Reuben Kincaid and the Professor, yikes, tough day. Via the Associated Press report -- “The Partridge Family,” which ran on ABC from September 1970 to March 1974, revolved around a widowed mother and her five children who form a band. Towering and rumpled, Mr. Madden played Reuben Kincaid, the agent who managed the band and regularly clashed with its impish preteen bassist, played by Danny Bonaduce. The series starred Shirley Jones, with her real-life son David Cassidy as the resident heartthrob. But it was Mr. Madden and the freckle-faced Mr. Bonaduce who were the reigning comic duo. “His relationship with Danny Bonaduce is what made the show work,” Ms. Jones said of Mr. Madden on Thursday, “this strange, mad little boy and the grown man who was even worse as a father figure.” Though Mr. Madden played a man bedeviled by the youngsters surrounding him, off camera he “loved kids,” Ms. Jones said. Mr. Bonaduce later wrote that during his troubled youth Mr. Madden served as his surrogate father.
