Studies in England, then internment[edit]

He was studying at Cambridge, living incognito under the name of Count von Lingen, when war broke out in September 1939. He was arrested and interned in May 1940. He was held in England for several months, then sent to internment camps near Quebec City and soon afterwards, Farnham, Quebec. In both camps, he was elected camp leader by fellow inmates.[5]

British naturalisation in 1947[edit]

He renounced his German citizenship in 1947[2] and hence relinquished his place in the line of succession to the former German throne.[2] Being a descendant of Sophia of Hanover, and having rights under the Act of Settlement 1701, as amended by the Sophia Naturalisation Act 1705, he was naturalised as a British citizen in October 1947 under the name Mr. Friedrich von Preussen (having also been known during residence in the UK as "George Mansfield").[2] This naturalization was controversial to some, and his status and a subsequent claim for compensation was debated in Parliament and the law courts until 1961.[1] In the period 1917-32, it was settled that a person who had a foreign title would normally undertake to relinquish it before he/she could receive a certificate of British naturalization, and no exception was made in the case of Mr. Friedrich von Preussen.[6]


He was the owner of Reinhartshausen Castle at Erbach, Germany. While staying there in 1966, he went missing and was found two weeks later, having drowned in the Rhine, whether suicidally or accidentally could not be determined.[2]
