Kenneth Harry Dahlberg (June 30, 1917 – October 4, 2011) was an American businessman and highly decorated World War II fighter ace.

Born in Saint Paul, Minnesota, Dahlberg grew up on a farm near the village of Wilson, Wisconsin and attended classes in a one-room school for 11 years.

He eventually became an aviation cadet in the United States Army Air Forces (USAAF), where one of his instructors was future Senator Barry Goldwater.

Dardis showed Bernstein a photostatic copy of a cashier's check for $25,000 that had been deposited into the bank account of a real estate firm owned by Bernard Barker, one of the Watergate burglars.

It was later learned that the $25,000 came from Dwayne Andreas, chief executive officer of Archer Daniels Midland, as an anonymous donation to the Nixon campaign.

Woodward has said that finding Dahlberg's check was a turning point in their investigation because it led to the discovery of how the Watergate burglars were financed through a money laundering scheme.

Dahlberg also earned the Silver Star, two Distinguished Flying Crosses, two Purple Hearts, 16 Air Medals, and the French Croix de Guerre.

Dahlberg was a trustee and longtime supporter of the Museum of Flight in Seattle, which named its military aviation history research center for him.

[18] Croix de Guerre with Palm (France) The President of the United States of America, authorized by Act of Congress, July 9, 1918, takes pleasure in presenting the Distinguished Service Cross to Captain (Air Corps) Kenneth H. Dahlberg, United States Army Air Forces, for extraordinary heroism in connection with military operations against an armed enemy while serving as Pilot of a P-47 Fighter Airplane in the 353d Fighter Squadron, 354th Fighter Group, NINTH Air Force, in aerial combat against enemy forces on 19 December 1944, over Germany.

On that date, Captain Dahlberg was serving as flight commander during an armed reconnaissance mission near Trier, Germany, when a formation of more than ninety enemy fighters was observed.

Despite the enemy's vast numerical superiority, Captain Dahlberg led his eight-ship flight in a direct attack upon the hostile force.
