From: Antoine de Baecque and Serge Toubiana, Truffaut, translated from the French by Catherine Temerson, Alfred A. Knopf: New York, NY (1999), page 160:
As soon as he arrived in New York, Truffaut made an acquaintance that would be crucial for his American career. Helen Scott was in charge of public relations at the French Film Office... In this capacity, she welcomed Truffaut at the airport upon his arrival in New York and served as his guide and interpreter. Cultivated, fluent in French, a great film enthusiast blessed with a good New York Jewish sense of humor, Scott had been active in the American Left, and later would be in the feminist movement. During the McCarthy period, she had been blacklisted for so-called anti-American activities along with many other wrtiers, screenwriters, left-wing film directors, and members of the American Communist party. With her thorough knowledge of the New York cultural scene and the press, Scott was an indispensable ally for Truffaut in the United States.de Baecque/Toubiana, page 198:
After this long series of interviews [with Alfred Hitchcock], Truffaut returned to Paris, where he immediatly felt nostalgic about the "week when I fulfilled an old dream--talking with Hitchcok to my heart's content about cinema." This California sojourn greatly contributed in drawing Helen Scott and Francois Truffaut closer together--not only because they had proved a good team but also because something of a misunderstanding arose, causing a greater complicitous bond between them. For Helen Scott, of course, was in love with Truffaut, while he saw her as a caring "Jewish mother," with a marvelous sense of humor, but not at all as a mistress.
