DIED. Bernard J.F. Lonergan, 79, Jesuit philosopher and theologian whose championship of rigorous intellectual inquiry as a means of revivifying faith placed him among the foremost Christian thinkers of the 20th century; in Pickering, Ont. A demanding and temperamental teacher, the priest was the author of two densely reasoned, seminal texts: Insight: A Study of Human Understanding (1957) and Method in Theology (1972).

DIED. Sylvan N. Goldman, 86, inventor of the shopping cart and multimillionaire philanthropist whose fortune was estimated last year by Forbes magazine to be $200 million; in Oklahoma City. Supermarket Owner Goldman built the first shopping-cart prototype in the mid-1930s using a folding chair as a model. The idea, which he patented and eventually marketed, came to him while he watched women using then standard market baskets. Said he: "They had a tendency to stop shopping when the baskets became too full or too heavy."

One of Germany's military elite, Speidel became disgusted with Hitler's conduct of the war and joined the unsuccessful bomb plot to kill the Nazi dictator at Hitler's East Prussia headquarters. Remaining silent under interrogation, Speidel survived the subsequent Gestapo inquisition. When West Germany's army was finally rebuilt in the mid-1950s, he was called to help and became one of NATO's most respected commanders.
