Born east of Longmont, in Weld County, Guy D. Duncan was the first Colorado native to serve Boulder County as District Attorney. In 1885, he graduated from the University of Colorado and then attended the University of Michigan where he obtained his law degree in 1891.

Duncan was admitted to the bar in 1892 and returned to Boulder where he set up a general law practice. Beginning in 1895, he served as Deputy District Attorney under Adam C. Patton.

In 1900, when Duncan ran for District Attorney of the Eighth Judicial District, the Greeley Tribune stated: “We feel safe in making the statement that Mr. Duncan does not keep a private jug of whiskey in his office, that he does not invite men to his office to drink with him intending thus to influence their votes, and that he has left no unpaid old liquor bills to come up now at this day to haunt him in his candidacy.”

Duncan, seated on the right, was photographed in Boulder during an 1899 meeting of the Chautauqua Board of Directors.
