Radziwiłł was one of the organisers of the Sikorski Historical Institute in London and founder of St. Anne's Church at Fawley Court, the site of Divine Mercy College, a school for boys of Polish origin, set up by the Marian Fathers in 1953 near Henley-on-Thames, England. He died on 27 July 1976, in London, six days after his 62nd birthday. His body was interred in the crypt of St Anne's Church at Fawley Court. Title
According to Debrett's, although known as Prince Radziwiłł in Britain, on becoming a British subject and in keeping with standard practice, Radziwiłł strictly needed permission from Queen Elizabeth II to use his princely title. The Radziwiłł family held the title Prince of the Holy Roman Empire since the early 16th century. However, noble titles were abolished in Poland and Austria. Ancestry
