The Rev. Dr. John McLaughin McNeill, 76, a former world evangelist, radio pastor and musician-composer, died Thursday at Alexandria Hospital. He had suffered from a heart condition.

He was called to Washington in 1941 to be pastor of what was then known as the Nonsectarian Tabernacle. It became the National Tabernacle and he remained its pastor until 1944.

He also was heard on such radio broadcasts here as "Church of the Air," Chancel Steps" and "The Back Home Hour."

After he left the Tabernacle, which is now Forcey Memorial Church in White Oak, Md., Dr. McNeill traveled throughout this country and around the world as an evangelist. His home base remained here.

An accomplished organist and pianist, he continued to compose church music in later years.

Born in Gasglow, Scotland, the son of an evangelist, Dr. McNeill attended universities and colleges in Europe and America. His numerous degrees included doctors of divinity, doctor of theology, doctor of laws, doctor of literature and doctor of music.

Dr. McNeill was ordained a Presbyterian minister in Gasgow. During World War I, he served with the British Merchant Marine service. He came to this country in 1927, and was based in Chicago before coming here.

He is survived by his wife, Chrissie R., of the home in Alexandria; a daughter, Mrs. Robert H. Milan, of College Park; one brother, three sisters and two grandchildren.
