Harry L. Slye, 69, a retired executive of the Continental Baking Co. and a community leader in Silver Spring-Takoma Park, died of cancer Thursday at the Washington Adventist Hospital in Takoma Park.

Mr. Slye started working for Continental more than 45 years ago, loading bread onto trucks. He later became sales manager and then general manager of County Fair Bakery, a division of Continental. When he retired in 1972, he was the company's eastern regional products manager.

A lifelong area resident, Mr. Slye was born in Washington and lived in Silver Spring. He graduated from old Business High School and Benjamin Franklin University in Washington.

Mr. Slye was instrumental in establishing HELP Inc. of Silver Spring, a multichurch emergency aid service, and served as its director for six years. He also was chairman of the TESS (Takoma East-Silver Spring) Community Service Center.

He helped found the St. Paul Day Care Center in Silver Spring and served for many years as treasurer of Woodside United Methodist Church in Silver Spring, of which he was a member for more than 40 years.

A 32nd degree Mason, Mr. Slye was a member of Silver Spring Lodge No.

215 and of the Scottish Rite.

Survivors include his wife, Janet L., of Silver Spring; two daughters, Sandra Ehlert of Emmitsburg, Md., and Judity Lilga of Gaithersburg; three sons, the Rev. Harry L., of Houston, Air Force Lt. Col. Richard H., of Germany, and Jack J., of Sharpsburg, Md.; three stepchildren, Debbie Dillon of Virginia, and Craig A. and Ronald A. Zimmerman, both of Silver Spring; a sister, Nellie Schweitzer of Adamstown, Md.; a brother, Freeman D., of Takoma Park, and 10 grandchildren.

The family suggests that expressions of sympathy be in the form of contributions to Woodside United Methodist Church Memorial Fund, to HELP Inc. of Silver Spring, or to the American Cancer Society.
