Friends and descendants of Charles Richter, the physicist who created the first scale to measure the magnitude of Earthquakes, gathered at the Richter Roundabout near Edgewood High School on Friday, April 21, to celebrate his birthday. Richter was born in Butler County and moved to California as a youth. Celebrants enjoyed “earthquake cookies” and placed rocks at the base of the Ohio Historical Marker commemorating Richter and his achievements.
