What did the work of Lister and Ehrlich have in common?

The work of Joseph Lister and Paul Ehrlich both significantly advanced the field of medicine through their innovative approaches to infection control and treatment. Lister is known for introducing antiseptic techniques in surgery, reducing postoperative infections and improving patient outcomes. Meanwhile, Ehrlich developed the concept of selective toxicity, leading to the creation of effective treatments for Infectious Diseases, notably with the development of the first synthetic antimicrobial drug, Salvarsan. Both pioneers emphasized the importance of scientific principles in improving health and reducing disease.
