The Quay Brothers reside and work in England, having moved there in 1969 to study at the Royal College of Art, London after studying illustration at the Philadelphia College of Art, now the University of the Arts in Philadelphia. In England they made their first short films, which no longer exist after the only print was irreparably damaged. They spent some time in the Netherlands in the 1970s and then returned to England where they teamed up with another Royal College student, Keith Griffiths, who produced all of their films. The trio formed Koninck Studios in 1980, which is currently based in Southwark, south London.
