The combination of his brother Dieter at the age of nine having a fight with a playground bully wearing a Hitler Youth uniform and the increasing discrimination against Jews convinced their parents to send Klaus and Dieter to Craigend Park boarding school in Edinburgh. Upon arrival Klaus anglicised his name to Kenneth and eventually Ken while his brother Dieter changed his to Denis. Their oldest brother Peter was at the time studying law at the University of Clermont-Ferrand in France and decided to move to England and complete his studies there.
