BELFAST, Northern Ireland (AP) _ Sir Ian Fraser, a pioneer in using penicillin to treat battle wounds during World War II, has died at age 98.

Fraser died at his home on Tuesday, his family said. The cause of death was not announced.

Born in Belfast, Fraser was serving with the Royal Army Medical Corps in West Africa in 1942 when was sent to Algiers to take charge of a research team testing a new drug, penicillin. He carried out his research in a hospital but soon took it to the battlefield where the drug could be tested as soon as casualties occurred.

Fraser followed British troops ashore on the invasion of Sicily's beaches and operated aboard a ship continuously for 48 hours, saving many lives. He served until 1946, when he returned to Belfast.

He served as a senior consulting surgeon at the Royal Victoria Hospital, Belfast, and the Royal Belfast Hospital for Sick Children.

He was the first chairman of the Police Authority in Northern Ireland and was a member of the advisory council of the Ulster Defense Regiment, a locally recruited army unit now incorporated into the Royal Irish Regiment.

Fraser was knighted in 1963. His memoirs, ``Blood, Sweat and Cheers'' were published in 1989.

He is survived by a son and a daughter. A private funeral service was planned.
