In 1874, physician Sir William Roberts noted that cultures of the mold Penicillium glaucum that is used in the making of some types of blue cheese did not display bacterial contamination.
In 1874, the Welsh physician William Roberts, who later coined the term "enzyme", observed that bacterial contamination is generally absent in laboratory cultures of Penicillium glaucum. John Tyndall followed up on Burdon-Sanderson's work and demonstrated to the Royal Society in 1875 the antibacterial action of the Penicillium fungus.

In 1874, Blackwell established a women's medical school in London with Sophia Jex-Blake, who had been a student at the New York Infirmary years earlier. Blackwell had doubts about Jex-Blake and thought that she was dangerous, belligerent, and tactless. Nonetheless, Blackwell became deeply involved with the school, and it opened in 1874 as the London School of Medicine for Women, with the primary goal of preparing women for the licensing exam of Apothecaries Hall. Blackwell vehemently opposed the use of vivisections in the laboratory of the school.
