Dr. Yehuda Nir (1930-2014) was a highly-regarded psychiatrist with the Cornell University Medical Center and the Sloane Kettering Cancer Institute in New York City, where he specialized in trauma counseling of terminally ill children and their parents. Nir had many patients who were also survivors, or children of survivors, of the Holocaust, and who suffered from long-term trauma--what is now known as PTSD. An opera based on The Lost Childhood with music by Janice Hamer and libretto by Mary Azrael has been performed several times over the years, most recently in Los Angeles and Tel Aviv.
