Peter Wilker
(1st November 1922 - Bern, Switzerland: 3rd April 2002)
Peter Wilker, born in Vienna, Austria, was a Swiss amateur magician and author. He studied math and became a professor of mathematics at the University of Bern. He therefore was quite interested in mathematical principles and in particular magic squares. He was the editor of the Swiss magazine Hokus Pokus from 1976 until 1985, and he contributed regularly to other periodicals such as Abracadabra and Magische Welt. From 1986 to 1988 he published the periodical Magische Blätter. Together with Dietmar Buggisch he translated parts of The Discoverie of Witchcraft to German. In 1988 he moved to Cornwall England where he became a member of the Cornish Magic Society.
Peter Wilker collected his entire life jokes. His daughter Jessica Wilker published his best 100 jokes (in German) in the book Peters Witzbüchlein.
