Peter Horn was born in 1936 in Kiel, Germany. Instructed by his mother, he made his first attempts at weaving while still a pupil. After graduation with the ‚Abitur‘, he enrolled at the Christian-Albrechts-University Kiel to train to be a teacher for English and Geography. During 1958 he went to the Muthesius-Schule, Kiel‘s art and design college, as a guest reader on the preliminary course. In 1959-60 he studied at Queen‘s College at the University of London. It was on his return from England that Peter Horn turned intensively to drawing, painting and, most of all, tapestry weaving.
After qualifying as a teacher in 1962, he took up the post of supply teacher at a secondary school in Neumünster. He was asked to take over all art lessons, which suited his interests very much. He stayed at the school until 1970, when he was invited to move to the Kiel School of
Pedagogics (Pädagogische Hochschule), after he had obtained a teaching degree in art, as his third subject, in 1969.
At the Pädagogische Hochschule he taught the subjects of textile crafts and, later, also art, on the teacher training course, passing on his skills and experience in several artistic disciplines, but especially of tapestry, to many students. His studio work took the place of a second career, parallel to his day job, resulting in a combination which, due to many overlaps within the artistic disciplines, made for intensive and satisfying work.
