Popper was born in Vienna and educated at the Academy of Commerce in Prague. As a little girl she had been to Montessori nursery school in Vienna. When the Germans came in on March the thirteen's 1938 she visited the gymnasium, and suddenly most of the children yelled 'Get out of here, you Jew.' In 1938, after Germany's annexation of Austria, when she was twelve years old, her family having Czech citizenship fled to the region formerly known as Czechoslovakia to escape the Nazis. Unfortunately this move provided only temporary safety. In spring 1939 her father left for Belgium and England. They were to meet again only at the end of the summer of '46.
Four years later, in October 1942, she and her mother were sent to the Theresienstadt concentration camp, near Prague, and later on also aunts and grandmother. While living there she has been put twice on the list for being transported to Auschwitz and both times she managed her name to be removed from that list. In January 1943 she asked the Jewish Elder to take her out of the transport. Edelstein took her out of the transport because her mother had died that morning and she'd acquired different status by her mother's death.
She came to Terezin from Prague in October 1942, and left in May 1945 (when the Russians took over Terezin), from age 16 to almost 19 years, and worked the entire time as 'Betreuerin' (caregiver) in a children's home, L 318. L 318 was one of the orphan houses in the ghetto. Later in 1945 in Olesovice - in the Poemysl Pitter, Children's Rehabilitation Center, situated in a castle of baron von Ringhoffer not far from Prague - she was a tutor for a group of children who survived Terezin and other camps.
In 1945 Anna Freud took a small group of Terezin children to England, they were taken care of under Anna Freud's supervision. Some of the children's recollections were published with their permission. Anna Freud has written an article about them, and Gyömrői  has written an analysis of one of the children survivors. At that time Anna Freud often called Erna Furman to ask her about things that came up with the children from camp, hoping that Erna could clarify them.
Erna Furman's Terezin drawings were demonstrated at the Friedl Dicker-Brandeis's exhibit series in Japan in April–October 2002. They were included in the exhibit and on display for the first time, the drawings and diaries of Erna Furman, "a survivor of Terezin and pupil of Friedl."  Her materials were taken in a special corner of the exhibition, called 'Erna's Room'. She and Friedl Dicker-Brandeis had been close friends when they were both interned in the ghetto of Terezin during the Second World War.
A graduate of the Child Therapy Training Program offered by Anna Freud in Hampstead following World War II, Erna Furman was a child psychoanalyst, a licensed psychologist, and a teacher. She emigrated to the United States with the help of Anny Katan  in the 1950s.
She married Robert Furman, had two daughters, Lydia and Tanya, and lived in Cleveland, Ohio with her husband. Both were prominent and respected psychoanalysts. Erna Furman specialized in children and how children process grief. Of particular importance was her evidence that children as young as three essentially process grief no differently from adults and her insistence that children not be misled or deceived when a parent dies. She wrote:
In all bereavement, it is extraordinarily important that all of the realities of the death be known and appreciated by the survivor, particularly the cause of the death.
She practiced at the Hanna Perkins Center for Child Development and also saw patients in her Cleveland Heights home. She was a prolific writer; over the years she received extensive accolades for her contributions to psychoanalysis. She was made an honorary member of the American Psychoanalytic Association in 1999.

|“||You can say that I grew up in Vienna, I grew up in Prague, and I grew up in Terezin. Those were my ways of growing up. Coping with life. Not overwhelmed by the holocaust but deeply affected by it.||”|

I said I had to see him and walked in. He said: 'What do you want?' I said: 'I am only 16 years old and still have to live. I am not ready to go in the transport and you have to take me out.
