His family is a manufacturer and merchant of various goods, such as umbrellas, whips and swords. In 1851, his father disappeared in Brazil. Therefore, Mr Bourgeois, his maternal grandfather, make Prins an apprentice in his workshop. As he is passionate about sculpture, his mother suggested him to enrol an art class. He then enrolled in a school of art in 1861. His mother died in the same year.

In 1874, Prins participated in the creation of the Society of Painters, Sculptors and Engravers and decided to move to Namur with his wife. Before leaving, he sent twelve of his paintings to his childhood friend, the sculptor Émile Philippe Scailliet, so that he can hand the paintings to Alfred Sisley, who must deposit them at the workshop of Nadar for their first exhibition, which took place from 15 April 1874 to 15 May 1874. The couple later returned to Paris in 1875. In 1876, Pierre Prins restores ancient ivories for the Louvre Museum, and went to paint in the countryside on the side of Bas-Meudon, at Île Seguin. His wife, Fanny Claus-Prins, passed away in 1877, at the age of 31.
