“Marking Infinity”, Lee Ufan’s recent retrospective exhibition at the Guggenheim charts the artist’s creation of a visual, conceptual, and theoretical language that has radically expanded the possibilities for sculpture and painting over the past forty years. Deeply versed in modern philosophy, Lee is also an influential writer and is recognized as the key theorist of Mono-ha, an anti-formalist, materials-based art movement that developed in Tokyo in the late 1960s. Active internationally over the last four decades, Lee is acclaimed for an innovative body of Post-Minimalist work that promotes process and the experiential engagement of viewer and site.
