Stephen Hales () a fost un preot, medic, chimist și inventator englez. El a adus contribuții majore într-o serie de domenii științifice, inclusiv botanică, chimie pneumatică și fiziologie. A fost prima persoană care a măsurat presiunea arterială. De asemenea, a inventat mai multe dispozitive, printre care un ventilator, o chiuvetă pneumatică și o pensă chirurgicală pentru îndepărtarea pietrelor la vezica urinară. În plus față de aceste realizări, a fost filantrop și a scris o lucrare populară despre intemperanța alcoolică.
