Preben Juul Fabricius (1931–1984) was a Danish furniture designer who worked together with Jørgen Kastholm. Fabricius was trained as a cabinetmaker by Niels Vodder before attending the School for Interior Design where he studied under Finn Juhl. The pieces of furniture they produced during their seven-year period of cooperation from 1961 to 1968 were so distinctive that many are still produced today as classics. As a result of disagreements, the pair decided to terminate their cooperation in 1968.
