Andre's early work in wood may have been inspired by Brâncuși, but his conversations with Stella about space and form led him in a different direction. While sharing a studio with Stella, Andre developed a series of wooden "cut" sculptures[5] (such as Radial Arm Saw cut sculpture, 1959, and Maple Spindle Exercise, 1959). Stella is noted as having said to Andre (regarding hunks of wood removed from Andre's sculpture) "Carl, that's sculpture, too."[7]
From 1960-64 Andre worked as freight brakeman and conductor in New Jersey for the Pennsylvania Railroad. The experience with blue collar labor and the ordered nature of conducting freight trains would have a later influence on Andre's sculpture and artistic personality. For example, it was not uncommon for Andre to dress in overalls and a blue work shirt, even to the most formal occasions."[4]
During this period, Andre focused mainly on writing and there is little notable sculpture on record between 1960 and 1965. The poetry would resurface later, most notably in a book (finally published in 1980 by NYU press) called 12 Dialogues in which Andre and Frampton took turns responding to one another at a typewriter using mainly poetry and free-form essay-like texts.[5] Andre's concrete poetry has exhibited in the United States and Europe, a comprehensive collection of which is in the collection of the Stedelijk Museum in Amsterdam.[8]
In 1965 he had his first public exhibition of work in the Shape and Structure show curated by Henry Geldzahler at the Tibor de Nagy Gallery.[9]
Andre's controversial "Lever" was included in the seminal 1966 show at the Jewish Museum in New York entitled Primary Structures.
In 1969 Andre helped organize the Art Workers Coalition.
In 1970 he had a solo exhibition at the Solomon R. Guggenheim Museum, and has had solo exhibitions and participated in group shows in major museums, galleries, and kunsthalles throughout America and Europe.
In 1972, Britain's Tate Gallery acquired Andre's Equivalent VIII, an arrangement of fireplace bricks. The piece was exhibited several times without incident, but became the center of controversy in 1976 after being featured in an article in The Sunday Times and later being defaced with paint. The "Bricks controversy" became one of the most famous public debates in Britain about contemporary art.[10][11]
