in later years and today lives in Amstelveen, outside of Amsterdam. She is the girl second from right in the "10 birthday" picture. Juultje Ketellaper and Martha van den Berg are two other childhood friends of Anne's who appear in the picture of Anne's 10th birthday party. Very little is known about either girl. Juultje, the very tall girl near the center, was gassed by the Nazis in Sobibór. She may have been a Montessori schoolmate of Anne's or merely a neighborhood friend. Martha, on the far right in the photograph, survived the war. Martha was Anne's Montessori schoolmate and is seen in another picture with Anne taken during Anne's last term at Montessori. Hannelore "Hansi" Klein (Laureen Nussbaum) was exactly midway in age between Anne and Margot. Hansi was an exception among those who knew Anne - she was rather indifferent about Anne and idolized Anne's sister Margot instead. But Anne, Hansi, and Hansi's two sisters performed in a holiday play about a vain princess who is punished with a long nose for her vanity, until she sees the error of her ways. Anne played the princess; Hansi noted that she played the role to perfection and had "natural charisma". Most people felt that Margot was the more beautiful of the Frank sisters, but Hansi observed that Anne, in her opinion, was prettier than Margot because "she [Anne] was always smiling". Aside from those anecdotes, however, Hansi thought of Anne primarily as a noisy chatterbox, and "a shrimp", and she was surprised and impressed with Anne's inner depth upon reading the diary much later. Hansi married a young physician after the war and, upon emigrating to America, changed her first name to "Laureen". She ultimately became a professor of foreign literature and languages at Portland State University. Gertrud Naumann was a friend, companion, and occasional babysitter of Anne and Margot's in Germany. Although several years older than Margot, this friendly girl always played with both of the Frank sisters, and she was a neighborhood favorite of both Mr. and Mrs. Frank's. After the Franks moved to Amsterdam, Gertrud kept contact with them through letters. Being Christian, Gertrud and her family were able to avoid persecution in the war. Gertrud was one of the first friends in Germany with whom Otto Frank got in touch after the war. In 1949, Gertrud married Karl Trenz. She died in 2002 at the
