Egon, Prinz von Fürstenberg (Eduard Egon Peter Paul Giovanni Prinz zu Fürstenberg; 29 June 1946 – 11 June 2004) 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. Family Eduard Egon Peter Paul Giovanni Prinz zu Fürstenberg, born 29 June 1946 in Lausanne, Switzerland, was the elder son of Prince Tassilo zu Fürstenberg (1903–1989) and his first wife, Clara Agnelli (1920-2016), elder sister of Fiat's chairman Gianni Agnelli. After Clara's departure, his father married Texas oil heiress Dr. Cecilie Amelia Hudson (née Blaffer). Fürstenberg's younger brother is Prince Sebastian zu Fürstenberg, and his sister is socialite and actress Princess Ira zu Fürstenberg. Biography Egon von Fürstenberg was born in Lausanne, Switzerland. He was baptized by the French nuncio Angelo Roncalli (later elected Pope John XXIII) and was brought up in great privilege in Venice, Italy. He earned a degree in economics from the University of Geneva, followed by an 14-month term on a peace mission in Burundi working as a teacher, and then two years as an investment banker in New York. While studying at a university, he met fellow student Diane Simone Michelle Halfin, a Belgian-born Jewish woman of Romanian-Greek descent and daughter of a Holocaust survivor. They married on 16 July 1969, at Montfort-l'Amaury, Yvelines, France. The new Princess Diane von Fürstenberg was pregnant, and Egon's father, who objected to his son marrying a Jew, boycotted the ceremony. His wife opened her fashion house in New York at Egon's urging, creating an eventually iconic wrap dress,
