place in Dokkum. Dokkum was a popular place that she visited often throughout her life. Catharina had close friends in that area, who were part of the ministry; she would go there to assist their personal deliveries, like the wife of a preacher, and other townspeople with difficult deliveries. She delivered the last baby in 1745 at the age of 88. She was quite wealthy towards the end of her life, after her second husband died. She even had five houses in her name. Catharina became a very experienced midwife. She recorded about 3000 cases of childbirth in her notebooks. She traveled around to help with difficult deliveries. During her career more than 92% of babies survived childbirth, a much better figure than is reported in other places at that time. She does not appear to have used any of the obstetric equipment, such as forceps, developed around that time in Holland. As a matter of fact, instrumental deliveries were exceptional. If needed, she would most likely have asked a man to use an instrument: she recorded six cases of herself using a crotchet, and ten asking a man-midwife to do so. She was very active and vivacious during deliveries. She participated in very risky births and was often called for lost cases. Published work Catharina Schrader kept notebooks, originally entitled “Memoryboeck van de Vrouwens”, in which she recorded 3060 deliveries. There exist nine of them and they cover January 9, 1693, through February 7, 1745. Along with the details of the births themselves, her journal entries included financial information, the mother's information, and prayers. When she retired, she wrote her memoirs that were later published and translated, in which she went over 122 of the most difficult cases she encountered, in greater detail, with the hope of helping other midwives. If her notebooks were for her own records, her memoirs were written as a guide for her successors. Catharina would write an entry on the same day she helped a mother birth a child. The reason her entries were so detailed is that she wished her apprentices and successors to have access to her experience and knowledge. Catharina also kept a separate diary for gynecological and surgical work. This was kept in as much detail as her birth cases. Her journals and memoirs were not too hard to interpret and translate. She wrote in a language that showed her
