Lamarr became a naturalized citizen of the United States at age 38 on April 10, 1953. Her autobiography, "Ecstasy and Me", was published in 1966. In a 1969 interview on "The Merv Griffin Show", she said that she did not write it and claimed that much was fictional. Lamarr sued the publisher in 1966 to halt publication, saying that many details were fabricated by its ghost writer, Leo Guild. She lost the suit. In 1967, Lamarr was sued by Gene Ringgold, who asserted that the book plagiarized material from an article he had written in 1965 for "Screen Facts" magazine.
