In 1995, the New York Times ran an article titled "Pasteur's Deception". After reading Pasteur's lab notes, the science historian Gerald L. Geison claimed that Pasteur had given a misleading account of the preparation of the anthrax vaccine used in the experiment at Pouilly-le-Fort. However, in the New York Review of Books, Max Perutz published an article that strongly defended Pasteur. These allegations of Pasteur's flaws have not been backed up and therefore, remain completely unknown. Most of the articles published about Pasteur are portrayed positively.
