With no direct heirs, the couple decided to devote their fortune to causes driven by a humanist vision. On his deathbed in 1985, Pierre reiterates to his wife his desire to intelligently distribute their money and his desire to see his name live on. Andrée will honour her husband’s will by leaving it to his trusted men (the members of the foundation board) to create, during his lifetime, a foundation of the same name. Andrée died in Geneva in 2017. Pierre and Andrée Haas leave to posterity a legacy that the Foundation endeavours to make bear fruit, with the aim of sharing it according to the wishes of the deceased.
