Previous historical accounts have considered Drew's resignation of his directorship in March 1941 as a protest by an African American against a Red Cross and military edict that ordered blood supplies be separated by race. Although evidence suggests that Drew voiced displeasure at the racial mandate, his departure was also shaped by the desire to pursue a surgical and teaching career at Howard University. Drew died in an automobile accident in 1950.
