of their careers. Their first collaboration was Stromboli terra di Dio (1950) (in the island of Stromboli, and its volcano quite conveniently erupted during filming). This affair caused a great scandal in some countries (Bergman and Rossellini were married to other people); the scandal intensified when Bergman became pregnant with Renato Roberto Ranaldo Giusto Giuseppe ("Robin") Rossellini. Rossellini and Bergman had two more children, Isabella Rossellini (actress & model) and her twin, Ingrid Isotta. Europa '51 (1952), Siamo Donne (1953), Journey to Italy (1954), La paura (1954) and Giovanna d'Arco al rogo (1954) were the other films on which they worked together. In 1957, Jawaharlal Nehru, the prime minister of India at the time, invited him to India to make the documentary India and put some life into the floundering Indian Films Division. Though married to Bergman, he had an affair with Sonali Senroy Dasgupta, a screenwriter, herself married to local filmmaker Harisadhan Dasgupta, who was helping develop vignettes for the film. Given the climate of the 1950s, this led to a huge scandal in India as well as in Hollywood. Nehru had to ask Rossellini to leave. Soon after, Bergman and Rossellini separated. In 1971, Rice University in Houston, Texas, invited Rossellini to help establish a Media Center, where in 1970 he had begun planning a film on science with Rice professor Donald D. Clayton. They worked daily for two weeks in Rome in summer 1970, but financing was insufficient for filming to begin. In 1973, he was invited to teach at Yale University in New Haven, Connecticut, where he taught a one-semester course titled "The Essential Image." Rossellini's final project was the documentary Beaubourg, filmed in 1977 and first premiered in 1983. Personal life In 1934, Rossellini married Assia Noris, a Russian actress who worked in Italian films; the marriage was annulled in 1936. On 26 September 1936, he married Marcella De Marchis (17 January 1916, Rome – 25 February 2009, Sarteano), a costume designer with whom he collaborated even after their marriage was over. De Marchis and Rossellini had two sons: Marco Romano (born 3 July 1937 and died of appendicitis in 1946), and Renzo (born 24 August 1941). Rossellini and De Marchis divorced in 1950. While filming Stromboli, Rossellini had an affair with Ingrid Bergman (who was at the time married to Petter Lindström) in 1949. In the same month the film was released, Bergman gave
