Pina studied with Rodin in Paris from 1909 to 1910 and like many other sculptors of this time, was deeply influenced by the "Master"  In the years preceding the First World War, he exhibited at the Salon des Artistes Français, the Tuileries and the Salon d'Automne --where he was a member of the Jury from 1911. During this time, he socialized in the artistic circles of Montparnasse . He was famously attacked by Modigliani at a banquet given for Braque during the war. The attack by Modigliani was brought on by Pina's clandestine relationship with Beatrice Hastings, with whom Modigliani was living at the time.
After the war, Pina began exhibiting at the Salon des Indépendants. He achieved commercial success in his lifetime with the Valsuani foundry --who cast many of his figurative models and busts in bronze.

The present unique white marble sculpture of Adam was created as the male figure in a pair of male and female marble sculptures he titled "Reveil a la nature"- (The awakening of nature).
