What are the stages of grief? A search of the internet will turn up articles on 4 stages, 5 stages and even 7 stages of grief. The concept of stages has evolved from the “5 stages of dying” popularized by Dr. Elisabeth Kübler-Ross in her book, On Death and Dying, originally published in 1969. According to Dr. Kübler-Ross, the stages that a dying person goes through are: Denial and Isolation — initially the person denies that the situation exists, “It cannot possibly be,” and may withdraw and isolate himself from others.
