Biografia

Duggan's wife, Elizabeth Logue (aka Betty Duggan), died from cancer in Santa Monica, California, on June 7, 1988, less than a month after his death from the same disease. She was a dancer and actress from New York, born on August 10, 1932. They had three children together: Richard, Nancy, and Melissa.

After having a cancerous lump removed from his vocal chords Duggan acquired a raspy voice which enabled him to have a lucrative career doing both voice-overs and TV commercials.

Often played men older than he was. He was only 13 and 14 years older, respectively, than James Stacy and Wayne Maunder, who played his sons in Lancer (1968).

He was the voice of Father/Narrator in the second generation 1975 Carousel of Progress, the first version to premiere in Walt Disney World. Rex Allen was the original Father for the 64/65 World's Fair Carousel of Progress which was later moved to Disneyland in 1967.

At least 32 characters played by Duggan were in the professions (judges, doctors, LEOs, and religious figures), more than 28 were military officers (generals, colonels, captains, majors, etc.), and 5 or more characters were historical United States presidents, including Dwight D. Eisenhower (portrayed three times) and Lyndon B. Johnson (portrayed once).
