Book Review:
Blood Relations: The Rise and Fall of the Du Ponts of Delaware
Barbara Klaw
By Leonard Mosley
It is hard to read the history of America since 1800 without
running into du Ponts. The first patriarch helped Jefferson
negotiate the Louisiana Purchase; generations later, du
Ponts designed the first secret atomic plants in World War II.
5 The family business has provided gunpowder of increasing
sophistication for all of America’s wars from 1812 on, and du
Pont chemists have produced dozens of items as
indispensable in our lives as cellophane and nylon.
10 That we know less about individual du Ponts than about
Rockefellers or Vanderbilts, Mosley says in this highly
entertaining history of the dynasty, is because self-appointed
family archivists and the company’s “tight-lipped public
relations men” have for years sanitized the record. Only
15 recently have scholars been permitted to poke around in
family papers.
The first Pierre Samuel du Pont advocated marriage between
cousins to ensure “honesty of soul and purity of blood.”
20 Several generations later, the reigning patriarch was
grumbling that “the thinning” of that pure blood by inbreeding
was producing freaks. But the intermarrying cousins, most of
them clustered around the original family holdings on the
Brandywine River, went right on producing scores of little
25 Pierre Samuels, Alfreds, and Irénées with the typical long du
Pont noses, and the family disposition toward tuberculosis.
By the 1920’s, the close Delaware clan was the richest family
in America.
30 Mosley’s lively chronicle weaves together a sweeping
business history—well larded with corporate dirty tricks—
and the personal stories of dozens of du Ponts, the
honorable ones, the stuffy ones, and the outrageous ones.
The family may regret that they ever let the scholars in.
