As a student, Kuehn produced a sculpture for the 1963 Yam Festival organized by George Brecht and Robert Watts in New Brusnswick, New Jersey and in 1964 he choreographed a performance at the Hardware Poets Playhouse in New York.
I posit geometry as the expression of the ideal, the pinnacle of rational thinking, and a source of authority..."[10] Kuehn's work was included in the groundbreaking exhibition Eccentric Abstraction curated by Lucy Lippard in 1966 at the Fischbach Gallery in New York.
Considered the first Postminimal art exhibition, Eccentric Abstraction brought together artists including Eva Hesse, Keith Sonnier, and Bruce Nauman who were subverting the rigid hard-edge Minimalism that was dominant at the time.
[11][12] Kuehn's work was also included in the seminal exhibition Live In Your Head: When Attitudes Become Form curated by Harald Szeemann in 1969 at the Kunsthalle Bern, which traveled to Museum Haus Lange, Krefeld and Institute of Contemporary Arts, London, and was re-staged in 2013 at the Fondazione Prada, Milan.
Kuehn's focus is a concept of art that enables him to explore questions of geometry and form while also reflecting on and sculpturally negotiating aspects of expression, human experience, and self-perception.
His aesthetic approach is based on a certain idea about rationality- not in a formal or compositional sense but in a manner analogous to human and interpersonal experiences - which he understands as the relationship of objects to one another and their potential means of expression or attitudes.
