Helena had a firm interest in nursing, and was the founding chair of the Ladies' Committee of the British Red Cross in 1870, playing an active role in recruiting nurses and organising relief supplies during the Franco-Prussian War. She subsequently became President of the British Nurses' Association (RBNA) upon its foundation in 1887. In 1891, it received the prefix "Royal", and received a royal charter the following year. She was a strong supporter of nurse registration, an issue that was opposed by both Florence Nightingale and leading public figures. In a speech Helena made in 1893, she made clear that the RBNA was working towards "improving the education and "status" of those devoted and self-sacrificing women whose whole lives have been devoted to tending the sick, the suffering, and the dying". In the same speech, she warned about opposition and misrepresentation they had encountered. Although the RBNA was in favour of registration as a means of enhancing and guaranteeing the professional status of trained nurses, its incorporation with the Privy Council allowed it to maintain a list rather than a formal register of nurses.
