earthquake. Many of López's friends from childhood and their families died in the event. Education López attended the Medical School at UNAM, Universidad Nacional Autónoma de México, with the idea of later training in Psychiatry and Psychoanalysis. As a medical student he developed strong relationships with the psychoanalytic group at UNAM, the psychiatrists at General Hospital of Mexico, and - through his father's Spanish connections - to the Hospital Español de México. These relationships would later support his efforts of integrating differing groups into the training program he developed at UNAM. López then graduated as a psychiatrist from the Medical College of Pennsylvania, and as a child and adolescent psychiatrist from the Eastern Pennsylvania Psychiatric Institute (EPPI). He studied Psychoanalysis and Child Psychoanalysis at the Institute of the Mexican Psychoanalytic Association. Psychiatric Practice López lived and practiced from 1972 to 2009 in a suburb of Mexico City. From 2009 to 2013 he practiced in Barcelona, Spain, and in New York from 2013 to 2017. During his last years, López helped organize the first program in child psychoanalytic training at IPTAR (The Institute For Psychoanalytic Training and Research), in New York City. Academic life López published more than 150 original articles and two books: "La Encrucijada de la Adolescencia ("The Crossroads of Adolescence") and "Ética en Psiquiatría, Psicoanálisis y Psicoterapia" ("Ethics in Psychiatry, Psychoanalysis, and Psychotherapy"). In 2018, the Manuel Isaías López Foundation published posthumously his book "Desarrollo de la Identidad y Nacionalismo Mexicanos: A Quinientos Años" ("The Development of Mexican Identity: A Psychological Perspective"). Mann de Dayán describes the "Sensory Oversaturation Syndrome" as López's main contribution to the psychodynamics of adolescence. According to this phenomenon, the adolescent manages to move away from his own narcissistic needs by overstimulating himself, as a first step before he projects his needs to outside sources. Death Manuel Isaías López died in New York City on November 29, 2017.
