Dave Madden, beloved star of the classic television series "The Partridge Family," has passed away at the age of 83.

Madden played the role of the family's oft put-upon band manager Reuben Kincaid, who often was annoyed by the shenanigans of young Danny, played by former child star Danny Bonaduce.

Madden was also a star on the '70s show "Laugh-In." 

Madden's former agent confirmed his passing to TMZ and told the site that the ailing actor passed away in Florida, where he lived with his wife, after a long struggle with illness.

Aside from his role on "The Partridge Family," alongside fellow stars like Danny Bonaduce, Shirley Jones and David Cassidy, Madden made guest appearances on classic shows, such as "Bewitched," "The Love Boat," "Happy Days" and "Fantasy Island."

He also had a recurring role on the series "Alice" as one of the customers at Mel's diner and as Tommy's basketball coach. He later appeared on "The New Leave It to Beaver," "Boy Meets World," "The Ben Stiller Show" and "Married ... with Children." His last appearance was in an episode of "Sabrina, the Teenage Witch" as Dr. Hans Egglehoffer in 1998.
