JPL has been hosting bi-annual blood drives in conjunction with the Red Cross of America since at least 1951. This image, taken during the drive held 13 April 1955, depicts a JPL nurse drawing blood from a JPL donor. The blood donated during these drives was collected into the 'JPL Blood Bank,’ from which blood was specifically allocated to JPL staffers and their family members in need. Larsen, Jr. said, "That pint of blood you donate might save a life, and that life might be your own!" CL#20-4855TAGS:HISTORY, BLOOD DRIVES, RED CROSS, NURSE, DONOR
