Louis-Ellies Dupin, born 17 June, 1657; died 6 June, 1719. He wrote at great length upon the Fathers, many of whose works he edited with commentaries. Some of his statements involved him in disputes with Dom. Petit-Didier and later with Bossuet. Dupin is an extremely prolific author, but several of his propsitions were regarded as suspect in orthodoxy.
