This situation is not satisfactory and does not meet the needs. Auzoux chooses the technique of papier mâché to build life size or enlarged models of human organs, so enabling an easy simulation of joints and a disassembly.
In 1825, the Académie Royale de Médecine authorizes their edition. The brilliant inventor is 28 years old. He establishes in his village a factory which will exercise this activity until the early 2000s and includes a complete human écorché from his first catalog.
The interest of anatomists for animals dates back to antiquity. In Rome, Galen dissected macaque monkeys to define the treatment of human diseases. The work of Auzoux undeniably influenced Darwin.
The new zoological wonder is the gorilla whose existence was confirmed in 1847. Its name used 2,400 years earlier by Hanno meant hairy woman in the language of the explorer and the animal had remained a myth like unicorns or mermaids as long as it was not seen again.
In 1863 Auzoux convinces the Emperor Napoléon III of the advantage to study this creature so similar to humans. A specimen is sent from Africa and Auzoux realizes its public dissection in the amphitheater of the Ecole de Médecine. He discovered during this inspection that the gorilla has the same gripping thumbs as man.
In the same year, the life size gorilla is entered in Auzoux's catalog. It is constituted of 1193 elements. The right hand is raised to a branch for an overall height of 2.17 m.
On September 10 in London, Christie's sells the prototype of the Auzoux gorilla, lot 22 estimated £ 80K, accompanied by an autograph manuscript of 65 pages describing the removable pieces. A copy as an écorché was sold for € 13K before fees by Christophe Joron-Derem on December 16, 2013.
