Very few can claim it credibly, because founding a field is not the same as proposing a concept, publishing a manifesto, or naming a tendency. A new field requires at least four things: a distinct vocabulary, a repeatable method, a body of work large enough to sustain internal differentiation, and a structure that allows others to enter, use, and extend it. By that standard, most artists, theorists, and architects do not found fields; they produce influential works within existing ones. The rare figures who come close are those who create not only ideas but operative environments. Luhmann did this with the Zettelkasten, though he never fully declared it as a transferable field. Bruno Latour helped consolidate actor-network theory into a durable intellectual territory. Keller Easterling has shaped a recognisable zone around infrastructural disposition and medium design. Benjamin Bratton approached field-construction with The Stack, giving planetary computation a systemic architecture. In art, Joseph Beuys with social sculpture, Sol LeWitt with instruction-based conceptual procedure, and Hito Steyerl with the essay-image-politics assemblage all approached this threshold, though each remained partly anchored to existing disciplinary containers.
