As Americans awoke on June 6, 1944 to news of the Normandy landings, blood donation centers across New York City filled with volunteers eager to help the wounded overseas. Archival photographs show long lines of ordinary citizens responding instantly to the call.
This home‑front mobilization was powered by the groundbreaking work of Dr. Charles Drew, whose innovations in plasma processing allowed blood components to be dried, shipped, and reconstituted near the front. While plasma collected on June 6 would not reach Normandy within mere weeks, it became part of the massive supply pipeline that sustained Allied medical operations throughout the summer campaign.
