Ralph J. Rossinguolo, 53, an offical of the Veterans Administration and former legislative director of the American Veterans of World War II, Korea and Vietnam, died of cancer Saturday at the Veterans Administration Hospital in Washington.

Mr. Rossignuolo, a native of Chicago, served in the Army in World War II and received the Bronze Star for actioin against the enemy on the Anzio beachhead in Italy. After the war, Mr. Rossinguolo received training in the area of veterans' claims at American University.

He then moved to Iowa to serve as Amvets' state service executive director. He remained in Iowa until 1969, when he was appointed national service and legislative director of Amvets at the headquarters here. Mr. Rossignuolo retired from there in 1971, and joined the voluntary services staff at the Veterans Administration. At the time of his death he was assistant director of policy and planning responsible for interpreting and converting legislation affecting veterans to VA regulations.

Mr. Rossignuolo was a member of the Disabled American Veterans and president of the Wingate Elementary School Parent Teacher's Association.

Survivors include his wife, Mary, four sons, Joel, John, Jerome and James, all of the home in Bethesda; three brothers, Anthony, Frank and Carl, and a sister, Anna Landry, all of Chicago.

The family suggests that expressions of sympathy be in the form of contributions to the American Cancer Society, the Bethesda-Chcvy Chase Rescue Squad or to the AMVETS National Service Foundation.
