Robert M. Crocker, 61, secretary-treasurer of The Newspaper Guild, died of canner yesterday at his home in Silver Spring.

He was state capitol correspondent for the Associated Press in Augusta, Maine, when he was elected to the Guild international office in 1969.

Mr. Crocker was born in Auburn, Maine. He was a graduate of Bates College in Lewiston, where he started as a reporter for the Lewiston Evening Journal in 1939.

He joined the Worcester, Mass., Evening Gazette in 1941, and was the first president of the old Worcester Newspaper Guild.

In 1947, Mr. Crocker became an AP correspondent. He was president of the Wire Service Guild, Local 222, from 1963 to 1965, and from 1967 to 1968.

He was a former president of the Maine State House Newsmen's Association.

He is survived by his wife, Dorothy E., of the home in Silver Spring; a son, Stephen A., of North Whitefield, Maine; a daughter, Janet C. Rohman, of Gorham, Maine, and three grandchildren.

The family suggests that expressions of sympathy be in the form of contributions to the Irving Leuchter Memorial Scholarship Fund of The Newspaper Guild or the Bates College Alumni Fund in Lewiston. CAPTION: Picture, ROBERT M. CROCKER
