Charles F. Richter was an American seismologist best known for developing the Richter scale, a system for measuring the magnitude of earthquakes. Born on September 26, 1900, in Hamilton, Ohio, he dedicated his career to studying seismic activity and understanding the Earth's movements. His work significantly advanced the field of seismology and helped improve earthquake safety. Richter earned his Ph.D. from the California Institute of Technology and later became a professor there. He published numerous scientific papers and contributed to the establishment of the Seismological Society of America. Richter's legacy continues to influence how we measure and respond to earthquakes today.
