Donald Duck and His Nephews

According to interviews by Taliaferro, Huey, Dewey, and Louie were originally named after two political figures and an animator of the time:

Huey was named after Huey Long (1893–1935) of Louisiana.

Dewey was named after Admiral George Dewey (1837–1917) of the Spanish–American War.

Louie was named after animator Louie Schmitt (1908–1993).
