Henrietta Zamenhof is the widow of Ludwig Zamenhof.
Their marriage was always a marriage of convenience, but the couple were civil to each other, and got along fine. However, after their son's death, their marriage almost collapsed.
Mrs. Zamenhof sought treatment for grief and depression, and also reported hallucinations. After meeting with Dr. Aurelius, it seemed there was a familial problem with her husband, however, the treatment was suddenly stopped.
Mrs. Zamenhof is very well schooled in history and literature, and in the past has a semi-successful column on society affairs. She lives alone, with 3 people in her staff (a maid, house keeper, and cook).
