Charles Percier was a neoclassical French architect, interior decorator and designer, who worked in a close partnership with Pierre François Léonard Fontaine, originally his friend from student days. For work undertaken from 1794 onward, trying to ascribe conceptions or details to one or other of them is fruitless; it is impossible to disentangle their cooperative efforts in this fashion. Together, Percier and Fontaine were inventors and major proponents of the rich, grand, consciously-archaeological versions of neoclassicism we recognise as Directoire style and Empire style.
Following Charles Percier's death in 1838, Fontaine designed a tomb in their characteristic style in the Pere Lachaise Cemetery. Percier and Fontaine had lived together as well as being colleagues. Fontaine married late in life and after his death in 1853 his body was placed in the same tomb according to his wishes.
