After this, Klemperer's seemingly resurgent career received another severe set-back. At Montreal airport later in 1951 he slipped on ice and fell, breaking his hip. He was hospitalised for eight months. Then for a year he and his family were, as he put it, virtually prisoners in the US because of obstacles to leaving the country, following new legislation. With the help of an accomplished lawyer, he secured temporary six-month passports in 1954, and moved with his wife and daughter to Switzerland. He settled in Zürich, and obtained German citizenship and right of residency in Switzerland.
