Martin Ira Glassner of Hamden traveled all over the world as a Foreign Service officer during the late 1950s and early 60s. Now, 74, and a retired professor, he has written and edited more than 50 books, articles and essays on topics dealing with geography and political science. But his latest work has nothing to do with those two subjects. Glassner is the editor of \"And Life is Changed Forever: Holocaust Childhoods Remembered,\" a collection of stories from child survivors of the Holocaust. The book is available this month through Wayne State University Press. It features first-person narratives from 20 child survivors. The book also features analyses from child survivor Robert Krell, a retired professor of psychiatry, who specializes in dealing with the survivors of the Holocaust and other traumatic experiences.
