The Frances Tustin Memorial Trust was established in Los Angeles, California in 1995, dedicated to the teaching, expansion and extension of Frances Tustin’s seminal work on the understanding and treatment of autistic spectrum disorders in children, adolescents and adults, as well as the treatment of autistic states and defenses in individuals of all ages. To reach this goal, each year the Trust grants The Frances Tustin Memorial Prize and Lecture, now co-sponsored by The Program of Psychotherapy, Sackler Faculty of Medicine, Tel Aviv University. Each year the Trust awards a cash prize of $1,000 to the author of an outstanding clinical paper on the psychoanalytic treatment of primitive mental states in general and autistic states and defenses, in particular, in children, adolescents or adults. The prize-winning author is invited to present his/her paper at The Frances Tustin Memorial Lectureship day held each year in Tel-Aviv, Israel in October/November to commemorate the anniversary of Frances Tustin’s death on November 10, 1994.
