CINCINNATI -- Fans of the Ohio native credited with developing the Richter scale for rating earthquake magnitude don't want his name and legacy forgotten.
They are determined to keep Charles Richter from fading from public memory as other magnitude measurements have been developed and references to the Richter scale are used less in reports about earthquakes.
A group of historians and Richter supporters has joined with local officials to establish an annual celebration of his life near the southwest Ohio site where Richter was born April 26, 1900.
This year's Charles F. Richter Day ceremony on his birthday will be held Friday in Butler County, about 25 miles north of Cincinnati.
Richter, working with other scientists, is credited with developing the method for rating magnitude by measuring the shock waves produced.
