Daniel J. Travanti (born Danielo Giovanni Travanti, March 7, 1940) is an American actor best known for his starring role as Captain Frank Furillo in the 1980s television drama Hill Street Blues.

Travanti, one of five children, was born in Kenosha, Wisconsin, to Italian immigrant parents. His father worked at the American Motors assembly plant in that city. During his teen years, Travanti was an athlete and good student, earning scholarships to Harvard University, Princeton University, and Dartmouth College, although he eventually attended the University of Wisconsin-Madison.[1]

In 1957, before his senior year of high school, he attended the youth government and leadership program called Badger Boys State.[citation needed]

His first credited role was in an episode of Route 66 called "Child of a Night". In 1964, Travanti guest-starred in the episode "Murder by Scandal" of CBS's drama about newspapers, The Reporter. He made his feature film debut in 1965 (credited as "Dan Travanty") playing a deaf mute nightclub bouncer in the psychological thriller Who Killed Teddy Bear? starring Sal Mineo and Juliet Prowse.

In 1966 he played the role of radio talk show host and murderer Barney Austin in the Perry Mason episode, "The Case of the Midnight Howler".

Travanti has publicly acknowledged his past as an alcoholic[2] who found sobriety through Alcoholics Anonymous, calling alcoholism a "disease of loneliness and secrecy". In 1981, he made such a confession to Rona Barrett in an interview on NBC and even recited, from memory, all of the organization's "Twelve Steps" on camera.[3] Captain Furillo, his best-known character, was also a recovering alcoholic, and the character was shown multiple times taking part in AA meetings.
