© Max Mbakop Princess Marilyn Douala Manga Bell was born in Cameroon in 1957, into the royal family of the Bell lineage. She has a post-graduate degree in Development Economics obtained in Paris.

She directs the contemporary art centre doual'art, founded in 1991 with the art historian Didier Schaub, whose concern is to accompany the new urban identities at the same time as the construction of a contemporary citizenship through artistic action in the urban social space, for popular education and collective memory.

With her late husband, Didier Schaub who was an art historian, and a group of friends, she created the association doual'art in 1991, a contemporary art centre that defines itself as a research laboratory "Ars & Urbis", on art and the urban. Its main concern is to accompany new urban identities while participating in the construction of a contemporary citizenship through artistic action in the urban social space, and for popular education and collective memory.

The main tool of doual'art is the international triennial of public art SUD - Salon Urbain de Douala - which, since the first edition in 2007, has offered more than 80 artworks and artistic events in the city of Douala.

Since 2014, she has been working on memorial projects concerning German colonial history in Cameroon.
