Reporting from Chicago — Mahalia Jackson, whose soulful renditions of gospel music thrilled fans the world over, including Presidents and European royalty, died Thursday at Little Company of Mary Hospital in a south Chicago suburb. She was 60. A hospital spokesman said heart disease was the immediate cause of her death. Miss Jackson, who had been in declining health for months, entered the hospital Jan. 19 suffering from an intestinal condition. She had been hospitalized intermittently since 1964 for heart trouble, and returned to the United States from an appearance in Germany last October suffering from a heart ailment. She had made fewer public appearances the last five years, primarily because of declining health.
