Sophie Calle is a French writer, photographer, installation artist, and conceptual artist. Calle's work is distinguished by its use of arbitrary sets of constraints, and evokes the French literary movement known as Oulipo. Her work frequently depicts human vulnerability, and examines identity and intimacy. She is recognized for her detective-like tendency to follow strangers and investigate their private lives. Her photographic work often includes panels of text of her own writing.

Conceptual art, also referred to as conceptualism, is art in which the concept(s) or idea(s) involved in the work are prioritized equally to or more than traditional aesthetic, technical, and material concerns. Some works of conceptual art may be constructed by anyone simply by following a set of written instructions. This method was fundamental to American artist Sol LeWitt's definition of conceptual art, one of the first to appear in print:In conceptual art the idea or concept is the most important aspect of the work. When an artist uses a conceptual form of art, it means that all of the planning and decisions are made beforehand and the execution is a perfunctory affair. The idea becomes a machine that makes the art.
