At a very young age, he showed himself gifted in drawing. His art studies include; l'école d’arts, Bernard Palissy, and l'Ecole Nationale Supérieure des Beaux-Arts.

He was awarded the first Rome Grand Prix in 1927 for a high relief presenting L'invention of the Cornucopia. The marble counterpart of this work is located at the Museum at St-Siméon in California.

His artistic life knows three eras; the first one is devoted to the reconstruction of many churches and town halls devastated by the First World War in the north of France. He contributed to much of the decoration by casting in cement.

His second period, produced many busts, official orders and commemorative monuments in stone. In Paris a large bust of Pierre Curie intended for the Palace of Discovery, the statue of Claude Bernard in front of the College of France, Queen Astrid at the University City, The Woman to at the Bath for a park, and the biggest casting at the time for the l'Exposition Internationale of 1937. In the provinces, he sculptured monuments of Raymond Poincaré, of Franklin D. Roosevelt, the Cesnay and one of the "resistant ones" of the southwest for Neuvic, then a stèle to the glory of the "liberating ones" at Amboise, and many more.

Later, Electricité de France commissioned him between 1956 and 1973 the important task of decorating the hydraulic and nuclear power stations of France.

Concurrently to these great pieces of monumental sculpture, Couvègnes designed awards and orders for the l'Hôtel des Monnaies (Paris Mint), including medals of President Poincaré, painter Kandinski, and the Basketball Medal in 1976.

He died in 1985 in his city of Boulogne; where he had created the l'école of the Arts and taught sculpture.
