Ferdinand Carre (1824-1900): Born at Somme, France, Ferdinand Carre was a versatile engineer of great intellect. He was interested in variety of subjects. From 1857 he studied refrigeration using ethyl ether and ammonia and was granted more than 50 patents in the area of refrigeration. The patent of 1859 describes a continuous vapour absorption refrigeration system using ammonia as refrigerant and water as absorbent. In 1876 he equipped the ship “Paraguay” with an absorption refrigeration system. The ship made an intercontinental trip with frozen meat on-board. Carre was a quiet man, with little interest in industrial use of his inventions.
