Princess Catherine Radziwill (30 March 1858 - 12 May 1941) was a Polish princess from a famous Polish-Lithuanian aristocratic family. She was possibly the author of a book gossiping about the German Emperor William II and Berlin society in 1884 under the pseudonym Paul Vasili. She stalked the English-born South African politician Cecil Rhodes. After she asked him to marry her and he refused, she sought revenge by forging his name on a promissory te. Radziwill was convicted of forging Rhodes' signature and spent time in a South African jail. This account of a turbulent time in South Africa's history is made more interesting by the relationship of Catherine to Cecil Rhodes.
