(1946 - 1949) (divorced)
After the war, Carroll stayed in Europe where she conducted a radio program fostering French-American friendship and helped in the rehabilitation of concentration camp victims, during which she met her future third husband, French producer Henri Lavorel. In late 1946, she went briefly to Switzerland to film a British soap opera, High Fury (aka White Cradle Inn).
Upon her return to Paris she and Lavorel formed a production company and made several two-reel documentaries to “promote better understanding among the peoples of the world”; one, “Childrens’ Republic”, was shown at the Cannes Film Festival. Filmed in a small orphanage in the town of Sèvres, just southwest of Paris, it focused attention on the devastation of children’s lives in Europe caused by war. Strongly shown in Canada, it became a prime source of funds for the manufacture of artificial limbs for wounded children.
In 1947 Carroll returned to the U.S. together with Lavorel. Their intention was for her to resume her acting career, which would fund their production company, but they soon separated. Appearing in three more films until 1949, and debuting on Broadway in 1948, Carroll then mostly retired from acting, although she would occasionally show up on television and radio until the mid-1960s.
