Dupuy/DePuy

Trevor N. Dupuy (1916-1995) and General William E. DePuy (1919-1992)

I first became acquainted with Trevor Dupuy and his work after seeing an advertisement for his book Numbers, Prediction & War in Simulation Publications, Inc.’s (SPI) Strategy & Tactics war gaming magazine way back in the late 1970s. Although Dupuy was already a prolific military historian, this book brought him to the attention of an audience outside of the insular world of the U.S. government military operations research and analysis community.

Ever since, however, Trevor Dupuy has been occasionally been confused with one of his contemporaries, U.S. Army General William E. DePuy. DePuy was notable in his own right, primarily as the first commander of the U.S. Army Training and Doctrine Command (TRADOC) from 1973 to 1977, and as one of the driving intellectual forces behind the effort to reorient the U.S. Army back to conventional warfare following the Vietnam War.

The two men had a great deal in common. They were born within three years of one another and both served in the U.S. Army during World War II. Both possessed an analytical bent and each made significant contributions to institutional and public debates about combat and warfare in the late 20th century. Given that they tilled the same topical fields at about the same time, it does not seem too odd that they were mistaken for each other.

Perhaps the most enduring link between the two men has been a shared name, though they spelled and pronounced it differently. The surname Dupuy is of medieval French origin and has been traced back to LePuy, France, in the province of Languedoc. It has several variant spellings, including DePuy and Dupuis. The traditional French pronunciation is “do-PWEE.” This is how Trevor Dupuy said his name.

However, following French immigration to North America beginning in the 17th century, the name evolved an anglicized spelling, DePuy (or sometimes Depew), and pronunciation, “deh-PEW.” This is the way General DePuy said it.

It is this pronunciation difference in conversation that has tipped me off personally to the occasional confusion in identities. Though rare these days, it still occurs. While this is a historical footnote, it still seems worth gently noting that Trevor Dupuy and William DePuy were two different people.
