In the early 1970s she had a studio in Florence where she associated with some of the key figures in the Situationist International,[1] including philosopher and filmmaker Guy Debord, the writer Gianfranco Sanguinetti and, later, the novelist and critic Michèle Bernstein.

[7] She contributed a memoir to a 2010 Paris exhibition catalogue of the artist and psychogeographer, and sometime Situationist, Ralph Rumney, whom she had befriended in the latter years of his life;[1] and her published reviews include an assessment of Claudia Herstatt's Women Gallerists for Tate Etc.
