Logan D. Leathers, 54, a painters' union official who was active in community and church affairs, died Thursday at his Oxon Hill home following a heart attack.

He had been director of the apprentice program and executive secretary of the joint trade board for Painters District Council No. 51 since August of this year.

Prior to that, he worked as a foreman for the Clifton D. Mayhew Co., an Arlington painting firm, for 24 years.

Mr. Leathers was active in union local No. 1773 in Montgomery County for more than 25 years, and was recording secretary for more than 10 years.

He helped form the Fort Washington Boys and Girls Club and volunteered his services as football and basketball coach.

Mr. Leathers was a member of St. Theodore Greek Orthodox Church in Brandywine. He had been active in a number of church activities and had helped build protions of the church, including the cross at its front.

He is survived by his wife, Lorraine, two daughters, Carleen and Jill, and a son, Logan D. Jr., all of the home; two other daughters, Virginia K. Herring, of Ocean Springs, Miss., and Margaret E. Cochran, of Jacksonville, Fla.; a brother, James, of Durham, N.C.; three sisters, Carleen Burk, of Arlington, Virginia Collins, of Covington, Ky., and Katherine Lassiter, of Orlando, Fla.; and three grandchildren.

The family suggests that expressions of sympathy be in the form of contributions to the St. Theodore Greek Orthodox Church.
