Diego Giacometti, born in 1902, was at once the brother, the practitioner, the model and the confident of Alberto Giacometti. He became a reference in Decorative Arts as “artisan meublie”, which until then has been little explored by sculptors. In the 19th century, only Fremiet and Barye had left a coherent set of candelabras and lightings. With the help of Diego, Alberto produced in the 1930’s, for the interior designer Jean Michel Franck, the decorative objects we know :  lamps, floor lamps, bas reliefs and bouquets, etc.

It is from the end of this decade, in 1938 it is said, that Diego began to create his own decorative objects; these, in very small numbers, first because of all of the proximity and turbulence of the War, then the fact that after he dedicated himself totally to the practice for his elder whose notoriety became universal after 1947. This discreet and reserved man always refused to sign his own works before Alberto's death in 1966. Diego died a few years after the opening of the Picasso Museum for which he provided an impressive number of masterpieces which have proved to be in perfect harmony with the architecture of the museum.
