Emil von Behring was a German physiologist who developed a serum to treat diphtheria. Diphtheria was a deadly disease, especially for children, so his work was a huge deal. Behringβs antitoxin worked by neutralizing the toxins produced by the bacteria. Think of it like an antivirus software for your body, fighting off harmful invaders. His discovery led to the development of other life-saving vaccines.
