Both Aldis and her husband were active in social reform efforts, commenting on matters relating to vaccination, vivisection, atrocities in Jamaica and the Congo, and women's access to higher education. Aldis was also active in efforts to get the Contagious Diseases Act repealed, and to end legalised prostitution in India.[1] Aldis is considered one of the leaders in the campaign to allow women to enter Durham University.[5] She spoke publicly about the unfair treatment received by women students at Cambridge University, who were at that point only allowed to sit the Tripos by special permission, and could only gain a certificate in recognition of their success.
