Martin L. Beard, 58, a Maryland builder and businessman, died Monday at his home in Silver Spring. He had undergone heart surgery last March.

He came here shortly after World War II as a claims manager in the Washington offices of the Glens Falls Insurance Co. of New York.

Mr. Beard opened a service station in Simpsonville, Md., in the late 1940s and operated it until the 1950s, when he established a building company. He was involved in the construction of several developments in Montgomery and Howard Counties, including Arrowhead in Howard County.

More recently, Mr. Beard was in the glass installation business, first as a manager with area firms and then in his own business in Silver Spring.

Born in Queens County, N.Y., he attended Gettysburg College. During World War II, he served with the Army in the South Pacific.

He is survived by his wife, Helen L. Beard, of the home in Silver Spring; four daughters, Carol Brown, of Woodbine, Md.; Suzanne Klein, of Lancaster, Pa.; Kathleen Beard, of Aspen, Colo., and Paula Lewellen, of Silver Spring; three sisters, Ethel Biehl, of Owings Mills, Md.; Catherine Griffin, of Denver, and Elinore Wolfe, of Silver Spring; and three grandchildren.
