerated trucks that are used to this day to transport blood between locations, known as bloodmobiles or mobile blood donation centers.

  • Drew played a seminal role in creating and developing the first large-scale blood banks and blood plasma programs during World War II and worked with the Red Cross on new developments in blood transfusions, which saved thousands of lives during the war.
  • He eventually resigned from the American Red Cross because of the organization's racist insistence on segregating blood.
