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.
