This is Joan Riviere’s last published contribution, and it is fitting that, as such, it is a tribute to the founder of Psycho-Analysis, Sigmund Freud, on the occasion of the centenary of his birth, 6 May 1956. It was written at the request of the Public Lectures Committee of the British Psycho-Analytical Society, and it is a sympathetic appreciation of Freud as a creative scientist, who, like Joan Riviere herself, found expression for his creativity in his writings. And like her, too, he did not need to impress himself on others to win their approval and support for his views. Yet, as she points out, he was able to write in such a way that his readers could see themselves as allied to his ideas, and involved in understanding the truths that he was seeking to find, as well as those he was searching to create—‘new living truth—the scientist and the artist in one’.
