In the 1990s, Louise Bourgeois continued to explore complex themes of memory, body, and emotion through her distinctive sculptures and installations. This decade was marked by significant contributions to her body of work, including the continuation and expansion of her famous "Cells" series, initiated in the late 1980s. The "Cells" encapsulate a range of emotions and narratives, often incorporating architectural elements like doors and wire mesh, alongside found objects and sculptural components, to create immersive environments that engage with notions of psychological and physical space​ (Art21)​. One notable work from this period, "Cell (Choisy)" (1990-1993), exemplifies Bourgeois' mastery in using diverse materials such as marble, metal, and glass. This piece, like others in the "Cells" series, offers a deep dive into Bourgeois' introspective and often autobiographical art, inviting viewers into a space that feels both intensely personal and universally resonant​ (Artsy)​. The 1990s also saw Bourgeois delve into other forms of expression within her sculptural practice. Works like "The Nest" (1994) and "Spiral" (1994) showcase her ability to manipulate materials and forms to evoke a sense of entanglement and introspection. "The Nest" is a large-scale steel sculpture that, true to its name, suggests a complex, protective structure. Meanwhile, "Spiral" combines watercolor, ink, and colored pencil on paper to explore the motif of the spiral, which for Bourgeois symbolized continuity and the passage of time, themes that recur throughout her oeuvre​ (Art21)​. Through these works and others during the decade, Bourgeois continued to push the boundaries of contemporary art, employing her unique visual language to explore the depths of human emotion and experience. Her work from the 1990s not only contributed to the legacy she would leave as one of the 20th century's most influential artists but also underscored her role in the development of feminist art and installation art as vital contemporary art forms.
