Joel Margolis, 69, who produced the halftime shows at Washington Redskins home games, died Dec. 13 at his home in Silver Spring after a heart attack.

Mr. Margolis, who was the Redskins' director of stadium operations, was born in Washington and attended the old McKinley Technical High School.

Among his halftime productions for the Redskins were specials honoring states and musical composers and the annual Santa Claus halftime show at the last Redskins home game before Christmas.

He once brought the National Symphony to the old Griffith Stadium to play at halftime during a Redskins game. He oversaw the weekly practices of the Redskins Marching Band and in 1958 formed the Redskins singers, who still perform at all home games.

In 1961 Mr. Margolis formed the Redskinette cheerleaders.

Mr. Margolis went to work for the old Loew's Capitol Theater as an usher in 1937 and worked his way up to manager before joining the Redskins organization full time in 1961. He had joined the team on a part-time basis in 1949.

Mr. Margolis also had participated in the production of the annual American Legion Stage Shows, the Cherry Blossom Festival shows at the Sylvan Theater, and the Touchdown Club awards dinner.

He was a member of the Elks, the International Order of the Moose, the Touchdown Club and was "Chief Barker" of the Variety Club International.

Survivors include his wife of 48 years, Jeanette, of Silver Spring; a daughter, Diana Joan Kreuzburg of Silver Spring; a son, Donald Lee, of Davis, Calif., and four grandchildren.
