Gehrdt Hinrich Bornebusch (15 April 1925 Ordrup – 10 November 2011 Humlebæk) was a Danish architect. He became a bricklayer in 1947, graduated from the Technical Society School in 1947 and graduated as an architect from the School of Architecture of the Academy of Fine Arts in 1950. Three years later he won the Academy’s gold medal. In 1956 he settled with Max Brüel and Jørgen Selchau. The best known project of this period is the Herlev Hospital (1965-1976), one of the major projects of its time in Denmark. However, the partnership ended in 1970 and 1985 respectively, after which Gehrdt Bornebusch continued with his own studio in Copenhagen.
He received the Wood Prize in 1966, the Eckersberg Medal in 1973 and the Concrete Prize in 1982. As inspector of royal buildings in the period 1982-1995, he was also the principal in charge of several restoration tasks, including Christiansborg Castle in 1986-1996, the National Museum in 1987-1996 and Brumleby in 1991-1996.
Bornebusch died in 2011 and was buried in Humlebæk Church.
