Charles Richter (April 26, 1900 – September 30, 1985) was a scientist who came up with the Richter scale for measuring earthquakes, which bears his name. For part of his career, he worked alongside Beno Gutenberg at the Carnegie Institution of Washington. Among other accomplishments, the pair developed a seismograph, to measure the tectonic displacement of seismic waves. Richter also created maps of the areas most likely to undergo earthquakes in the United States.[1]
