went on to become the principal of the first girls' school in Christiansborg, site of a Danish fort on the Gulf of Guinea and now part of modern-day Accra. She was to return there in later life, after moving to her second husband's hometown of Gerlingen, Germany, and staying there with him until after his death on 13 December 1876. Back in the Gold Coast in 1877, her participation in school life was no longer as intense as it had formerly been; the fact that her daughter Augusta Amalie then worked for the Mission at the Christiansborg girls' school from 1889 to 1892, after teaching at the Girls' Institute in Aburi from 1877 to 1883 , however, meant that Catherine's contribution to female education in the Gold Coast was intergenerational. In any event, she had worked in schools and communities with Johannes at several locations over the course of their marriage: in 1854 they were living in Abokobi at the foot of the Akwapim Ridge, were later posted to Akropona in the Volta Basin region and then, from 1859, spent twelve years in Odumase Krobo, in south-eastern Gold Coast. Zimmermann himself had integrated so well into Ga society that he was elected to the chieftaincy council of King Odonkor Azu in the Ga-Adanme state of Krobo (Jenkins, 1988, fn. 13; Haenger, 1995, p. 13).
