  1. Hermann von Helmholtz

  2. Birth and family • He was born on August 31, 1821 in Germany • His dad was Ferdinand Helmholtz and was a teacher of philology • His mother was a Hanoverian lady

  3. Schooling • He went to University of Konigsberg and studied physics • His father wanted him to study medicine because of the financial support for medical students

  4. Achievements • His first scientific achievement was his discovery of the principle of conservation of energy while studying muscle metabolism. He tried to demonstrate that no energy is lost in muscle movement. But it was rejection of the speculative tradition of Naturphilosophie which was a dominant philosophical paradigm in German physiology

  5. More Achievements • In 1849 at Konigsberg, Helmholtz measured the speed at signal are carried along a nerve fiber. At that time most people believed that nerve signals passed along nerves immeasurably fast. He used a sciatic nerve of a frog and the calf muscle to which it attached. He used a galvanometer as his timing device and attaching a mirror to the needle to reflect a light beam across the room to a scale which gave greater sensitivity. He reported transmissions speeds in the range of 24.6 - 38.4 meters per second

  6. Death • He died in on September 8, 1894(1894-09-08) at the age of 73 in Charlotte burg, Germany
