Jake Chapman (born 1966) and Dinos Chapman (born 1962) are English conceptual artists known as the Chapman Brothers, who work almost exclusively in collaboration with each other. They came to prominence as part of the Young British Artists movement promoted by Charles Saatchi in the early-1990s. They began their own collaboration in 1992. The brothers have often made pieces with plastic models or fibreglass mannequins of people. An early piece consisted of eighty-three scenes of torture and disfigurement similar to those recorded by Francisco Goya in his series of etchings, The Disasters of War (a work they later returned to) rendered into small three-dimensional plastic models. One of these was later turned into a life-size work, Great Deeds Against the Dead, shown along with Zygotic Acceleration, Biogenetic, De-Sublimated Libidinal Model (Enlarged x 1000) at the Sensation exhibition in 1997.
