Lothrop Stoddard was a famous racist whom Margaret Sanger actively engaged to work with her organizations. Stoddard became a best-selling author with The Rising Tide of Color Against White World Supremacy. The text contained such inflammatory statements as the following:
“‘Finally perish!’ That is the exact alternative which confronts the white race…. Just as we isolate the bacterial invasions, and starve out the bacteria, by limiting the area and amount of their food supply, so we can compel an inferior race to remain in its native habitat…”
Lothrop Stoddard, The Rising Tide of Color Against White World Supremacy (New York: Charles Scribner’s Sons, 1926), 303, 306, quoted in Edwin Black, op. cit., 133
He worked with Sanger’s American Birth Control League (an early incarnation of Planned Parenthood) in the following capacities: he was on the National Council, the fifteen-member Board of Directors, and on the conference committee of the First American Birth Control Conference and by publishing eugenic articles in the Birth Control Review (for example, in the December 1921 issue).
