Alonzo Richter was a male Human sociologist born in 2162. He gained fame in the first decade of the 2200s with the publication of the Richter Scale of Culture, a method of comparing diverse alien cultures. He continued to refine this scale in the following decades, as also established the Richter Institute to promote sociological studies and further improve his methods. In 2269, Richter appeared before the Federation General Council, in support of the Talin's petition for de facto Federation membership. (TOS novel: Prime Directive)
