Alexander Serebriakoff (d. 1994), born in Russia into a family of artists, settled in Paris and met Beistegui in 1941, when he was asked to paint rooms in the château de Groussay. Serebriakoff was not only a chronicler for Beistegui by painting interiors, he also helped realize concepts for parties and projects in the park at Groussay. Serebriakoff designed numerous architectural buildings for him, some of which were realized by Emilio Terry and Michel de Bross as full-scale buildings in the park.
