Egon, Prinz von Fürstenberg was a socialite, banker, fashion and interior designer, and a member of the former German princely family of Fürstenberg.
In 1969, he married fashion designer Diane Halfin, with whom he had two children, Alexandre Egon (born 25 January 1970) and Tatiana Desirée (born 16 February 1971). The couple separated in 1973 and divorced in 1983. The same year, he married Lynn Marshall (born c. 1950), an American from Mississippi who was the co-owner of a flower shop; the couple remained childless. Between his marriages, Egon also had a male partner; he was frank about his bisexuality and the openness of his first marriage.
Fürstenberg wrote two books on fashion and interior design (The Power Look, 1978, and The Power Look at Home: Decorating for Men, 1980), as well as opening an interior design firm. He died in Rome on 11 June 2004 of liver cancer deriving from an earlier hepatitis C infection. He was survived by his children and both wives.
