Publicist Adeline Hanson, who co-founded the Hanson & Schwam Public Relations, died Saturday of leukemia at the Motion Picture Country Hospital in Woodland Hills. She was 81.

A native of Minnesota, she began her career as a publicist representing jazz musicians and performers while hosting a daily radio show in Los Angeles. She later hosted a weekly music TV show on KTLA-TV where she interviewed film composers, arrangers and recording artists. In the early 1950s, she worked as a columnist for the old Los Angeles Daily News.

She and Gene Schwam joined forces in 1955 to form Hanson & Schwam, which has since become the longest-running entertainment PR partnership in the history of the industry.

Under her stewardship, the agency represented some of music’s outstanding performers and artists, including Quincy Jones, Benny Carter, Nancy Wilson, Ray Charles, Red Norvo and many others.

Her roster of clients also included Oscar-winning film composers such as Hugo Friedhofer, Jerry Goldsmith, Henry Mancini, Ernest Gold and Alex North. In addition to the agency’s music and personal appearance division, she was active in the firm’s film and TV departments until her retirement in 1985.

A funeral service will be held 12:30 p.m. today at Forest Lawn Hollywood Hills’ Faith Chapel.
