Maurizio Montalbini Dies

Italian sociologist Maurizio Montalbini, 56, who spent months dwelling in caves to study how the mind and body cope with complete isolation, died of a heart attack Sept. 19 in a mountain hamlet near the central Italian town of Macerata, said Guido Galvagno, a longtime colleague. Galvagno said the death did not appear connected to Mr. Montalbini's record-breaking cave stays.

Mr. Montalbini, who had no children, is survived by his wife, Galvagno said.

Rest In Peace, Maurizio.
