The Society appears to have arranged for Rose, alongside Louisa Stammwitz and Isabella Clarke, to be mentored by Elizabeth Garrett (later Anderson) at her St Mary's Dispensary for Women and Children in Marylebone, which opened in 1866.
[4] Minshull and Stammwitz, alongside Isabella Clarke all studied at Dr Muter's South London School of Pharmacy which opened in Kennington in 1870, allowing these aspiring women pharmacists to receive a comprehensive pharmaceutical education.
Louisa Stammwitz recalled later "Miss Minshull and I had considerable difficulty in obtaining instruction in a chemical laboratory until Dr Muter very kindly opened his to women.
Minshull, Hart and Stammwitz petitioned the PSGB Council to allow ladies access to its labs, stating in a letter to the Pharmaceutical Journal that “All we ask is to be allowed the same opportunities for study, the same field for competition and the same honours, if justly won.”[6] Permission for women to work in the labs was granted in 1877 after Minshull and Stammwitz had passed the PSGB Minor examination, the two of them achieving the top two places in the chemistry exam.
They made repeated applications for membership from 1875 onwards and in spite of Robert Hampson's campaign, the conclusion was apparently reached by some Council members "to avoid further agitation", rather than through a comprehensive belief in equal rights.
