Stephen Hales

Stephen Hales was an 18th-century scientist and clergyman known for his pioneering work in biology and physics. He made significant contributions to understanding how plants transport water from roots to leaves, developing early techniques to measure blood pressure, and studying ventilation and respiration. His experiments helped establish the scientific principles underlying biological processes and contributed to the development of physiology as a field. Hales's meticulous research and innovative methods laid important groundwork that still influences science today.
