Elisabeth Kübler-Ross was a Swiss-American psychiatrist renowned for her groundbreaking work in the field of thanatology and her development of the Kübler-Ross model, also known as the Five Stages of Grief. Born on July 8, 1926, in Zurich, Switzerland, she emigrated to the United States where she became a pioneering voice in the hospice and palliative care movements. Her seminal book, "On Death and Dying" (1969), transformed how society views terminal illness and end-of-life care. An advocate for compassionate treatment of the dying, she dedicated her life to improving understanding of death and grief, leaving an enduring legacy.
