Otto Frank began working at the Opekta Works. Opteka was a company that sold pectin. Otto Frank found an apartment on the Merwedeplein (Merwede Square) in Amsterdam. By February 1934, Edith and the children had arrived in Amsterdam, and Anne and Margot began going to school. Margot went to public school and Anne went to a Montessori school. Margot enjoyed math, while Anne preferred reading and writing. Her friend Hanneli Goslar later remembered that from when she was young, Anne often wrote, though she tried to hide what she wrote and did not like talking about it. Margot and Anne had very different personalities. Margot was polite, quiet, and thoughtful, while Anne was brave, energetic, and friendly.
